Wiring
Wire in accordance with NFPA 72 and CAN/ULC-S524. Be
sure to observe the polarity of the terminals on the terminal
block as shown in the diagram.
Break the wire run at each terminal. Do not loop signaling
circuit field wires around terminals.
Refer to the applicable technical reference manual for
application diagrams.
Note: Shielded wire is required only in environments with very
high electrical noise. When you use shielded cable, follow
these recommendations
:
• Shield connection to and from the base must be
continuous and must be insulated from ground. Insulate
the shield using tape.
• For Class B wiring, there is no shield connection to ground
at the last device.
