Start-Up Scope of Work
Attachment L-2
This scope of work is shared by UPS, Eaton DC, Eaton PDU/PDR/RPP/STS, Flywheel, Non Eaton UPS
and Distributed Bypass. The following is an outline of general procedures and tests, if applicable, that are
normally performed by Field Service Personnel during the course of a standard start-up for new units or
to recertify and restart a previously started UPS. All checks and processes may not be applicable to all
equipment models.
UPS/PDU/RPP/STS START-UP PROCEDURE
1. VISUAL INSPECTION
1.1. Visually inspect all equipment for signs of shipping damage and/or foreign materials.
1.2. Check all battery cells for proper electrolyte levels.
1.3. Observe type of ventilation, room cleanliness, use of proper signs and any safety related items
that may be noteworthy
2. MECHANICAL INSPECTION
2.1. Check internal power connections in UPS module for tightness while observing proper safety
precautions.
2.2. Check all control wiring terminations and plugs in UPS module for tightness and/or proper setting.
2.3. Check to see that all factory connections, power modules, subassembly pans and legs are
secure.
2.4. Inspect the ISBM or IOM (inspect auxiliary connections)
3. ELECTRICAL PRECHECK
3.1. Check system for ground faults at all power inputs and outputs
3.2. Check DC bus for short circuits and proper polarity.
3.3. Checks input and bypass power terminations for proper voltages and phase rotation inside all
modules.
3.4. Check and adjust, if necessary, all power supply voltages.
3.5. Verify CTO and Serial numbers programmed into system match the equipment labels
4. INITIAL UPS, PDU ENERGIZATION
4.1. Verify all system annunciations are in "go" condition.
4.2. Energize unit(s) and verify proper DC walkup and AC phase on.
4.3. Check DC link holding voltage, AC output voltages and output waveforms.
4.4. Check final DC link voltage and inverter AC output. Adjust if required.
4.5. Check for proper synchronization with bypass source.
4.6. Check voltage differences between inverter outputs and bypass source.
5. INITIAL DC SYSTEM ENERGIZING
5.1. Installation of one rectifier
5.2. Initial power up of equipment
5.3. Verification of correct voltage / polarity for rectifiers
5.4. Installation of all rectifiers
5.5. Verification of proper operation of rectifiers
5.6. Verification of proper operation of the system controller
