CAUTION
LOSS OF SURGE PROTECTION
· During installation into an electrical system, SPD’s must not be energized until the electrical system
is completely installed, inspected, and tested. All conductors must be connected and functional,
including the neutral. The voltage rating of the device and system must always be verified before
energizing the surge protective device.
· Any factory or on-site testing of power distribution equipment that exceeds the normal operating
voltage, such as high-potential insulation testing, or any other tests where the suppression
components will be subjected to voltages higher than their rated turn-on voltage must be performed
with the suppressor disconnected from the power source. The neutral connection at the SPD must
also be disconnected prior to performing high-potential testing and then reconnected upon
completion of the test.
