
Do not drop this instrument from high place. If you drop it and the display is cracked,
do not touch the liquid crystal or get it in your mouth. If the liquid crystal is touched,
wash it away at once.

Work under the electric outage condition when installing and wiring. It may cause
electric shock, electric burn injury or damage of the device.

When tapping or wiring, take care not to entering any foreign objects such as chips
and wire pieces into this instrument.

If the terminal wiring is pulled with a strong force, the terminals may detach. (Tensile
load: 39.2N or less)

When wiring in this instrument, be sure that it is done correctly by checking the
instrument
‘
s wiring diagram. Wrong wiring may cause failure of the instrument, a fire
or electric shock.

Use electrical wire sizes compatible with the rated current. Use of unsuitable sizes
may cause heat generation, which may lead to a fire.

Tighten the terminal screws with the specified torque and use the suitable pressure
connectors and suitable wire size. (Refer to page 90)

In order to prevent invasion of noise, do not bunch the control wires or communication
cables with the main circuit or power wire, or install them close to each other. The
distance between communicational signal lines, input signal lines and power lines, and
high voltage lines when running parallel to each other are shown below.
Conditions Length
Below 600V, or 600A power lines 30cm or more
Other power lines 60cm or more

Protective conductor terminals for mains circuits shall be at least equivalent in
current-carrying capacity to the mains supply terminals.

If the protective conductor terminals are also used for other bonding purposes, the
protective conductor shall be applied first and secured independently of other
connections.
