•
Use Class 2 wiring methods (as defined by NEC Article 725) 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.
•
