■Wiring
Individual Wiring
The fasten tab terminal #250 is located at the back of
each unit. Connect the fasten receptacle to each
terminal: fault input, alarm output, and output
contact.
Wires should be 0.75mm2when wiring alarm output
for such items as buzzers and bells.
If only one wire is used, the maximum is limited to
1.25mm2.
Wiring Units
Wire the units together by plugging Connector Cap
“B”, which is extended from the back, to Connector
Plug “A” of the adjacent unit.
The number of units that can be wired together will
depend upon the lamp current and size of wires
used. Wire size for this unit is KIV0.75mm2. Refer to
the chart on right for the number of units.
●The maximum pitch dimensions for wire connecting
harnesses are as follows:
Model KFA-88 Width 100mm Height 50mm
Model KFA-98 Width 120mm Height 60mm
If further extension is desired, the special dimen-
sion specification will be needed.
●End terminal treatments are to be done on
Connector Cap “B”. Order the necessary number of
wire harnesses with plugs (KIV0.75mm2, length 2m)
separately. Plug “A” can be used by connecting to
the sub-panel when necessary.
