Dangers in handling the NBS emergency brake
The internal electronic circuit of the NBS emergency brake is connected to
mains voltage. Before intervention in the control system, required for
example with the safety catch activated or during a brake test, the power
supply to the drive is to be disconnected before starting work and the
installation is to be secured against inadvertent activation.

the user or third parties, or impairment of the assembly or other assets can
arise.
Malfunctions that can impair safety must be rectified immediately.
Make sure that the brake release screws (screw head marked in red) have
been removed from the NBS emergency brake before beginning operation of
the elevator, as otherwise the brake will not function in an emergency.
