CAUTION
The AC electrical service where the step-down transformer is connected should be
close to the unit and easily accessible.
Please use only UL-marked mains cable, (e.g. the mains cable of your equipment),
to connect the step-down transformer to the AC outlet.
Please use only UL-marked power cables to connect any equipment to the step-
down transformer.
Do not unplug the unit from AC power during operation, as this will disconnect the
protective ground insulation.
Do not use an improper size power cord as it may cause damage to your
equipment and cause fire hazards.
Make sure everything is turned off and disconnected completely before conducting
any maintenance, repairs or shipment.
Installation environment should be in a temperature and humidity controlled
indoor area free of conductive contaminants. Do not install this step-down
transformer where excessive moisture or heat is present (Please see specifications
for acceptable temperature and humidity range).
Never install a step-down transformer, or associated wiring or equipment, during a
lightning storm.
Do not work alone under hazardous conditions.
Input circuit breaker must be “OFF” during the building installation.
Only qualified maintenance personnel should perform this task.
Before connecting to the step-down transformer, check that the input voltage into
the step-down transformer is within specifications.
DO NOT INSTALL THE STEP-DOWN TRANSFORMER WHERE IT WOULD BE
EXPOSED TO DIRECT SUNLIGHT OR NEAR A STRONG HEAT SOURCE!
DO NOT BLOCK OFF VENTILATION OPENINGS AROUND THE HOUSING!
DO NOT CONNECT DOMESTIC APPLIANCES SUCH AS HAIR DRYERS TO STEP-
