Section 1 – SR-2 Safety Information
ELECTRICAL HAZARDS
High Voltage
Model 50 units with optional Electric Standby utilize
460, 380 or 230 volt, 3 phase AC power any time the
unit is operating in Electric mode. This voltage
potential is also present any time the unit is
connected to standby power. Extreme care must be
used when working on the unit, as these voltages
are capable of causing serious injury or death.
1. When working on high voltage circuits, do not
make any rapid movements. Unplanned
movements can cause contact with high voltage.
2. Use tools with insulated handles that are in good
condition. Never hold metal tools in your hand if
exposed high voltage conductors are within
reach.
3. Treat all wires as high voltage wires.
4. Never work alone on high voltage circuits.
Another person should be nearby in case of
accident.
High Voltage First Aid
Immediate action must be taken after a person has
received an electrical shock. Medical attention
should be summoned as soon as possible.
The source of electricity must be immediately
removed, either by shutting down the power or
removing the victim from the source. If the victim
must be removed from a live circuit, pull the victim
off with a non-conductive material. Use the victim's
clothing, a rope, wood or your belt. After separating
the victim from the power source, immediately check
for pulse and respiration. If a pulse is not present,
start CPR (Cardio-Pulmonary Resuscitation)
immediately. If a pulse is present, respiration may
be restored by mouth to mouth resuscitation. Obtain
emergency medical assistance as soon as possible.
Low Voltage
Control circuits are typically 12 volts dc. This
voltage potential is not considered dangerous, but
the large amount of current available can cause
severe burns if shorted to ground.
Do not wear jewelry, watches or rings when working
on the unit. Severe burns can occur if these items
contact an electrical circuit.
