Bringing a
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.
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. At the ac service panel supplying power to the rectifier, insert the
input fuses assigned to the rectifier or turn the circuit breaker On.
Warning: DO NOT turn on the CB1 circuit breaker until indicated
in the procedure.
4. To bring the rectifier into service, do the following:
a. Turn the rectifier Power switch On. The green Power LED
must light. Wait 10 seconds.
