2.4.3 Wiring cover
l FLXA202
When grounding and power supply wiring are complete, double-check the wiring and the like,
and attach wiring cover 1 (Figure 2.11).
When attaching the wiring cover, align the protruding parts marked with squares in the gure to
the grooves.
If only the rst module is to be used, wire the detector to the rst module.
If the second module is to be used, wire the detector to the second module and attach wiring
cover 2 before wiring the rst module.
Then, wire the detector to the rst module.
Detector wiring is indicated in section 2.5.

After grounding and connecting the power supply, check the wiring and then close the wiring
cover 3 (Figure 2.4).
When closing the cover, engage the positions marked with ○ in Figure 2.4 and fasten the cover
with the screw at the position marked with ∆.
CAUTION
The screw in the area marked with ∆ should be tightened to a torque of 0.35 to 0.45 N•m.
If a second module is used, wire the sensor for the second module and attach the wiring cover
(refer to gure 2.12).
Then, wire the sensor for the rst module and attach the wiring cover (refer to gure 2.11).
The sensor wiring is shown in section 2.4.
NOTE
Be careful not to lose the wiring cover screws.
