7.3.3 Fusing
ƒ Fuses in UL−conform systems have to be UL−approved.
ƒ The rated voltages of the fuses have to be dimensioned according to the
DC−bus voltage.
ƒ The use of DC−bus fuses is a recommendation.
– DC−bus fuses must comply with the specifications. (
¶ 75)
ƒ It is the user’s responsibility to take further standards (e. g.: VDE 0113,
VDE 0289, etc.) into consideration.
Connection
ƒ Connect cables for the power supply module (934X), controller (93XX) and
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.
ƒ Observe the screw−tightening torques:
Terminals Tightening torques
[NM] [lb−in]
+UG, −UG 0,5 ... 0,6 4,4 ... 5,3
PE 1,7 15
For shielded cables:
ƒ Apply the shield correctly (required parts in the accessory kit):
– 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.
7.3.4 Temperature monitoring
(
Stop!
ƒ Always connect the temperature monitoring.
– The temperature monitoring is required for the safe
disconnection in the case of fault.
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:
ƒ All controllers which are connected to the braking units are disconnected
from the mains.
ƒ Controller inhibit is set for those controllers.
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.
