Connecting to a Power Source
1. Attach an insulated grounding wire, with a metal screw, to the marked grounding point.
2. Terminate the wire in an earthed grounding point.
CAUTION
The earth connection must not be removed unless all supply connections have been
disconnected.
Connecting to a Power Source
These switches support either AC or DC only dual power supplies.
DANGER
Before wiring the DC plug or connecting power to the switch, ensure that power to the feed lines
is turned off at the supply circuit breaker or disconnected from the power bus
Connecting DC Power
When using 20-60Vdc power, an external DC power supply must be connected to the DC power
connector on the left side of the front panel. DC input (DC source) must be isolated from AC mains
by reinforced insulation.
DANGER
Remove both power cords before servicing.
NOTE
To provide adequate circuit protection between the DC power supply and the switch, all intermediate
wiring and circuitry should be rated to carry a load at least two times the maximum rating for this
switch (see
NOTE
For a DC system, use a grounding wire of at least 18 American Wire Gauge (AWG). The 18 AWG wire
should be attached to an agency-approved crimp connector (provided on the chassis), and crimped
with the proper tool. The crimp connector should allow for securement to a ground screw on the
enclosure.
