Connecting the Cable
Caution about connecting the cable
Electric
shock
Connect a grounding wire to a ground terminal. (class D
grounding)
There is fear of an electric shock.
A commercial power ordinarily has electrodes of a grounding
side and an un-grounding side apart from a grounding
electrode (ground). Be sure to confirm before connecting.
If connected in reverse, there is fear of the malfunction by noise or the
electric shock.
Important
The permissible voltage between the input electric cable of the UPS and
the ground is 230 VAC.
If the voltage more than 230 VAC is applied, the filter circuit of the input part may be
damaged.
The permissible input surge voltage of the UPS is 5kV peak (1.2
50µs).
However, if the model of the UPS is " -UC" , it is 2kVpeak (1.2
50µs).
If the surge voltage more than 5kV peak (
“
-UC
”
is 2kV peak) is applied, the filter
circuit of the input part may be damaged.
The input voltage of the UPS is 85 to 138 VAC.
When input voltage is different from the rated specification (200 VAC, etc.), install a
transformer at the outside of the UPS to convert voltage. If the voltage more than the
range of the input voltage is applied, the UPS may be damaged.
Connect the UPS to an input power supply within the range of the rated
input voltage of the connection device.
At the bypass operation, the input voltage of the UPS is outputted to the connection
device directly. If the voltage more than the range of the rated input voltage of the
connection device is applied, the connection device may be damaged.
Do not apply single-line grounding on the output side.
Between the input and output of the UPS is not insulated. Therefore, do not apply
single-line grounding on the output side.
There is a possibility of becoming the cause of the trouble by noise or the failure.
