Electrical Precautions
The possibility of serious or fatal injury from electrical shock exists when servicing a refrigeration unit.
Extreme care must be used when working with a refrigeration unit that is connected to its power source.
Extreme care must be used even if the unit is not running. Lethal voltage potentials can exist at the unit
power cord, inside the control box, inside any high voltage junction box, at the motors and within the
wiring harnesses.
Precautions
In general disconnect the units power cord before repairing or changing any electrical
components.
Note that even though the controller is turned off, one of the phases is still live and represents
a potential danger of electrocution
Where turning of the unit is not possible (for example at voltage measuring or troubleshooting), follow
safety precautions below.
• Turn the unit On/Off switch to Off before connecting or disconnecting the unit power plug. Never
attempt to stop the unit by disconnecting the power plug.
• Be certain the unit power plug is clean and dry before connecting it to a power source.
• Use tools with insulated handles. Use tools that are in good condition. Never hold metal tools in your
hand if exposed, energized conductors are within reach.
• Do not make any rapid moves when working with high voltage circuits. Do not grab a falling tool or
other object. People do not contact high voltage wires on purpose. It occurs from an unplanned
movement.
• Treat all wires and connections as high voltage until ammeter and wiring diagram show otherwise.
• Never work alone on high voltage circuits on the refrigeration unit. Another person should always be
standing by in the event of an accident to shut off the refrigeration unit and to aid a victim.
• Have electrically insulated gloves, cable cutters and safety glasses available in the immediate vicinity
in the event of an accident.
First Aid
IMMEDIATE action must be initiated after a person has received an electrical shock. Obtain immediate
medical assistance.
The source of shock must be immediately removed. Shut down the power or remove the victim from the
source. If it is not possible to shut off the power, the wire should be cut with either an insulated instrument
(e.g., a wooden handled axe or cable cutters with heavy insulated handles). A rescuer wearing electrically
insulated gloves and safety glasses could also cut the wire. Do not look at the wire while it is being cut.
The ensuing flash can cause burns and blindness.
Pull the victim off with a non-conductive material if the victim has to be removed from a live circuit. Use
the victim’s coat, a rope, wood, or loop your belt around the victim’s leg or arm and pull the victim off.
Do not touch the victim. You can receive a shock from current flowing through the victim’s body.
Check immediately for the presence of a pulse and respiration after separating the victim from power
source. If a pulse is not present, start CPR (Cardio Pulmonary Resuscitation) and call for emergency
medical assistance. Respiration may also be restored by using mouth-to-mouth resuscitation.
