Chapter 3. MOUNTING AND WIRING
●
Mounting the alkaline batteries
• Remove the battery box cover and set 4 AA alkaline batteries in the holder. Then
attach the cover and tighten the screws
* If the
MCF
display does not turn on, try reinserting the batteries.
* Tightening torque: 1.3 -1.6 N·m.
After inserting the batteries, check the battery level on the device information dis-
play (page 29).

Wiring

Cautions for wiring
• Keep the
MCF
wiring (conduit) away from power wiring or high voltage wires.
• When connecting the connector, push the two parts together, and then tighten
the nut by hand to 0.4 to 0.6 N
•
m. Improper tightening can damage the
MCF
, or
lead to a loss of the IP65 seal, or allow the connector to come loose due to vibra-
tion.
• Do not pull the cable forcibly, and do not lift the
MCF
by the cable (pull-out
strength 40 N max., bending force 20 N max.) Do not bend the cable repetitively
or put a constant pulling stress on it.
• Do not rotate the cable where it joins the connector (see figure). Doing so might
rotate the connector, twisting and damaging the wires inside.
• Before wiring, be sure to remove the batteries.
• Keep water away from the cable and from the end of the connector while wiring.
• Be sure to check that the wiring is correct before turning the power on. Incorrect
wiring could cause damage or malfunction.
