Section 6: Power Supply Shutdown
If power supply shutdown becomes necessary at any time, observe the following procedure:
1. Operate the BATTERY CIRCUIT breaker to the OFF (O) position, then disconnect the battery cable
from the power supply.
2. Disconnect the line cord from the enclosure receptacle or operate the circuit breaker serving AC
utility power to the supply to the OFF position.
3. If desired, the AC output cable and any accessory cables may be disconnected.
Section 7: Maintenance and Adjustments
CAUTION
Other than the following Output Voltage Configuration procedure, there are
no field serviceable items inside the power supply cabinet. The cabinet
cover must not be removed except as described.
7.1 Preventive Maintenance
For optimum performance from your power supply, the following maintenance items should be performed at
least every six (6) months, especially in areas where the power supply is subjected to extreme heat or cold.

Visually inspect the enclosure for signs of damage

Inspect the external status lamps for proper operation

Check the LCD display and the status LEDs for any alarm indications

Check all electrical connections

Check the batteries for signs of swelling, split cases or other damage

Check and record individual battery voltages

Check and clean battery terminals; bolts or wingnuts must be tight

Measure and record AC output voltage

Measure and record AC output current

Measure and record DC battery voltage

Initiate a 15-minute battery test routine to check battery health

Record all maintenance performed or parts replaced

Verify the power supply is in its normal mode of operation as indicated by the LCD display. Most
front panel LEDs should be illuminated green to indicate normal operation.

Close and lock the enclosure
7.2 Analog Adjustments
Several miniature potentiometers are located on the printed wiring boards of the power supply. These
potentiometers have been factory adjusted for proper voltage levels and for correct detection and
measurement thresholds.
Field adjustment of any potentiometer in the power supply must not be
attempted; otherwise, degraded power system performance or damage to equipment or batteries
may result.
If any potentiometer adjustments are suspected as a cause of operational trouble or erroneous
reporting, the entire power supply should be changed in the field then returned to a service center or the
factory for diagnosis and repair.
