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 figure to
the grooves.
If only the first module is to be used, wire the detector to the first module.
If the second module is to be used, wire the detector to the second module and attach wiring
cover 2 before wiring the first module.
Then, wire the detector to the first module.
Detector wiring is indicated in section 2.5.

If a second module is used, wire the sensor for the second module and attach the wiring cover
(refer to figure 2.12).
Then, wire the sensor for the first module and attach the wiring cover (refer to figure 2.11).
The sensor wiring is shown in section 2.4.
