• For the connection compartment (Ex d version); power supply cable, circuit cable:
Choice of cable gland M20 × 1.5 or thread for cable entries ½" NPT or G ½".
Ensure that the Ex d cable glands/entries are secured against self-locking and the associated seals are
arranged directly on the housing.
• For connection compartment (Ex e version);
power supply cable, circuit cable: Choice of cable gland M20 × 1.5 or thread for cable
entries ½" NPT or G ½". The cables must be installed such that they are fixed in place. Adequate strain relief
must be ensured.

Warning!
When using cable glands M20 × 1.5:
• Only approved cable glands may be used (see Page 16 "Installation instructions").
• The cable glands must be very leak-tight.
You can find information about the cable specification in the associated Operating Instructions.
