Wiring
WARNINGS:
• Turn off power to the device before removing the cover in a hazardous area.
• All field wiring for AC models must have insulation suitable for at least 250 V.
• The DC input terminals shall be supplied from a source that provides electrical
isolation between the input and the output, in order to meet the applicable safety
requirements of IEC 61010-1.
• The equipment shall be protected by a fuse or circuit breaker of up to 16 A in the
building installation.
• A circuit breaker or switch in the building installation, marked as the disconnect
switch, shall be in close proximity to the equipment and within easy reach of the
operator.
• To avoid short-circuits, do not connect a load resistance with bare wires inside the
connection box.
Notes:
• AC and DC input circuits: min. 14 AWG (2.5 sq. mm) copper wire.
• Lay power cables separately from communication wiring.
• Recommended torque on terminal clamping screws: 0.5 to 0.6 N m (0.37 to 0.44 Lbf-ft).
