2. Installatio n
1.Before installation, please make sure the AC input voltage is correct.
a.The AC input voltage of APS-9301/9501 is either 115V or 230V,
which can be selected. The select switch is located on the rear panel.
b. The AC input voltage of APS-9102 is fixed either at 115V or 230V,
For safety reason,Do not make any change by you own to avoid
damaging the instrument.
2.Before plugs input power cord to the suitable outlet or connects the
input wires, please make sure all the APS-9301/9501/9102’s breakers
are turned off. It will avoid the unnecessary accident or damage to
APS-9301/9501/9102.
3.Plugs the input power cord to the suitable outlet or connects the input
wires/cable to the input terminal block which is located inside panel of
APS-9301/9501/9102. Please make sure the connections are very tight
which may avoid some problem happening.
4.Please make sure the input tolerance of this APS-9301/9501/9102 is
within ±15% of rated voltage (see figure 1)

Remark:
1. The ambient temperature of “Permissible Current” is at
40℃, the withstanding temperature of conductor is at
105℃ according to the condition of the distributed
single wire.
2. The permissible current listed as above is suggested to
be used under 70%.
3. When the current value exceeds above suggestive list,
can select more wires used in parallel according to
above list.
