Estimated time: 30m
Tools needed:
Screwdriver, Wire strippers
Supplies needed:
Mounting screws, Wire connectors
- Verify System Compatibility
Confirm that the system voltage and configuration match the SPD's voltage and configuration. Refer to the product's nameplate or datasheet for specific values.
- De-energize Power Sources
Turn off all power supplying the equipment. Verify that all power sources are de-energized before proceeding. DANGER: Failure to do so can result in death, serious injury, or equipment damage.
- Mount the SPD
Mount the SPD onto a 35mm DIN-rail or top-hat rail. Hook the line side over the rail and push the load side until the spring-loaded mounting clip clicks into place.
- Make Electrical Connections
Connect the electrical wiring according to the appropriate wiring diagram for your system configuration. Ensure interconnecting wires are kept to a minimum length and avoid looping or twisting conductors. Refer to the nameplate or datasheet for wire size and torque specifications.
- Install Optional Micro-Switch
If using the auxiliary micro-switch, install it according to its specific instructions.
