TROUBLESHOOTING a tripped P8G Series Transformer:
Securely mount the transformer in an approved metallic enclosure (transformer can, raceway, sign body, etc.).
Run the service wires through conduit into approved enclosure.
Connect the line (or "hot") service wire to the black or red transformer lead wire. Connect the neutral service wire
white transformer lead wire.
Bond the service grounding wire (green or bare) to the sign enclosure per UL48 and the National Electrical Code.
Electrically connect green transformer lead wire to this same service ground connection or to a terminal secured to
a grounded part of the sign enclosure. The transformer may be grounded by connecting a bonding wire to the G
terminal.
Run GTO wires from the first neon tubing electrodes through separate conduit, raceway, sign body, etc. to each
transformer secondary high voltage bushing. (These wires should be kept as short as possible, but may not exceed
20 feet.)
Make sure to securely tighten all service and high voltage output terminal nuts.
Replace transformer can box cover if applicable.

Neon Transformer Installation Guide
This Neon Transformer is suitable for use only in dry and damp locations and is designated Outdoor
Non-Weatherproof Dry or Damp Type 2.

Ensure the line and neutral service wires are connected properly and are not reversed. Black or red wires should
be hot, while white wires should be neutral. The transformer will never energize the tubing if the line and neutral
wires are reversed. If the supply wires appear to be connected properly, the polarity of the service wires themselves
may be reversed (i.e. the black or red wire is actually the neutral and the white wire is actually the hot wire).
Verify the service grounding wire is actually ground and is properly bonded to the sign enclosure. Verify the transformers
green lead wire or identified service ground (G) terminal is grounded to the sign enclosure.
Check for excessive leakage currents caused by moisture within or on the sign, tubing installed too close to metal,
contaminated insulators or standoffs, or conductive debris such as insects, dirt, etc. between live high voltage sign
components and ground.
Check for electrical shorts or arcs from live high voltage sign components to ground. To help locate the source of
such faults, the Secondary-Circuit Ground-Fault Protection (SCGFP) may be placed in Service mode. To activate
service mode, momentarily depress the small pushbutton on the end panel of the transformer. While in service mode,
power is applied and the SCGFP feature will be disabled for approximately 29 minutes, after which the transformer
will return to normal operation. Return to normal operation at any time by removing and reapplying service power
or by pressing the service button again.
Warning: During Service Mode, no protection against an abnormal arc-
induced electrical fire exists.
No protection against electrical shock exists during any operational mode.
After the source of any fault is removed, the transformer can be reset by removing and reapplying supply power.
u
Remove primary power before servicing the sign or transformer in any way.
Secondary-Circuit Ground-Fault Protected (SCGFP) transformers will NOT provide
protection against electrical shock. Potentially hazardous high voltage can be
present.
Service and/or installation should only be performed by qualified personnel.
Do not assume power is removed from transformer if ground fault trip occurs (the
transformer will automatically make 3 reset attempts within approximately 10
seconds.)
Installation must be in total compliance with the National Electrical Code®, the
requirements of Underwriters Laboratories and applicable local codes.

Failure to properly ground this transformer will result in the transformer case
and any metal connected to it (enclosure, conduit, sign frame, etc.)becoming
electrified when a secondary ground fault exists.
