• Install the V530-R160E/EP away from high-voltage devices and moving machinery to
allow safe access during operation and maintenance.
• Be sure to securely tighten the screws when mounting the V530-R160E/EP.
 Power Supply and Wiring Precautions
• Use the V530-R160E/EP with the power supply voltages specified in this manual.
• Use the wire and crimp terminals of the proper sizes as specified in this manual. Do
not connect the power supply wires by just twisting stranded wires and connecting
them directly to the terminals.
• Keep the power supply cable as short as possible (10 m maximum).
• Use a DC power supply with countermeasures against high-voltage spikes (safe
extra low-voltage circuits on the secondary side).

• Use an appropriate ground (100 Ω maximum).
• Use a grounding point as close as possible to the V530-R160E/EP and keep the
ground line as short as possible.
• Wire the V530-R160E/EP to the ground with a separate ground wire. To avoid
grounding problems, do not share the ground wiring with any other devices or ground
the V530-R160E/EP to the building's steel framing or plumbing.

Cooling vent
Before the V530-R160E/EP is shipped, a
protective label is attached to the top of the
V530-R160E/EP to cover the cooling vent.
This label prevents wire strands from falling
into the V530-R160E/EP during wiring. Do
not remove it until wiring is completed. The
label must be removed after wiring to allow
proper cooling during operation.
