LIEBERT Equipment We Repair — By Category
LIEBERT Product Lines We Repair
Our engineers are trained on the full LIEBERT product range. Below are the major product families we service.
Liebert UPS Systems (Static and Modular)
Liebert manufactures a comprehensive range of uninterruptible power supplies including the Liebert eXL, Liebert NX, and Liebert EXM series. These systems provide mission-critical backup power with high efficiency and scalability. Common repair issues include battery management failures, inverter module faults, capacitor degradation, and control board failures.
Liebert Precision Cooling and Row-Based Systems
Liebert precision air conditioning units and in-row cooling systems maintain critical ambient conditions in data centres and server rooms. These include the Liebert DSE (Direct Snap-In Enclosure) and Liebert CRV (Computer Room Vertical) units. Repairs often address refrigerant leakage, compressor failure, fan motor burnout, and temperature sensor malfunction.
Liebert Power Distribution Units (PDU) and Switched Rack PDUs
Liebert PDU modules provide intelligent power distribution, metering, and environmental monitoring for rack-mounted infrastructure. These devices include metered outlet strips, switched PDUs, and monitored power distribution units. Common failures include relay sticking, circuit breaker trips, metering sensor drift, and SNMP communication module failures.
Liebert Battery Modules and Power Conditioning
Liebert supplies external battery cabinets and integrated power conditioning equipment designed for extended runtime and grid stabilization. These include sealed lead-acid (VRLA) battery packs and lithium-ion modules. Repair challenges include battery cell failure, BMS (Battery Management System) circuit faults, charging circuit malfunction, and temperature compensation module issues.
Liebert IntelliSlot and Modular System Architecture
Liebert modular UPS systems employ hot-swappable power modules, battery modules, and control cards. The IntelliSlot architecture allows on-the-fly capacity upgrades and redundancy. Common repair issues include module communication failure, hot-swap connector corrosion, firmware version mismatch, and slot controller board faults.
Liebert Network Management and Monitoring Software
Liebert supplies Network Management Cards (NMC) and software suites for remote monitoring, alerting, and graceful system shutdown. Products include Liebert NMC, Liebert Nform, and vendor-specific monitoring integrations. Repairs address Ethernet port failure, internal memory corruption, firmware update failures, and communication protocol stack issues.

Common LIEBERT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LIEBERT equipment arriving at our workshop.
- ✓UPS Inverter Module Output Failure or Low Voltage — Liebert inverter modules experience DC-to-AC conversion failures due to IGBT transistor degradation, electrolytic capacitor aging, or control signal loss from the main power board. High-temperature operation and repeated overload events accelerate component failure.
- ✓Battery Management System (BMS) Communication Failure — Liebert battery strings communicate with the main controller via serial or modular architecture. Communication loss occurs due to connector corrosion, BMS board firmware corruption, shorted cells triggering safety shutdown, or defective battery monitoring daughterboards.
- ✓Precision Cooling Unit Compressor Shutdown or Reduced Cooling Capacity — Liebert precision coolers fail when compressors overheat due to refrigerant undercharge, fan motor bearings seize, or suction-side filter blockage occurs. Electrical failures in the compressor contactor or thermal overload switch also prevent cooling operation.
- ✓PDU Outlet Relay Sticking or Intermittent Power Loss to Connected Equipment — Liebert switched PDU outlet relays experience contact erosion and sticking after extended switching cycles or when handling inductive loads. Arc discharge on relay contacts produces oxide layers blocking current flow. Control signal line failures to the relay coil also prevent switching.
- ✓Liebert UPS Bypass Switch Malfunction or Static Transfer Switch Failure — Liebert bypass/static transfer switch (STS) modules fail when thyristor or SCR semiconductor devices degrade, triggering circuit logic loses synchronization with utility voltage phase, or capacitor banks drift causing improper voltage regulation during bypass mode.
- ✓Liebert Network Management Card Unreachable or Intermittent Remote Monitoring — Liebert NMC (Network Management Card) failures stem from Ethernet port PHY chip malfunction, corrupted firmware in the NMC flash memory, loose internal connectors, or conflicting IP address assignment on the network.

Frequently Asked Questions — LIEBERT Repairs
Does Synchronics repair Liebert equipment at multiple locations across India?+
Yes, Synchronics operates a pan-India service network from our headquarters in Vadodara, Gujarat. We arrange express pickup and delivery of Liebert UPS systems, cooling units, and PDU modules from all major Indian cities including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, and Kolkata. Our facility houses specialized test benches for Liebert high-power systems, battery load banks, and precision cooling evaluation chambers. Repairs are completed with full technical documentation and warranty.
What is the typical turnaround time for Liebert UPS repair at Synchronics?+
Synchronics targets 5-7 working days for diagnosed Liebert UPS module repair including component replacement, functional testing, and battery verification. Emergency same-day/next-day component swaps are available for critical data centre environments. Repair timelines depend on parts availability and complexity; we communicate expected timescales before work commences. Customers receive detailed technical reports explaining root cause, remedial actions, and preventive maintenance recommendations for Liebert systems.
Do you repair Liebert precision cooling units and what common issues affect them in Indian climate conditions?+
Synchronics specializes in Liebert DSE, CRV, and in-row cooling system repairs. In India's tropical and monsoon climate, Liebert precision coolers experience accelerated corrosion of aluminium coil fins, refrigerant moisture contamination, and condensation on evaporator coils when humidity spikes unexpectedly. Our technicians perform humidity-hardened installation verification, refrigerant system flush and evacuation, and coil coating inspection. We recommend annual preventive maintenance for Liebert cooling systems operating in coastal or high-humidity Indian regions to avoid compressor damage.
Can Synchronics repair Liebert battery strings and battery management modules?+
Yes. Synchronics conducts full battery string diagnostics using DC load testers that measure individual cell voltage, string capacity under load, and internal impedance. Failed cells and weak strings are identified and replaced. Battery Management System (BMS) boards are tested for firmware integrity, sensor calibration, and communication interface function. We source OEM Liebert battery modules and compatible VRLA/lithium-ion replacements. All battery repairs include capacity verification before return to customer.
What documentation and warranty does Synchronics provide for Liebert repairs?+
Each Liebert repair is documented with a comprehensive technical report detailing fault root cause, components replaced, test parameters, and load-test performance data. We provide 12-month warranty on replaced modules and 6-month warranty on repaired PCB assemblies. Extended warranty options are available. Synchronics maintains traceability records for spare parts and firmware versions used, supporting audit compliance for regulated Indian industries like banking and healthcare.
How do I send my LIEBERT unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt.
What is the cost of repairing a LIEBERT drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on LIEBERT repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your LIEBERT unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
