Installing the Option Module Chapter 2
Connecting the Option
Module to the Drive
1. Insert the option module into Port 4, 5, or 6 and tighten the module
mounting screws into the pod mounting bracket. To properly ground the
module to the drive, torque both mounting screws to 0.45...0.67 N•m
(4.0... 6.0 lb•in).
2. When another module (I/O, encoder, communication, and so forth)
resides in the adjacent port to the left of the 20·750-PNET2P option
module—and the lower mounting screw of that module is a larger T15
Torx head screw, perform additional steps 2a through 2c. If the port is
empty or the adjacent module already uses the smaller T8 Torx head
mounting screws, save this spare screw for future use.
The option module is shipped with a small bag containing a spare T8 Torx
head mounting screw. The larger T15 Torx head mounting screw on the
adjacent left module may mechanically interfere with the clips on the
Profinet cable connector when attached to the Profinet module. This may
cause problems connecting or removing the connector. To prevent this,
perform the following steps.
a. Remove the adjacent module's lower mounting screw, the T15 Torx
head screw closest to the bottom of the pod mounting bracket.
b. Replace the larger T15 Torx head screw with the smaller spare T8 Torx
head mounting screw.
c. Tighten the mounting screw to the pod mounting bracket to properly
ground the adjacent module to the drive. Torque the screw to
0.45...0.67 N•m (4.0...6.0 lb•in).
IMPORTANT Remove power from the drive before installing the option module in the
drive control pod.
TIP To remove the captive T15 Torx head screw, the module must be
removed to back the screw out of the mounting clip.
