How to Install the STP230P07 Surge Protective Device

Installation guide for mounting and wiring the STP230P07 Surge-Trap® STP-50 and STP-75 series surge protective device.

Estimated time: 30m

Tools needed:

Screwdriver, Wire strippers

Supplies needed:

Mounting screws, Wire connectors

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Install Optional Micro-Switch

    If using the auxiliary micro-switch, install it according to its specific instructions.
