Safety Precautions

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR
ARC FLASH
Refer to nameplate for ratings and voltages.
This equipment must only be installed and
serviced by qualified electrical personnel.
Follow all requirements in NFPA 70E and CSA 462
for safe work practice and personal protective
equipment (PPE).
Turn off all power supplying this equipment
before working on or inside equipment.
Always use a properly rated voltage sensing device
to confirm power is off.
Replace all devices, doors, and covers before
turning on power to this equipment.
Failure to follow these instructions will result
in death or serious injury.
1. Do not lift or move a transformer without proper
equipment and experienced personnel. Lifting provisions
are provided inside of the enclosure on the core/coil only.
Always use lifting provisions provided by the manufacturer.
DO NOT LIFT THE TRANSFORMER BY THE ENCLOSURE.
Rolling and skidding are recommended on transformers
with a pre-ordered skidding base (see figure 9).
2. Do not off-load the transformer until a full inspection has
been completed.
3. Only use terminals for electrical connections. Flexible
connectors are recommended for bus connections. The
transformer terminals are not designed to support the
weight of line or load cable. Uni-strut supports can
be added in the field providing proper clearances are
maintained.
4. Cover the core and coil with a suitable protective drop
cloth if there is drilling, grinding, or painting to be done.
5. Connections should only be made in accordance with the
nameplate diagram or connection drawings.
6. Make sure all power (including back-fed control, shared
neutral and capacitor charge) is disconnected and all
windings are grounded before attempting any work on
the transformer or inside the control box.
7. Make certain all ground connections, line terminals and
selected tap connections are complete and tightened
before energizing the transformer.
8. Do not attempt to change any primary or secondary
connections or taps while the transformer is energized.
9. Do not tamper with control panels, alarms, interlocks, or
control circuits.
10. Do not adjust or remove any accessories or cover plates
while the transformer is energized.
11. No supply cables (including shielded cables) should come
in contact with the core or coil or any live part except
the terminal that it is intended for. Ensure that minimum
clearances are maintained. (refer to Field Testing section)
12. This equipment must only be installed and serviced by
qualified electrical personnel.
13. Follow all requirements in NFPA 70E and CSA 462 for safe
work practice and personal protective equipment (PPE).
14. Replace all devices, doors, and covers before turning on
power to this equipment.
15. You are not allowed to perform any modification to
the equipment (as this may affect warranty and cause a
hazardous situation) without HPS's prior authorization.
