2-4 ELECTRICAL CONNECTIONS

NOTE

The enclosure is a NEMA 4. All entry locations must be sealed.

Connect all required signal cables to the connections 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 exceed 3,000 feet (914 meters), to avoid excessive capacitance and corresponding signal distortion.

All electrical connections are made through the bottom of the MicroCEM enclosure using circular connectors.
