• Only qualified licensed electricians should install or service SPDs
• Hazardous voltages exist within SPDs
• SPDs should never be installed or serviced when energized
• Use appropriate safety precautions including Personal Protection Equipment
• Failure to follow these instructions can result in death, serious injury, and/or equipment damage.
• This manual shall be read in entirety prior to installing
Bonding and Grounding Hazard
Verify that the neutral conductor in the service entrance equipment is bonded to ground in accordance with the National
Electrical Code (NEC®) and all applicable codes.
Verify that the neutral terminal (XO) on the secondary side of distribution transformers are grounded to the system ground
in accordance with the NEC® and all applicable codes.
During installation into an electrical system the SPD must not be energized until the electrical system is completely installed,
inspected and tested. All conductors must be connected and functional including the neutral (if required). The voltage
rating of the SPD and system must be verified before energizing the SPD.
Failure to follow these guidelines can lead to abnormally high voltages at the SPD. This may cause the SPD to fail. The
warranty is voided if the SPD is incorrectly installed and/or if the neutral conductor in the service entrance equipment or
downstream of separately derived systems is not bonded to ground in accordance with the NEC®.
Do Not Hi-Pot Test SPDs
Any factory or on-site testing of power distribution equipment that exceeds normal operating voltage such as
high-potential insulation testing, or any other tests where the suppression components will be subjected to higher voltage
than their rated Maximum Continuous Operating Voltage (MCOV) must be conducted with the SPD disconnected from the
power source. For 4-wire systems, the neutral connection at the SPD must also be disconnected prior to performing high-
potential testing and then reconnected after test completion.
Failure to disconnect SPD and associated components during elevated voltage testing will damage the SPD and will void
the warranty.
