Notes of Caution for Installation
If a surge that exceeds rating enters the arrester,
it can short-circuit or damage the power line
and result in power outage. We therefore recommend
following preventive measures. |

Place an overcurrent protection device(OCPD) at A as shown
in the figure above to protect the power line where the
arrester will be installed, so that it can be quickly
isolated from the power supply should the arrester short-circuit.
If an OCPD cannot be installed at A, place it at B. When
wiring the arrester between the power line and the earth,
make sure that the arrester¡¯s grounding wire is connected
to a grounded case. If you cannot obtain sufficient grounding
resistance (class 2 grounding), install an OCPD or a thermoreactive
and other appropriate fuses at C.

When installing the arrester under direct sun ray or around
a heat-generating device, make sure that the ambient temperature
is within the operating range (-40¡ÆC~85¡ÆC) prior to installation.
If you must install the arrester in an area with potential
hazards such as dust, metallic granule, rain, dew, sea
salt or contaminants, place the arrester inside protective
housing. As for wiring, use pressure terminals and 600V
insulated wires with a cross-sectional area of 2mm2 or
greater. Make wiring as short and straight as you can.
For preventive measures against induced lightning surge
and make-and-break surge in electric facilities, use arresters
with large surge withstanding capabilities in GZ-¡à¡àH.

It is recommended that you use the following table for selecting
the arrester and the fuse rating current. You should also
review the specifications and conduct safety tests before
actual application. Please refer to the example in Fig. 1
regarding where the fuse should be placed. If the protected
device draws a large load current, or if the current exceeds
the following recommended rated fuse current value, install
a fuse and the arrestor in serial between power lines. |

For line-earth applications, the reference voltage must be 2.5
times (1.5 times in special cases) greater than the line-earth
voltage, and care must be taken so that it does not exceed the
maximum circuit voltage. An adequate value is around 50% (80%
in special cases) of the maximum voltage.
When conducting insulation resistance test (500V, 1000M¥Ø) and
withstanding voltage test (V1mA reference voltage or greater),
the leakage current might fail the test. Therefore, it should
be explained to the test administrator and the arrester must
be removed from the circuit before testing. |
