5.4.2 Fusing the DC-bus supply
When ECSxE power supply modules with a mains-side protection are used, the DC-bus
cables do not need to be fused.
When using capacitor modules in the DC-bus connection with basic devices of the 82xx
and 93xx series, use the following fuses:

Warnings!
ƒ Use UL-approved cables, fuses and fuse holders only.
ƒ UL fuse:
– Voltage 500 ... 600 V
– Tripping characteristic ”H”, ”K5” or ”CC”
5.4.3 Specification of the cables used
The cables used must comply with the required approvals at the place of installation
(e. g. UL).
Installation of the cables to EN 60204-1 (1998)
Shielded cables
Observe the following to increase the effect of shielded cables:
ƒ A good shield connection:
– Ensure a contact surface as large as possible
ƒ Low shield resistance:
– Only use shields with tin-plated or nickel-plated copper braids (shields with steel
braids cannot be used).
ƒ High contact ratio of the shield braid:
– At least 70 ... 80 % with 90 ° overlap angle
