Ensuring the degree of protection
7.5.1
Degree of protection IP66/67, Type 4X enclosure
The measuring device fulfills all the requirements for the degree of protection IP66/67,
Type 4X enclosure.
To guarantee the degree of protection IP66/67, Type 4X enclosure, carry out the following
steps after electrical connection:
1. Check that the housing seals are clean and fitted correctly. Dry, clean or replace the
seals if necessary.
2. Tighten all housing screws and screw covers.
3. Firmly tighten the cable glands.
4. To ensure that moisture does not enter the cable entry, route the cable so that it
loops down before the cable entry ("water trap").
5. The cable glands supplied do not ensure housing protection when not in use. They
must therefore be replaced by dummy plus corresponding to the housing protection.
NOTICE
Standard dummy plugs used for transportation do not have the appropriate degree of
protection and can result in damage to the device!
‣
Use suitable dummy plugs corresponding to the degree of protection.
