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 4 zones exceeds 12 amps, a single PSC-12 cannot be used to
supply the ZIC-4A. Refer to the PSC-12 Installation Instructions, P/N 315-033060 for
information when the total system load exceeds 12 amps.
