D.9.2 Devie protetion
Place in semiconductor fuses with the triggering characteristic gR DIN VDE 0636-201 / IEC 60269-2-1 HD
630.2.1 54. Switch these in series to the cable protection fuses. These protect the input-sided rectifier-
triggering, in case of a short circuit, a gainst completely destruction , so that a repair of the device is possible.
Execute the protection according to EN 60204-1 (Electrical equipment of machines). Dimension the suitable
fuses d ependent on the rated current and the linit load integral value.

D.9.3 Cable protetion and devie protetion
You have two possibilities to protect the cable and the device:
• Connect cable fuse protections and semiconductor fuses in series
• Use total range fuses
At selection of the total range fuses consider the current carrying capacity of the supply cables, which are
connected to the device and the permissible and the limit load integral value.
The following total range fuses are recommended for devices of series BM340X resp. BM341X:
• Bussmann 16A/690V: 170M1559
• SIBA 16A/690V: 2047734/16A
1)
• Siemens 16A/690V: 3NE1 813-0

In the course of certification according to UL 508 C the above mentioned types of SIBA and Siemens were
used and checked.
D.9.4 24V-extra-low voltage protetion
If you consider UL 508 C, assure by the use of fuses that X201-1,2,5,6 is at the maximum loaded with 4A (valid
for b maXX® BM340X and b ma XX® BM341X) resp. 5A (valid for b maXX® BM342X) and X26 with maximum
1A.
