P5G-2UE
Neon Transformer Installation Guide
This Neon Transformer is Outdoor Type 2 Non-Weatherproof
INSTALLING the FRANCE P5G-2UE Series Neon Transformers (see installation diagrams on reverse):
HIGH VOLTAGE
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 attempts within approximately 10 seconds
to reset.)
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 may result in the transformer case
and any metal connected to it (enclosure, conduit, sign frame, etc.) to become
electrified if a secondary ground fault exists.

TROUBLESHOOTING a tripped P5G-2UE Series Transformer:
Service Switch does
not operate without
proper grounding of
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 (black 120 volt or red 277 volt) to the identified positive ("+") terminal. Connect the
neutral service wire (white) to the identified negative ("-") terminal.
Bond the service grounding wire (green or bare) to the sign enclosure per UL48 and the National Electrical Code.
Electrically connect another wire (green or bare) to this same service ground connection or to a terminal secured to a grounded
part of the sign enclosure. Connect the free end of this wire to the identified service ground ("G") terminal on the transformer.
(Alternatively, the transformer may be grounded by bonding its baseplate to the sign enclosure. Proper bonding may require the
removal of paint from the baseplate at the point of bonding.)
Improper grounding can result in electrifying all metal connected to the transformer during a secondary ground fault condition.
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.

Insure 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 identified
service ground (G) terminal is grounded via wire (or via the transformer mounting plate) 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.
