(1) Reserve sufficient space for maintenance.
Design the system so that it allows required space for maintenance.
7. Common Precautions for wiring and cables
Warning
(1) The power supply to the product must always be switched off before adjusting, mounting,
inspection or wiring is done.
An electric shock, malfunction, and breakage can result.
(2) Never disassemble the cable. Never use cables other than specified.
(3) Never connect or disconnect a connector and cable when it is energized.
Caution
(1) Do not apply any voltage to the terminals outside the specified levels in the operation
manual.
(2) Wire the connectors securely.
Check what the connector should be wired with and its direction.
(3) Take appropriate measures against noise.
Noise in a signal line may cause malfunction. As a countermeasure, separate high voltage and low
voltage cables, and keep the wire lengths as short as possible, etc.
(4) Do not route the wires and the cables together with power or high voltage cables.
It can cause malfunction to the product due to noise and surge voltage interference from power and
high voltage cables to the signal line. Route the wires of the Card Motor separately from power or
high voltage cables.
(5) Take care that the cables are not caught by the actuator movements.
(6) Operate the Card Motor with the cables secured. Avoid bending and fixing the cables with the
minimum bending radius or less. Avoid bending the cables at the cable entries.
(7) Avoid twisting, folding, rotating or applying external forces to the cables. Also avoid
operating at the minimum bending radius or less.
Otherwise it can result in electric shock, breakage or contact failure of the cable or loss of control of
the product.
(8) Confirm insulation performance of the wiring.
Insulation damage, interference with other circuits, poor insulation between
terminals etc. could
induce excessive voltage or current to the controller or its peripheral devices and damage them.
The controller or its peripheral devices could be damaged due to the excessive voltage or
current.
