The maximum
input current on
each way is 100 A.
Output terminal 1–4: The maximum
output current on one way is 60 A.
Output terminal 5–10: The maximum
output current on one way is 60 A
(Breakers of other rated currents can
also be configured as needed).
The maximum input
current on each
way is 100 A.
6.2 Cabling Requirements
Routing Principles
l
Power cables and grounding cables should be routed in a smooth and straight manner,
see

l
If a cable is not long enough, use a longer cable. Do not connect or solder two or
more short cables to make a long one.
