SELECT SUITABLE LOCATION
The POWER WAVE® R350 will operate in harsh environments. Even
so, it is important that simple preventative measures are followed in
order to assure long life and reliable operation.
• The machine must be located where there is free circulation of
clean air such that air movement in the back, out the sides and
bottom will not be restricted.
• Dirt and dust that can be drawn into the machine should be kept
to a minimum. The use of air filters on the air intake is not
recommended because normal air flow may be restricted. Failure
to observe these precautions can result in excessive operating
temperatures and nuisance shutdown.
• Keep machine dry. Shelter from rain and snow. Do not place on
wet ground or in puddles.
• Do not mount the POWER WAVE® R350 over combustible
surfaces. Where there is a combustible surface directly under
stationary or fixed electrical equipment, that surface shall be
covered with a steel plate at least .060" (1.6mm) thick, which
shall extend not less than 5.90" (150mm) beyond the equipment
on all sides.
This equipment is for industrial use only and it is not intended for
use in residential locations where the electrical power is provided by
the public low-voltage supply system. There can be potential diffi-
culties in residential locations due to conducted as well as radiated
radio-frequency disturbances. The EMC or RF classification of this
equipment is Class A.
