6.4.2
Selecting cables
Take the following criteria into account when selecting the connecting cables for the auxiliary
circuits:
● Rated current
● Rated voltage
● System-dependent conditions, such as ambient temperature, routing type, cable cross-
section as defined by required length of cable, etc.
● Requirements according to IEC/EN 60204‑1
● Requirements according to IEC/EN 60079‑14
6.4.3
Bringing cables into the auxiliary terminal box and routing them
The type designations of the mounted auxiliary terminal boxes, their arrangement, and the
relevant connection terminals are documented in the "Technical data and drawings" section.
The information required to connect the auxiliary circuits is provided in the terminal diagram
located on the inside of the terminal box cover and in the "Technical specifications" section.
The connectable cable cross-sections and the dimensions are listed in "Technical Data".
Adapting the cable glands
A plate is bolted to the terminal box enclosure via a rectangular cutout through which the
connecting cables enter. Normally, this plate is supplied without threaded holes for the cable
glands. This enables you to adapt the number and size of the cable glands to the rated
conditions.
Degree of protection
Use only cable glands that are suitable for the degree of protection of the auxiliary terminal
box.
Introducing and routing the cables
1. Open the auxiliary terminal box and undo the cable entry plate screws.
2. Drill the required number of holes or threads in the required size of the cable gland into the
cable entry plate.
3. Mark the cables if necessary for subsequent assignment.
4. Pull the cables through the cable glands and the entry plate, and connect the cables.
5. Fit the cable entry plate.
6. Make sure that the seal on the screwed sockets for the cable glands satisfies the degree
of protection.
