14.3 CONNECTION DIAGRAMS

Caution: Electrical devices connected to the controller must meet local electrical codes and be within
!
the voltage limits specified in this manual.
!
Caution: All field wiring must be properly fused and sized in accordance with local codes.
Caution: Wires must be installed such that the connection does not rely on the structural integrity of
!
the wire insulation and no more than one conductor is terminated in a single terminal.
