Harsh Enclosure Cable Glands - Mettler Toledo IND560 PDX Guia De Instalacion

Harsh Enclosure Cable Glands

The IND560 PDX harsh environment 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:
•
Pass the cables through an appropriately sized cable grip before connecting
the wires. Figure 2-14 shows one load cell cable installed in its cable grip,
and a second grip disassembled.
•
Depending upon the diameter of the cable to be installed, select one of the two
different sized 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.
