Step
The power cable and the grounding cable are
connected properly and they are free of rust.
If the power cable and the grounding cable are
not connected properly, please reconnect or
change them.
Step
Multimeter
Maintenance personnel measure the AC and DC
voltages of the input power with a multimeter and
keep a record.
1. The ZXA10 C320 uses –48/60 V power
supply. The equipment room should be
installed with
equipment to supply working power. The DC
power voltage is allowed to fluctuate between
–72 V and –38 V.
2. In order to ensure continuous working of the
ZXA10 C320 device in case of the mains
power failure, it is necessary to provide the
uninterrupted power supply measures, such
as diesel-electric set and storage battery.
3. DC power supply shall have
over-voltage/current protection and
indication.
When the test result is not in the standard range,
please check the input power supply timely and
make sure the backup power supply is in the
working status.
