WARNING - - IMPORTANT - - PLEASE READ - - WARNING
INSTALLATION - BONDING AND GROUNDING HAZARD:
service entrance equipment is bonded to ground in accordance with the National Electrical Code and verify
the neutral terminals (XO) on the secondary side of distribution transformers are grounded to the system
ground in accordance with NEC and all applicable codes.
During installation into an electrical system, the TPS must not be energized until the electrical sys-
tem is completely installed, inspected and tested. All conductors must be connected and functional
including the neutral (if required). The voltage rating of the device and system must always be verified
before energizing the TPS.
Failure to follow these guidelines can lead to abnormally high voltage at the TPS. This may cause the TPS to
become inoperative. The warranty is voided if this device is incorrectly installed and/or if neutral
conductor in the service entrance equipment is not bonded to ground in accordance with the
National Electrical Code (NEC).
TESTING - HIGH VOLTAGE TESTING - DO NOT HI-POT TEST:
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 conducted with the suppressor disconnected from the power source.
For 4-wire TPS devices, the neutral connection at the TPS must also be disconnected prior to performing
high-potential testing and then reconnected upon completion of the test.
Failure to disconnect this surge suppression device and its associated suppression components during
elevated voltage testing will damage suppression components and/or other electronic components, and
will void the warranty.
