CAUTION
•
Be careful not to damage the internal electronic circuit when wiring. In addition, be careful to provide
appropriate strain relief when using cables for wiring.
•
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.
