CAUTION

Be careful not to damage the internal electronic circuit when wiring. In addition, be careful not to
apply stresses on the gas detector when (overweight) cables are installed.

The power cables and signal cables must not be installed together with the motor power cables,
etc. When these cables must be installed together for unavoidable reasons, put the power cables
and signal cables in a metal conduit. The conduit must be connected to a grounding circuit.
