It is labeled "Output Relay." It is a single-pole, single-throw, latching relay. See "Outputs" in
Chapter Five for more information.
NOTE: All wiring should comply with section 17 of the UL requirements.
STRAIN RELIEF
Strain relief clamps are provided on the Express II enclosure to prevent wiring from being pulled
from the circuit board or damaged when passing through the enclosure. To use the strain relief,
thread wires through the clamp and the clear rubber bushing. Position the bushing in the clamp
and tighten the screws on either side so that the wiring does not move. See Figure 13.

INSTALLING OUTPUT EXPANSION CARDS
To install an output expansion card:
1. Turn the unit off. Damage may occur to the motherboard or to the output card if installed
while power is still on.
2. Remove the screws and blank plate of the first available slot from left to right.
NOTE: Always install cards side by side — do not skip a slot.
3. Hold the card with the LEDs at the top with the DIN connector plug on the card lined up with
the DIN connector socket on the motherboard.
4. Insert the DIN connector plug into the DIN connector socket and press down slightly to
connect.
5. Turn the unit on.
Wire the outputs for the configuration you want--manual or auto--as described above. See
Chapter 5 for programming information.
NOTE: When installing a combination of input and output cards, always install the input cards
grouped together in the left slots and the output cards to the right of them. If you install an input
expansion card after an output card has been installed, you must disconnect the output card,
install the input card in its place, and reinstall the output card to the right of it.
