Procedure 1: Bus Voltage Measurement

The DC bus voltage level is determined by monitoring the (+) and (–)

measurement points. Their location varies by drive controller model

number as listed in Table 26 and shown in Figure 25. The drive

controller model number is listed on its nameplate.

To measure the DC bus capacitor voltage:

1. Disconnect all power from the drive controller including external

control power that may be present on the control board and the

option board terminals.

2. Wait ten minutes for the DC bus capacitors to discharge.

DANGER

HAZARDOUS VOLTAGE

• Read and understand the bus voltage measurement procedure

before performing the procedure. Measurement of bus capacitor

voltage must be performed by qualified personnel.

• DO NOT short across DC bus capacitors or touch unshielded

components or terminal strip screw connections with voltage

present.

• Many parts in this drive controller, including printed wiring boards,

operate at line voltage. DO NOT TOUCH. Use only electrically

insulated tools.

Electrical shock will result in death or serious injury.
