Safety-Relevant Conditions
Only SEW disk brakes may be connected to the BST module.
4.2
Requirements on the installation
The line between the safety switching device/safety controller and the safety-related
BST brake module, terminal 5/6 (V
24 V safe
) is referred to as safety-related control line
(for safe disconnection).
Observe the following requirements on the installation:
• Power lines and safety-related control lines have to be installed in separate cables.
• The total cable length between the safety switching device/safety controller and the
safety-related BST brake module is limited to a maximum length of 100 m for EMC
reasons.
• The total cable length between the safety-related BST brake module and the
connected brake must not exceed 200 m.
• Wiring must comply with EN 60204-1.
• The installation space (control cabinet) must have at least degree of protection IP54.
• The safety-related control lines must be routed according to EMC guidelines and as
follows:
– Outside an electrical installation space: Shielded cables must be routed perma-
nently (fixed) and protected against external damage, or other equivalent
measures.
– Individual conductors can be routed inside an electrical installation space.
Observe the respective regulations governing the application.
– It is essential that you apply the shielding at both ends on the housing.
• The safety-related control voltage V
24 V safe
may not be used for feedback.
