6.3 Power Supply Wiring
Precautions
IMPORTANT
• All threaded parts must be treated with
waterproofing sealant. (A non-hardening
silicone group sealant is recommended.)
• Lay wiring as far as possible from electrical
noise sources such as large capacity motors
or power supplies.
• Remove the electrical connection dust cap
before wiring.
6.4 Selecting the Wiring
Materials
(a) Use stranded leadwires or cables which are
the same as or better than 600 V grade PVC
insulated wire (JIS C3307) or its equivalent.
(b) Use shield cables in areas that are susceptible
to electrical noise.
(c) In areas with higher or lower ambient
temperatures, use appropriate wires or cables.
(d) In environment where oils, solvents, corrosive
gases or liquids may be present, use wires or
cables that are resistant to such substances.
(e) It is recommended that crimp-on solderless
terminal lugs (for 4 mm screws) with insulating
sleeves be used for leadwire ends.
IMPORTANT
External powered type does not have a power
switch. Install a breaker on the power supply line
and turn the power ON/OFF.
6.5 Connection of the External
Power Source Terminal
For the external powered type, connect the power
supply wiring to + and − terminals. If the power
supply cable has shield wires, connect the cable
shield to the ground terminal.

Connection of External Power Source
Terminal
(Note) To protect against excessive surge, be sure to tighten the
ground terminal about 0.7 N∙m regardless of the shield
cable connection.
IMPORTANT
• Connecting with the commercial AC
power source will damage the device. Be
sure to use the DC power source in the
predetermined range.
• When connecting to the external power
source, be careful not to connect the polarity
reversely.
