Install the Switch Chapter 1
7. Use a ratcheting torque screwdriver to tighten the ground screw and ring
terminal lug to the switch front panel to 0.96 N•m (8.5 lb•in).
8. Attach the other end of the ground wire to a grounded bare-metal surface,
such as a ground bus, or a grounded DIN rail.
Wire the DC Power Source
for the Switch
Follow these steps to wire DC power to the switch.
1. Locate the power and alarm relay connector and identify the positive and
return DC power connections.
The positive DC power connection is labeled V, and the negative DC
power connection is the adjacent connection labeled RT. Connections
labeled A are used for the alarm relay connectors.
2. Measure a length of 0.82…0.52 mm
2
(18…20 AWG) copper wire long
enough to connect to the DC power source.
3. Using an 18-gauge wire-stripping tool, strip each of the two wires to
6.3 mm (0.25 in.) ± 0.5 mm (0.02 in.).
Do not strip more than 6.8 mm (0.27 in.) of insulation from the wire.
Stripping more than the recommended amount of wire can leave exposed
wire from the connector after installation.
WARNING: Before performing any of the following procedures, make sure that
power is removed from the DC circuit or the area is nonhazardous before
proceeding.
WARNING: To comply with the CE Low Voltage Directive (LVD), this equipment
must be powered from a source compliant with the safety extra low voltage
(SELV) or protected extra low voltage (PELV).
To comply with UL restrictions, this equipment must be powered from a source
compliant with Class 2 or Limited Voltage/Current.
