The mercury vapor ballast wiring diagram is the blueprint for the ballast circuitry, including the input supply voltage and grounding methods. A ground connection must be made to all ballasts to avoid shock hazard, personal injury or damage to the luminaire or installation. Mercury vapor Ballast installations and groundings should be made in accordance with all applicable government codes and regulations where required.
HID lamp servicing requires close attention to safety. Working
with electrical equipment at significant heights can be
dangerous if proper preparations and precautions are not
taken. The following is a general safety checklist. Always
follow the exact safety procedures outlined by your company.
1. Park the lift truck at the safest possible location at the
work site. Set up safety cones to direct traffic around the
2. Before beginning, check the lift bucket of the truck to
make certain it is secure. The pivot point mounting should
be tight with no cracks or breaks. Also make certain the
bucket is equipped with a fiberglass liner and that the liner
is in good shape with no cracks or breaks. Although not a
common problem, lamps have been known to shatter due to
operational problems or when being turned into or out of the
3. Make sure the boom strap is in place and secure.
4. Make certain the lanyard is in good shape, fastened and
secure. The safety belt also must be in good condition.
5. Always strap on the safety belt before raising the bucket.
Putting the safety belt on should be the first thing you do
after stepping into the bucket.
6. Always use a properly secured safety belt when working
7. Always wear a hard hat when servicing a luminaire in the
8. Wear work boots with non-slip insulating soles.
9. Always wear high-voltage gloves when servicing and
replacing luminaires. Inspect the gloves at the start of each
workday for holes and tears. Replace damaged gloves immediately.
Keep your high-voltage gloves in the glove bag
located in the bucket so they will always be available when
HID Ballast Wiring Diagrams
Ballast Wiring Diagrams for HID ballast kits including Metal Halide and High Pressure Sodium Lighting ballasts. Most magnetic HID ballasts are multi-tap, meaning they can be connected to several different voltages.
Here we display wiring diagrams for metal halide (probe start), mercury vapor ballast and high pressure sodium HID ballast kits. Most magnetic HID ballasts are multi-tap, meaning they can be connected to several different voltages. Here we display wiring diagrams for metal halide (probe start), metal halide (pulse start) and high pressure sodium HID ballast kits.
