3.3 Electrical connection and operation
The spring-applied brake
must be connected to an
AC power source via
jumpers 1 (BA1) and 2
(BA2) on the connecting
terminal (19) (see Fig.
9/2). The customer-
specific connecting cable
must be connected to the
terminal (19) by means of
a special cable entry
sleeve (30). Remove the cover (26) of the connector box
(25) so that the individual strands of the connecting cable
can be connected to the terminal. The threaded cable
entry sleeve (30.1) of the sleeve assembly (30) is factory-
fitted to the solenoid housing (1.1) (see Fig. 9/1). Tighten
the threaded entry sleeve (30.1) to secure the customer-
specific connecting cable. The sealing ring (30.2) seals the cable entry. Tighten the machine screws (30.3) to
strain-relieve the connecting cable (cable diameter 17…19 mm). The clamping strap (30.4) locks the
threaded cable entry sleeve (30.1) in its position so that it cannot rotate. After completion of these steps, the
cover (26) of the connector box (25) must be reinstalled.
Attention!
When fixing the cover (26) to the connector box (25), the M
A
tightening torques of the machine screws
specified in Table 13/1 must be strictly observed. The flat seal (9) and spring washer (28) must be installed
as shown in Fig. 6/1.
The supply voltage is rectified by the built-in bridge rectifier. Depending on the brake size and torque, voltage
ripple due to intermittent power supply may cause brake humming or incorrect brake operation. Perfect
brake operation must be ensured by the user or system manufacturer by providing suitable electrical
controls.
