3. SETUP
AC Power
The 4BAR™ Flex has an auto-
ranging power supply and it can work with an input
voltage range of 100~240 VAC, 50/60 Hz.
To determine the product’s power requirements (circuit breaker, power outlet, and
wiring), use the current value listed on the label affixed to the product’s back panel, or
refer to the product’s Technical Specifications. The listed current rating indicates the
product’s average current draw under normal conditions.
Always connect the product to a protected circuit
(circuit breaker or fuse). Make
sure the product has
an appropriate electrical ground to avoid the risk of
electrocution or fire.
Never connect the product to
a rheostat (variable resistor) or dimmer circuit, even
if the rheostat or dimmer channel serves only as a 0% to 100% switch.
Fuse

Disconnect the product from the power outlet before replacing the fuse.
