Care must be taken when installing the zone input and zone output field wiring to
prevent possible cross wiring. This can cause severe damage to the system when
powered up or when zone is activated.
The screw terminals can accommodate one 12-18 AWG or two 16-18 AWG.
If the total output of all 8 zones exceeds 12 amps, a single PSC-12 cannot be used to
supply the ZIC-8B. Refer to the PSC-12 Installation Instructions, P/N 315-033060 for
information when the total system load exceeds 12 amps.
The ZIC-8B plugs perpendicularly into one slot in the CC-5/CC-2 card-cage via two 96-
pin DIN connectors and can occupy any slot in the card cage. (Refer to Figure 4.)
Insert the ZIC-8B card into the card guides right side up (lettering on the front panel
is legible)

NOTE: The 24V current is dependent on the usage and wiring
type of each ZICCkt of the ZIC-8B. Listed below are the required
current draws for each zone usage and wiring type.

Slide the card in until the card edge connectors contact
the receptacles on the motherboard.
Verify that the DIN connectors of the card and the card-
cage aligned properly. The card can only plug in one
direction to the card cage, if it does not align, DO NOT
FORCE the card.
Place thumbs on the front panel adjacent to the captive
screws and gently apply even pressure on the card
until the connectors seat in the receptacles on the
motherboard.
Secure with the captive screws.
Power up the system and verify that the ZIC-8B power
LED turns ON.
