SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Have an electrician install and
service this equipment.
• Turn the input power off at the
fuse box before working on
equipment.
• Do not touch electrically hot parts.
• Be sure to discharge capacitors with the proce-
dure outlined in the Maintenance Section of this
manual before working in that area of the
equipment.
-----------------------------------------------------------------------
SELECT SUITABLE LOCATION
The ES 275i 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 cir-
culation of clean air such that air movement in the
back and out the front will not be restricted.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. 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 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 .06”(1.6mm) thick, which shall extend not
less than 5.90”(150mm) beyond the equipment on
all sides.
-----------------------------------------------------------------------

STACKING

ES 275i’s cannot be stacked.

TILTING

Place the machine directly on a secure, level surface.
The machine may topple over if this procedure is not
followed.
HIGH FREQUENCY PROTECTION
Locate the ES 275i away from radio controlled
machinery.
The normal operation of the ES 275i may adverse-
ly affect the operation of RF controlled equipment,
which may result in bodily injury or damage to the
equipment.
