Before wiring, verify the label for correct model number and
options. Switch off the power when checking.
Care must be taken to ensure that maximum voltage rating
specified on the label are not exceeded.
It is recommended that power of these units to be protected by
fuses or circuit breakers rated at the minimum value possible.
All units should be installed inside a suitably grounded metal
enclosure to prevent live parts being accessible from human
hands and metal tools.
All wiring must conform to appropriate standards of good
practice and local codes and regulations. Wiring must be
suitable for maximum voltage, current, and temperature rating of
the system.
Beware not to over-tighten the terminal screws. The torque should
not exceed 1N-m (8.9 Lb-in or 10.2 KgF-cm).
2 - 3 Wiring Precautions 2 - 3 Wiring Precautions
Unused control terminals should not be used as jumper points as
they may be internally connected, causing damage to the unit.
Verify that the ratings of the output devices and the inputs as
specified in Chapter 6 are not exceeded.
Except the thermocouple wiring, all wiring should use stranded
copper conductor with maximum gauge 18 AWG.
To remove the dust please use the dry cloth.
Protection impairment if used in a manner not specified by the
