Job Description

Position Summary

The UPS Technical Engineer will be responsible for the installation, commissioning, troubleshooting, and maintenance of UPS systems, battery banks, and voltage stabilizers at customer sites. This role requires strong hands-on experience, good electrical knowledge, and the ability to diagnose and resolve issues efficiently at the field level.

Key Responsibilities

1. Installation & Commissioning

Install UPS systems of various capacities (single-phase and three-phase). Install and connect battery banks, including VRLA/SMF batteries. Install and configure voltage stabilizers and related electrical equipment. Perform cable termination, panel connections, battery wiring, and breaker connections. Ensure proper earthing, isolation, and load test procedures during commissioning. Verify correct settings, calibrations, and system parameters before handover.
2. Preventive & Corrective Maintenance

Conduct preventive maintenance for UPS and battery systems as per schedule. Check battery health (voltage, internal resistance, specific gravity if applicable). Identify and replace faulty components: rectifiers, inverters, fans, controllers, breakers, batteries. Respond to emergency breakdown calls and carry out corrective maintenance. Validate alarms, logs, and event history to detect issues. Maintain stability and reliability of the UPS power environment.
3. Troubleshooting & Repair

Diagnose issues in UPS systems (no output, bypass failure, charging failure, overheating). Identify issues in battery banks (swollen batteries, leakage, imbalance, corrosion). Troubleshoot stabilizers, AVR units, and power-related faults. Coordinate with OEM support for advanced diagnostics when required.
4. Documentation & Reporting

Prepare installation reports, service reports, and preventive maintenance checklists. Maintain accurate records of battery readings, system parameters, replacement parts, and site observations. Provide feedback to the technical manager regarding recurring issues or component failures. Ensure all documentation is completed and shared on time after each site visit.
5. Safety & Coordination

Follow all electrical safety and HSE guidelines at site. Use PPE, tools, and testing instruments safely (multimeter, clamp meter, IR tester). Coordinate with project managers, contractors, and customers for scheduling site visits. Guide junior technicians if required.

Qualifications & Experience

Minimum Diploma in Electrical Engineering or equivalent Minimum 3 years of hands-on experience in installation and maintenance of:
UPS systems (static UPS preferred)

Battery banks (12V SMF, VRLA, tubular)

Stabilizers / Automatic Voltage Regulators (AVR)

Preference:

Candidates with GCC or Oman experience will be given priority.

Technical Skills Required

Strong understanding of electrical power systems and single/three-phase connections. Ability to read UPS wiring diagrams, SLDs, and installation manuals. Experience in battery configuration (series, parallel, battery racks, DC bus connections). Understanding of safety procedures for handling batteries and high-voltage systems. Skilled in using electrical testing tools for diagnostics. Basic knowledge of generator-UPS synchronization and bypass operations is an advantage. Familiarity with branded UPS systems (Ablerex, APC, Emerson, ABB, etc.) preferred.

Soft Skills
