Figure 9: Crimping the Ring Terminal
Step 4
Slide the ground screw through the terminal.
Step 5
Insert the ground screw into the ground screw opening.
Step 6
Use a ratcheting torque screwdriver to tighten the ground screws and ring terminal to the switch front panel
to 3.5 in-lb (0.4 N-m). The torque must not exceed 3.5 in-lb (0.4 N-m).
Step 7
Attach the other end of the ground wire to a grounded, bare metal surface, such as a ground bus, a grounded
DIN rail, or a grounded bare rack.
Connecting the earth ground wire
Procedure
Step 1
Measure a single length of stranded copper wire long enough to connect the power supply to the earth ground.
The wire color might differ depending on the country that you are using it in.
For connections from the power supply to earth ground, use 10 to 12-AWG stranded copper wire.
Note
Step 2
Connect one end of the stranded copper wire to a grounded bare metal surface, such as a ground bus, a grounded
DIN rail, or a grounded bare rack.
Connect the other end of the wire to the grounding screw on the power supply. Only wire with insulation
should extend from the connection.
The position of the power supply may vary on different switch models.
Note
Step 3
Tighten the earth-ground wire connection screw.
Torque to 8 in.-lb, not to exceed 10 in-lb.
