Requirements on the installation
Safety-Relevant Conditions
• You have to make sure that there is no transient coupling to the safety-related control
voltage V
24 V safe
.
• Observe the values specified for safety components when designing the safety
circuits.
• Use only voltage sources with safe disconnection (SELV/PELV) according to
EN 60204-1 for any DC 24 V voltage supply (safety-related control voltage V
24 V safe
and functional control voltage V
24 V in
) of the safety-related BST brake module.
In case of a single fault, the voltage between the outputs or between any output and
grounded parts must not exceed DC 60 V.
• Do not interconnect brake cables of several brake control systems.
• For disconnection of group drives, observe the switching capacity of the safety
switching device and the maximum permitted voltage drop on the safety-related
control voltage V
24 V safe
.
• Adhere to the technical data of the BST module and the brake.
• Adhere to the general installation regulations in the "Installation" chapter.
