ELETROMAGNETIC NEON TRANSFORMER
DO NOT ATTEMPT TO ALTER OR REPAIR THIS POWER SUPPLY. THIS MAY CAUSE INJURY AND WILL VOID WARRANTY.
HAZADOUS VOLTAGES WILL CAUSE SHOCK, BURN, OR DEATH. TURN OFF POWER BEFORE SERVICING.
SERVICING SHOULD BE PERFORMED ONLY BY QUALIFIED PERSONNEL.
1. All metal parts of the sign must be grounded. This power supply is a high frequency, high voltage device. Any
metal parts that are in the vicinity of the neon tubing, GTO wire, or the neon power supply may become energized
if left undergrounded. Ungrounded metal parts may impart an electrical shock.
2. Never ground any high voltage wiring of the sign system.
3. Do not feed the high voltage GTO leads through metallic conduit, but each GTO leads should be run in approved
sleeving.
4. Keep GTO wires at least 1 1/2 inches away from all surfaces and each other.
5. This power supply may be mounted directly inside the channel letter and/or mounted underneath the neon tubes
on the back wall of the channel letter.
6. Do not mount this power supply in a manner of allowing direct exposure to the weather or where it might
eventually stand in water.
7. Always mount two or more power supplies used in the same channel letter at least 12 inches apart.
8. This power supply may not be dimmed.
9. A miliampere meter should be used to properly load tubing to the power supply. Use the tube loading chart only
as a general reference. Do not attempt to overload the power supply. It will trip off if significantly overloaded.
1. Connect primary leads only to specified input voltage on the product label.
2. The power supply's green wire must be connected to the branch circuit safety ground. Assure the furnished safety
ground is traceable all the way back to the breaker panel.
3. Firmly connect the GTO leads to the tubing. Do not run GTO in metallic conduit. It may cause tripping or tube
dimming. Maintain at least 1 1/2 inch clearance between the GTO and any surface. Do not splice additional GTO to
exisiting output leads.
4. Keep all GTO leads as short as possible, especially those from the power supply to the first tubing electrodes.
5. Avoid crossing one GTO wire with another. If GTO wires must cross, cross at right angles using as large a clearance
as possible.
6. When passing a GTO cable through a metal partition, use as large a hole as possible. Use approved bushings to
center the wire in the partition. Failure to follow this procedure will result in premature failure of the GTO cable
and eventual power supply tripping.
7. It is best to wire border in a sign tubing in a sign near the electrical center of the sign.
1. Check the following;
- Electrical shorts or arcing from live high voltage sign components to ground.
- Excessive moisutre captured within or near sign. Make sure the sign is properly ventilated and water
does not directly enter the sign.
- Tubing too close to metal surfaces. A 1 1/2 inch clearance is recommended.
- Bad insulators or standoffs. Make sure they are free from corrosion and they provide a secure connection.
- Conductive debris between high voltage connections and conductive portions of the sign. Keep sign
free of dirt, insects etc.
- GTO leads too close to metallic sign parts. A 1 1/2 inch clearance is recommended.
- Power supplies mounted too close to each other in the same channel letter
(12 inch separation recommended)
- Poor grounding to the power supply.
2. Check for broken or otherwise degassed tubing
3. Are all sign connections robust?
