If deviations from the factory settings are desired, refer to Section 1.18
“Navigating the Simple Controller” in the PECO II Rectifier System Manual:
127NHL-IBWS manual.
To verify system connections, refer to Chapters 2 & 3 for mechanical and
electrical installation information in the PECO II Rectifier System Manual:
127NHL-IBWS manual.
Verify alarms if extended to an Alarm Termination Panel.
Check operation and calibration of Plant Volt and Amp Meter.
It is important that the rectifier fans be inspected regularly to make sure they
aren't damaged or filled with dust. Be sure the plant is getting adequate
ventilation by ensuring there are no restrictions in the surrounding area such as
boxes leaning against any of the plant components, or within 18 inches of them.
Inspect all cable connections, and tighten if necessary. System connections for
AC input, battery, and distribution are plug-in, and should be checked to ensure
they are properly seated.
Ground studs/bolts should have the following torque:
Bolt Size (inches) Bolt Steel (Grade 5)
FT LBS / IN LBS
¼ 7.6 / 91.2
5/16 15.3 / 183.6
3/8 27.0 / 324.0
7/16 43.0 / 516.0
½ 64.0 / 768.0
Rectifiers
Verify Rectifier voltage and amperage setting: High Voltage (HV), Current Limit,
Low Current, Float as applicable.
Verify Alarms are extended to Plant Controller.
