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.

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.
