Bringing the
Rectifier On
Line
The following steps bring the rectifier into service in preparation
for testing on line. The term “on line” means that a battery string
and/or office load is connected to the rectifier.
Perform all the preliminary checks on the plant before testing the
rectifiers. Take the same precautions for personal safety and
equipment protection as when testing off line.
1. Verify the ac supply and rectifier controls are as shown in
Table 6-C.
2. If the rectifier is in a microprocessor-controlled plant with
an efficiency algorithm feature, disable this feature. (See
the controller manual for instructions.)
3. Reconnect the + and - output leads to TB3 in the rectifier.
4. Remove the tape and reconnect the rectifier’s ground
output lead to the plant charge ground bus bar.
5. Remove the tape and reconnect the rectifier's “hot” output
lead to the plant charge bus bar.
6. At the ac service panel supplying power to the rectifier,
insert the input fuses assigned to the rectifier or turn the
circuit breaker On.
7. To bring the rectifier into service:
