General requirements

Fusing

6.3.3 Fusing
Fuses in UL−conform systems have to be UL−approved.
ƒ
The rated voltages of the fuses have to be dimensioned according to the
ƒ
DC−bus voltage.
The use of DC−bus fuses is a recommendation.
ƒ
–
If DC−bus fuses are used, they have to comply with the specifications in
chapter 4.2.3.
It is the user's responsibility to take further standards (e. g.: VDE 0113,
ƒ
VDE 0289, etc.) into consideration.
Connection
Connect cables for the power supply module (934X), controller (93XX) and
ƒ
further braking units (935X) in the DC−bus connection to the screw
terminals +UG, −UG on the top at the braking unit and the controller.
Observe the screw−tightening torques:

PE
For shielded cables:
Apply the shield correctly (required parts in the accessory kit):
ƒ
–
Screw shield sheet onto the fixing bracket.
–
Clamp the shield with clips. Do not use as strain relief!
–
The PE connection is effected via the fixing bracket.
6.3.4

Temperature monitoring

(
Stop!
ƒ
Loop the temperature switches of the external brake resistors or the 9351 brake
module in the monitoring circuit, so that the following reactions are triggered
if the temperature monitoring responds:
All controllers which are connected to the braking units are disconnected
ƒ
from the mains.
Controller inhibit is set for those controllers.
ƒ
The internal temperature contact of the 9351 brake module (T1/T2 terminals)
can be loaded with a switching capacity of 0.5 A/230 V.

Always connect the temperature monitoring.
– The temperature monitoring is required for the safe
disconnection in the case of fault.
