This guide provides step-by-step instructions for installing the STXP Series Surge Protective Device (SPD) to protect your equipment from transient overvoltages.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Watertight fittings (if applicable)
- Confirm system compatibility
Verify that the system voltage and configuration match the SPD voltage and configuration before proceeding with the installation.
- Turn off power
Ensure all power supplying the equipment is turned off and confirm that the equipment and all sources are de-energized to prevent electrical shock.
- Determine mounting location
Select a mounting location for the SPD that is as close to the equipment as possible, ensuring that the LED status indicator will be visible.
- Mount the SPD
Securely mount the SPD according to the provided mounting guidelines, ensuring it is level and firmly attached.
- Make electrical connections
Connect the SPD to the electrical system as per the wiring diagram, ensuring leads are trimmed to the shortest length possible and avoiding sharp bends.
- Energize and verify operation
Turn the power back on and confirm the proper operation of the SPD by checking that the green LED status indicator is illuminated.
