See Subsec. 6.2.3.
(4)Power supply cable
CP1/CP2 connector
1 2 3
Y +24 V 0 V
X +24 V 0 V
D 24 VDC is supplied via a Y–connector. Provided the power supply
has sufficient capacity, power can be supplied to another device
with the X–side as output. (On the other hand, the X–connector can
be used for input, and the Y–connector, for output.)
D Power must be supplied to both CP1 and CP2.
D Cable–side connector specification
Y–connector: A63L–0001–0460#3LKY (AMP Japan, 2–178288–3)
X–connector: A63L–0001–0460#3LKX (AMP Japan, 1–178288–3)
Contact: A63L–0001–0456#BS (AMP Japan, 175218–5)
Ordering information: Y + 3 contacts: A02B–0120–K323
X + 3 contacts: A02B–0120–K324
D Cable material: Vinyl–insulated electrical wire AWG20–16
D Cable length: Determine the length of the cable such that the
supplied voltage at the receiving end satisfies the requirements,
because the voltage may fluctuate and drop as a result of the
resistance of the cable conductor.
(5)Frame grounding
Ground the frame of the unit using a wire having a cross section of at
least 5.5 m
2
(class 3 or higher). An M4 frame ground terminal is
provided.
