1.
Ensure no voltage is present on the signal wires.
2.
Mount the CB-37F-HVD onto the DIN rail.
3.
Prepare the 12–30 AWG signal wire by stripping the insulation no
more than 4.0 mm (0.16 in.).
4.
Insert the stripped ends of the signal wires into the screw terminals.
Make sure no bare wire extends from the terminal.
5.
Tighten the screws to a torque of 0.3 N · m (2.7 lb - in.).
6.
Tighten the zip ties securely around the signal wires for strain relief.
For additional strain relief, you should securely tighten additional zip
ties around signal wires from the top row of screw terminals.
Note
To replace the zip ties, remove one of the end pieces from the CB-37F-HVD. Slide
the PCB out and guide the zip tie through the holes on the PCB. Replace the PCB, end
piece, and screws.
