The enclosure has cable entries for passing the instrument cables to the terminal board. These
entries have seals for specific cable sizes which will minimize the possibility of water or other
contaminants entering the box and causing problems. Plastic dowels are provided for unused
cable entries to prevent moisture and contaminants from entering the enclosure.
Actual gage connections to the terminal board will vary depending on the instrument type and
cable used. Note the following tables to get the general idea.
