Some option cards come with ground wires of different lengths for connecting the card to the drive. Select the ground
wire with the most appropriate length.
Note: There are only two screw holes on the drive for ground terminals. When connecting three option cards, two ground wires will need
to share the same ground terminal.
4.
Wire the option card to the terminal block on the option card.
Refer to the option card manual for wiring instructions.
When installing option cards to models CIMR-Ao2A0004 to 2A0040, CIMR-Ao4A0002 to 4A0023,
and CIMR-Ao5A0003 to 5A0011, it may be necessary to route the cables connected to the option through the top
cover to the outside. In this case, cut out the perforated openings on the left side of the drive top cover, being careful
not to leave any sharp edges that may damage the cable.
Models CIMR-Ao2A0056 to 2A0415, CIMR-Ao4A0031 to 4A1200, and CIMR-Ao5A0017 to 5A0099 have enough
space to keep all wiring inside the unit.

5.
Replace the front cover and digital operator on the drive.
Note: 1. Leave enough space when wiring to easily reattach the front cover. Make sure no wires get caught between the front cover
and the drive.
2. Any exposed wiring will void the wall-mount enclosure rating.
