{ Danger!
ƒ S1, S2 and S3 have a mains potential!
– Wait for at least 3 minutes before changing over the switches.
5.4.1 Braking units with brake resistor
You can connect the 935X braking units in parallel in any combination if an
individual braking unit cannot completely convert the arising braking power.
Important notes
ƒ Connect each braking unit in parallel to the terminals +U
G
and −U
G
of the
controllers.
– For total lengths £ 0.5 m a shielding is not required.
ƒ Connect a brake resistor to each 9352 brake chopper at the terminals RB1
and RB2.
ƒ Connect the contacts (NC contacts) of the brake resistor temperature
monitorings in series.
ƒ Make sure that the minimum resistance specified in the technical data of
the braking units is observed − also in the case of parallel connection of
brake resistors (see chapter 3.3).
ƒ Wire brake resistors connected in parallel so that a simultaneous
connection and disconnection is ensured. Otherwise the braking power is
not divided equally to the brake resistors connected.
