Operating Precautions
15
When connecting measurement cables to a Wireless Voltage/Temp Unit or
Wireless Universal Unit
Connection Precautions
Do not leave the Unit connected to test objects in environments
where a voltage surge might exceed the dielectric withstand voltage.
Doing so could result in damage to the measurement units, bodily
injury or fatal accident.
• To avoid electric shock or a short-circuit accident, disconnect
power to the measurement line before turning on the measurement
unit.
• To avoid shock and short circuits, turn off all power before connect-
ing measurement cables.
• Do not connect a cable to the measurement units while it is con-
nected to the object to be measured. Otherwise, an electric shock
accident may occur.
• To avoid short-circuit accidents, make certain that connections are
secure.
• To avoid electric shock and short-circuit accidents, always close
the analog input terminal cover and tighten the screws.
• To avoid electric shock, use the recommended wire type to connect
to the current input terminals, or otherwise ensure that the wire
used has sufficient current handling capacity and insulation.
• Measurement units are not drip-proof and should be installed so
that water or other liquids cannot flow down measurement cables
and enter the unit enclosure via the terminal block. One way to do
so is to orient the unit so that the measurement cables are lower
than the unit.
