SAFETY PRECAUTIONS

ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Disconnect input power by removing
plug from receptacle before working
inside Inverter Arc 120 Allow machine
to sit for 5 minutes minimum to allow
the power capacitors to discharge before working
inside this equipment.
• Insulate yourself from the work and ground.
• Always wear dry insulating gloves.
• Always connect the Inverter Arc 120 to a power supply
grounded according to the National Electrical Code and
local codes.
SELECT SUITABLE LOCATION
This machine can operate in harsh environments.
However, it is important that simple preventative measures are
followed to assure long life and reliable operation:
• This machine must be located where there is free circulation
of clean air without restrictions for air movement to and from
the air vents. Do not cover the machine with paper, cloth or
rags when switched on.
• Dirt and dust that can be drawn into the machine should be
kept to a minimum.
• This machine has a protection rating of IP21S. Keep it dry
and do not place it on wet ground or in puddles. Do not use in
wet or damp locations. Store indoors.
• Locate the machine away from radio controlled machinery.
Normal operation may adversely affect the operation of
nearby radio controlled machinery, which may result in injury
or equipment damage. Read the section on electromagnetic
compatibility in this manual.
• Do not operate in areas with an ambient temperature greater
than 40°C.
STACKING
The Inverter Arc 120 cannot be stacked.
TILTING
Place the machine directly on a secure, level surface. Do not place
or operate this machine on a surface with an incline greater than
15° from horizontal. The machine may topple over if this
procedure is not followed.
HIGH FREQUENCY PROTECTION
Locate the Inverter Arc 120 away from radio controlled machinery.
The normal operation of the Inverter Arc 120 may adversely affect
the operation of RF controlled equipment, which may result in
bodily injury or damage to the equipment.
