Installing the Power Supply Cables
The MS27102A features an IP67 rated power connector. However, for the connection to be weatherproof, the weatherproofing gland must be installed around the connector and cable. The following illustration shows how to install the power connector’s weatherproof gland.
Power Supply Gland Assembly
1. Thread power conductors through the gland’s components and secure the seal.
2. Connect the conductors to the connector and tighten the Allen screw to secure.
3. Install the connector to the instrument with the O-ring as shown.
The following illustration shows the polarity of the power connector as viewed from the front of the instrument casing.
Power Supply Pin-out
1. Positive DC lead (11 V to 24 V)
2. Negative DC lead (ground)
3. Note: the third pin has no internal connection.
Caution 
The MS27102A chassis provides two earth ground connections. Be sure to ground the instrument chassis and any antenna installations in accordance with your local regulatory requirements. Failure to properly ground the equipment may present an electric shock hazard and contribute to static noise interference.
