CAUTION
• Be careful not to damage the internal electronic circuit when wiring. In addition, be careful not to apply
stresses on the 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.
• When stranded wires are used, prevent wires from contacting each other.
• Use the dedicated handling lever to wire.
