3. Connect one of the lead lines using one of the screws to the ground terminal.
Some option cards come with several different lead lines for connecting the card to the drive. Select the lead line
with the most appropriate length.
Note: There are only two screw holes on the drive for ground terminals. If three option cards are connected, two of the lead lines will
need to share the same ground terminal.

4. Wire the option card to the terminal block on the option card.
For wiring instructions, refer to the manual delivered with the option card.
When installing option cards to drive models CIMR-A2A0004 through 0040 and to models CIMR-A4A0002
through 0023, the cables connected to the option might need to be routed through the front cover to the outside.
In this case, cut out the perforated openings on the left side of the front cover. Make sure no sharp edges are left
that may damage the cable.
Models CIMR-A2A0056 through 2A0415 and 4A0031 through 0675 have enough space to keep all wiring
inside the unit.

5. Place the front cover and digital operator back onto the drive.
Note: 1. Leave enough space when wiring so that the front cover can be easily reattached. Make sure no wires get caught between the front
cover and the drive.
2. Any exposed wiring will void the wall-mount enclosure rating.
