Power supply voltage
A power supply voltage is required for
operation of the UMG604. The type and
amount of power supply voltage required is
noted on the rating plate.
Before applying the power supply voltage,
ensure that the voltage and frequency match
the information given on the rating plate!
The connection cables for the power supply
voltage must be fused with a UL listed fuse
(6A type C).
-
A disconnector or circuit-breaker
must be provided for the power
supply voltage in the building
installation.
- The disconnector must be installed
near the device and must be easy
for the user to reach.
-
The switch must be labelled as
a disconnecting device for this
device.
-
Voltages which are above the
allowable voltage range can destroy
the device.
