Control wiring for features and options should be connected at the customer interface terminal block located
inside the SIAC-B.
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required.
Read and understand the following notes while planning and performing the installation:
•
Use Class 1 wiring methods (as defined by the NEC) for interface wiring from 30V to 600V. The wire
should be rated for 600V, 1A minimum. 12 AWG maximum wire size.
•
Use Class 2 wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire should be
rated for 24V, 1A minimum.
•
Use twisted-pair wires for each input and return or common.
•
All interface wiring and conduit is to be supplied by the customer.
•
Interface wiring can be installed using the inter-cabinet wiring access pass-through or by routing wiring
through conduit between cabinets.
•
Install the interface wiring in separate conduit from the power wiring.
