NOTE: Minimum loop power supply voltage required:
8.5V + (Max - Customer - Equipment - Drop) +
(Wiring - IR - Drop)
CAUTION:
When reassembling the faceplate,
make sure that the enclosure seal is not
crimped or twisted. Do not over-tighten
corner screws (hand tighten only).
Faceplate can be rotated 90°.
