2.2.1 Connecting the AC Power Supply
WARNING
Check the following points before connecting the unit to a power
supply. Take care never to exceed the power supply ratings given
below, to avoid the risk of electric shock and damage to the unit.
1. Power supply matches Rated supply voltage (100 to 240 V AC:
Voltage fluctuations of
10% from the rated supply voltage are
taken into account.) and rated supply frequency (50/60 Hz).
2. The AC power switch of the 8730-10, 8731-10 is set to OFF.
3. Use only the supplied AC power cord.
When supplying power with an inverter or an uninterruptible power
supply (UPS), use a device that complies with the following
conditions. To avoid the risk of electric shock and damage to the
unit, do not use devices that have a voltage frequency outside the
specified range, or that output square waves.
1. Voltage: 100 V to 240 V AC
2. Power frequency: 50/60 Hz
3. Sine wave output (Do not use devices that have an unstable
output, even if the output is sinusoidal.)
The 8730-10, 8731-10 has no protective ground terminal, but is
intended to be connected to a ground wire via the grounded three-
core power cord supplied. In order to avoid electric shock
accidents, be sure to connect the grounded three-core power cord
supplied to a power supply socket one of whose terminals is
properly grounded.
NOTE
The fuse is incorporated in power supply. It is not user-replaceable. If a problem is
found, contact your dealer or Hioki representative.
2.2 Power Supply and Ground Connections
