2-4 ELECTRICAL CONNECTIONS
NOTE
The enclosure is a NEMA 4. All entry loca-
tions must be sealed.
Connect all required signal cables to the con-
nections at the bottom of the MicroCEM. The
cable locations are indicated on the inside
bottom cover of the MicroCEM box. The ac-
tual electrical connections will be specified in
the Application Data package. All connections
are not necessary for every application.
Cable length for these signals should not ex-
ceed 3,000 feet (914 meters), to avoid exces-
sive capacitance and corresponding signal
distortion.
All electrical connections are made through
the bottom of the MicroCEM enclosure using
circular connectors.
