Use the plastic keying bands, shipped with each I/O chassis, to key the I/O slots to accept only this type of module.

The module circuit board is slotted in two places on the rear edge. The position of the keying bands on the backplane connector must correspond to these slots to allow insertion of the module. You can key any connector in an I/O chassis to receive this module except for the left-most connector reserved for adapter or processor modules. Place keying bands between the following numbers labeled on the backplane connector:

.Between 10 and 12

.Between 20 and 22

1. Turn off power to the I/O chassis.

2. Place the printed circuit board on the rear module in the plastic tracks at the top and bottom of the slot that guide the module into position.

3. Do not force the module into its backplane connector. Apply firm, even pressure on the module to seat it properly.

4. Snap the chassis latch over the top of the module to secure its position.

5. Connect the field wiring arm to the module.

6. Make wiring connections to the field wiring arm as indicated in Figure 1.

Connections to the output module are made to the field wiring arm (cat. no.1771-WH) shipped with the module. An optional fused field wiring arm is available (cat. no. 1771-WHF) which provides individual fusing for each circuit. Attach the field wiring arm to the pivot bar on the bottom of the I/O chassis. The field wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires.

Refer to Figure 1. You must supply ac (L1) at terminals A through D on the field wiring arm. You need four ac connections to accommodate the total required surge rating on the module without overstressing any single connection on the field wiring arm. Jumper all ac (L1) connections together to prevent module damage
