Electrical Installation
Access to Wiring Chamber
The wiring chamber is accessed via the hinged door. Simply insert a flat-blade
screwdriver, as shown in Figure 5, and pry gently down to open. Select the best wiring
entrance and thread in the ½" x 14 NPSM conduit adapter (supplied), or the optional
M20 x 1.5 cable gland (page 11). The switch knockout will break loose with the final turn
of the conduit adapter or cable gland.

desired wiring terminal.
2. Twist the screwdriver blade in the slot to open the
terminal jaws; insert wire.
3. Hold wire in place and remove screwdriver.
Wiring
These switch models have redundant pairs of safety contacts, so they may be wired for
either single-channel or dual-channel output to a safety module or E-stop circuit. Monitor
contacts, in either case, may be wired as desired to an external alarm device.
Single-Channel Output: Wire contacts 21/22 or 41/42 together to the input of a safety
module or E-stop circuit.
Dual-Channel Output: Wire contacts 21/22 and 41/42 independently to the two safety
module inputs (see Figure 6).
