PowerFlex 750-Series AC Drives
Option Module Installation
Compatible port locations may be restricted for each module. An icon
with position number(s) is provided to indicate which option module
ports are compatible. For example, the icon to the right indicates that
the option module is only compatible with port 4.
To install an option module:
1. Firmly press the module edge connector into the desired port.
2. Tighten the top and bottom retaining screws.
–
Recommended torque = 0.45 N•m (4.0 lb•in)
– Recommended screwdriver = T15 Hexalobular
ATTENTION: Hazard of equipment damage exists if an option module is installed or
removed while the drive is powered. To avoid damaging the drive, verify that the
voltage on the bus capacitors has discharged completely and all control power is
removed before performing any work on the drive.
Frames 1…7: Measure the DC bus voltage at the Power Terminal Block by measuring
between the +DC and -DC terminals (refer to
Figure 79 and Figure 80 for location),
between the +DC terminal and chassis, and between the -DC terminal and the chassis. The
voltage must be zero for all three measurements.
Frames 8…10: Measure the DC bus voltage at the DC+ and DC- TESTPOINT sockets on the
front of the power module (refer to
Figure 83 ). The voltage must be zero
IMPORTANT Do not over-tighten retaining screws.
