4.3 Installations of Cable Connectors:
4.3.1
When field installing connectors, use the pro-
vided conductive ground metal plates.
4.3.2
Align the ground plate inside the enclosure so
that the threaded hole is centered with the
hole in the enclosure.
4.3.3
Insert the connector through the sealing ring
and screw the connector into the ground plate
inside the enclosure.
4.3.4
Tighten the connector so that the sealing ring
is pressed evenly against the enclosure.
4.3.5
Tighten the set screw on the metal plate to
prevent the connector from loosening.
4.3.6
In case of through wiring the two ground
plates need to be bonded with jumper wire
since the FRP enclosures are non-metallic.
6.
Connect conductors to the component termi-
nals (capacity: 12 AWG or 2.5 mm
2 ).
Conductor insulation must reach to the termi-
nals. Tighten all terminals to 18 in.-lb. (includ-
ing those unused) and secure components on
mounting rail.
7.
Perform a continuity check.
8.
Replace the enclosure cover ensuring
alignment between actuators and internal
components. Actuate the switch and/or
pushbuttons to check for free operation.
9.
Energize the supply circuit and test the
system.
