Wiring covers

FLXA202
NOTE
Wiring covers are required intrinsic safety and Type n (Type is -C*, -DB, -DE). In the case of other
types, the cover is not attached to the FLXA202.
When two sensor modules are used, the upper-level module is for input 1 and the lower-level
module is for input 2. For ease of installation, first wire input 2 sensor on the lower-level module,
and attach the wiring cover 1; then wire input 1 sensor on the upper-level module and replace the
module wiring cover 2.
