Preventive Maintenance

7.1 Safety Overview

Hazardous voltages and currents are present in this equipment! Hazardous energy is stored and will still be present even when the equipment is
turned off and removed from power mains!
Personal protective equipment is required when working on this equipment. This includes safety glasses, insulated gloves, and insulating blankets to
prevent shorts or accidental contact with live circuits.
LOTO (Lockout-Tagout) procedures should be used when service cannot be completed in one visit.
Insulated tools are required for service inside power modules or battery cabinets when working hot.
Use a voltmeter to verify that voltage has been removed before servicing any module.
Use a voltmeter to determine that voltages and polarities are correct before re-connecting any batteries or battery cabinets.
If you are working with someone else, be certain that you know what the other person is doing at all times AND that the other person knows what
you are doing!

7.2 Suggested tools and supplies

• Insulated tools:
Torque wrench
Socket set, ratchet
Screwdrivers (Philips and common)
Magnetic Philips screw driver
Needle-nose pliers
Diagonal wire cutters
• Oscilloscope—199 Fluke Scope meter or equivalent
• Digital Multi-meter—189 Fluke or equivalent true RMS with diode scale
• Clamp-on Ammeter—AC/DC; true RMS
• Non-contact infra-red thermometer
• TIF tester (for battery module)
• Small soldering iron and rosin-core solder
• Insulated gloves
• ESD protective equipment (grounded pad, wrist strap)
• Insulating blanket
• Electrical tape
• Heat sink thermal compound
• Plastic ties

7.3 UPS Procedure

7.3.1
Check the LCD display and the LED panel for status and alarms. If the unit is operating normally and no alarms are present, or if the unit has an
active alarm, download the event log and failure power module identify (Please refer to chapter 3 and chapter 6 of "owner's manual").
7.3.2
Remove the rear, side, top and front covers. Perform an infrared scan on input and bypass breakers, cables and wire connections (terminal blocks,
internal connect, etc.), and other assemblies. What are we looking for? What temperature limits can not be exceeded?
7.3.3
Visually inspect cables for signs of overheated or damaged insulation. Visually inspect modules for damage and inspect bypass STS snubbers for
damage.
7.3.4
Measure Ø to Ø and Ø to Neutral main input voltage, bypass input voltage and enter those on the form. Note that phases R, S, T correspond to
A, B, C on the form. Compare the meter readings with the LCD display readings. If the voltage readings are correct within +/- 1%, check input
metering OK on the form. If there is a greater discrepancy, enter that in NOTES. Then what do we do? Is there a troubleshooting tree to reference
in the service manual?
