2. EQUIPMENT OPERATION AND MAINTENANCE
2.1 EQUIPMENT OPERATION
2.1.1
AC Turn-On Procedure
After making all connections to the power supply and making sure they are tight, follow this procedure to
energize the equipment:
1. Place the “Float-Equalize” rocker switch in the “Float” position.
2. Close the DC circuit breaker. The battery will charge the filter capacitors connected across the DC
output. The DC voltmeter on the front panel should read the battery voltage.
*Note: In-rush current may trip the breaker. If so, reclose.
3. Close the AC circuit breaker. The output current will build up gradually due to the “walk-in” or
“soft-start” characteristic of the equipment.
If the equipment is used without a battery, the capacitor will become charged when the AC breaker is closed. In
this instance, both the current and voltage will build up gradually, provided some load is connected.
2.1.2 Alternate AC Turn-On Procedure
After making all connections to the power supply and checking them for tightness use the following procedure to
energize the equipment:
1.
Place the float/equalize rocker switch in the float position and set the local/remote switch to local.
2. Close the ac circuit breaker. Wait several seconds for the dc voltage to reach its set point.
3. Close the dc circuit breaker. If inrush of current trips the dc breaker, reset it and proceed. Refer to
drawings in back of manual for location of switches.
2.1.3
AC Turn-Off Procedure
In order to de-energize or turn off the power supply, the following steps need to be followed in the indicated
order:
1. Open the AC circuit breaker.
2. Open the DC circuit breaker.
2.1.4 Float/Equalize Settings
The float and equalize voltage levels are factory set. These settings are indicated by a red card attached on the
inside front of the equipment. However, you may wish to change the settings to fit your particular application.
The table 2-1 shows typical float and equalize voltages on a per cell basis for different types of batteries.
