IND246 Terminal Installation Manual

Cable Glands

The IND246 terminal is designed to withstand severe washdown environments.
However, care must be taken when installing cables and/or connectors that enter
the terminal enclosure. To ensure a watertight seal:
•
Before connecting wires, pass the cables through an appropriately sized cable
gland. Figure 2-11 shows a cable gland with its clamping nut removed.
•
Depending upon the diameter of the cable to be installed, select one of the
rubber grommets (if required) to properly seal around the cable.
When making cable terminations inside the harsh enclosure, ensure that the
cable length from the terminal strip/connector to the terminal housing is
sufficient so that no strain is placed on the connector assembly when the
housing is in the fully open position.
After making the wiring connections as described in the next section, ensure
the nut on the cable gland is tightened properly to seal around the cable.
Ensure that this seal is watertight.
Cable shielding should be grounded to the inside of the IND2460's enclosure
as close as possible to the entry point. Ground studs are provided on the
interior of the enclosure for this purpose.
