Safety Instructions
14
• 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.
Low Voltage
Control circuits are low voltage (24 Vac and 12
Vdc). This voltage potential is not considered
dangerous. Large amount of current available
(over 30 amperes) can cause severe burns if
shorted to ground. Do not wear jewelry, watch or
rings. These items can shortcut electrical circuits
and cause severe burns to the wearer.
Electrostatic Discharge
Precautions
Precautions must be taken to prevent electrostatic
discharge while servicing the MP-3000a
microprocessor and related components. The risk
of significant damage to the electronic
components of the unit is possible if these
precautionary measures are not followed. The
primary risk potential results from the failure to
wear adequate electrostatic discharge preventive
equipment when handling and servicing the
controller. The second cause results from electric
welding on the unit and container chassis without
taking precautionary steps.
Electrostatic Discharge and the
Controller
You must avoid electrostatic discharges when
servicing the controller. Solid-state integrated
circuit components can be severely damaged or
destroyed with less than a small spark from a
finger to metal object. You must rigidly adhere to
the following statements when servicing these
units. This will avoid controller damage or
destruction.
• Disconnect all power to the unit.
• Avoid wearing clothing that generates static
electricity (wool, nylon, polyester, etc.).
• Do wear a static discharge wrist strap (refer to
Tool Catalog) with the lead end connected to
the controller's ground terminal. These straps
