NOTE 1: Loop power supply electrically isolated
from customer equipment
NOTE 2: Actual value of loop current (mA) is
disregarded
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). Face-
plate can be rotated 90°.
