expansion cards in

920i

indicators:

1. Disconnect indicator from power source.

Disconnect power before removing

indicator backplate.

2. Place indicator face-down on an antistatic

work mat. Remove screws that hold the

backplate to the enclosure body.

Use a wrist strap to ground yourself and

protect components from electrostatic

discharge (ESD) when working inside

the indicator enclosure.

3. Carefully align the large option card

connector with connector J5 or J6 on the CPU

board. Press down to seat the option card in

the CPU board connector.

4. Use the screws and lockwashers provided in

the option kit to secure the other end of the

option card to the threaded standoffs on the

CPU board (see Figure 1).

5. Make connections to the option card as

required. Figure 2 shows connections

available on connector J3 (up to eight digital

I/O channels). Connector J2 provides all 24

channels using a 50-pin ribbon cable (see

Table 3).

Use cable ties to secure loose cables inside the

enclosure.Once cabling is complete, position

the backplate over the enclosure and reinstall

the backplate screws. Use the torque pattern

shown in Figure 4 to prevent distorting the

backplate gasket. Torque screws to 15 in-lb

(1.7 N-m).
