Suitable cables for spring-loaded terminals
The following cables are suitable for connecting to the spring-loaded terminals
Cross section
0.08 ... 1.5 mm²
AWG 28 ... 16
0.08 ... 1 mm²
AWG 28 ... 18
CAUTION
Short-circuit
Use end sleeves for small conductor cross-sections.
Otherwise the stripped litz wire may buckle when it is inserted into the terminal. In this case,
the line is clamped onto the insulation, which will cause contact problems.
Load cell cables
DMS load cells are supplied with connecting cables.
Connecting a PAL cable
For non-intrinsically safe use of the junction box, a PAL cable must be connected. An M6x12
bolt is provided for this on the mounting flange. The PAL cable must be protected against
becoming loose on its own, which is achieved by a cable eye crimped to the cable.
Danger of explosion
Please observe that in the case of shielded cables of intrinsically safe circuits in hazardous
areas, only one grounding is permissible.
If grounding is to be on both sides, an equipotential bonding conductor with at least 4 mm²
must be connected.
