Testing 6 - 15
7. If the reason for performing the rectifier tests was to affirm
the operation of the rectifier, and was not part of total plant
testing, restore the rectifier to service by following the
procedures in “Restoring a Rectifier to Service” in Section
7. If this is part of total plant testing, leave the plant control
cable disconnected at this time, until directed to reconnect
it as part of another plant procedure.
Bringing the
Rectifier On
Line
The following steps bring the rectifier into service in preparation
for testing on line. The term “on line” means a battery string
and/or office load is connected to the rectifier.
Perform all the preliminary checks on the plant before testing the
rectifiers. The same precautions for personal safety and
equipment protection should be taken as when testing off line
(see “Precautions” in this section).
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 product manual for instructions.)
3. At the ac service panel supplying power to the rectifier,
insert the input fuses assigned to the rectifier or turn the
circuit breaker On.
