4.9 Mains / Utility Input
For reasons of personal health and safety, the ITW GSE 7400 unit must always be protected
by grounding the PE terminal ( ) during charging.
NOTE: The minimum ground wire size as below table:

Consult local authorities to ensure this meets local requirements.
(Specifically in accordance with Canadian Electrical Code, Part 1 where applicable)
Note
We strongly recommend using a CEE-type outlet with interlocking switch to prevent disconnection
while in use/charging.
The mains/utility input connection to the unit should be externally pre-fused according to the table
below:

*Limited by ITW GSE 7400 to maximum 100A.
Note
Maximum grid power in amperes (in steps of 1A to 100A) can be set according to the available
mains/utility outlet, maximum setting is limited to 100 A.
ITW GSE recommends setting the maximum current 5A lower than grid power available.
Please refer to section 6.2 & 6.5 for further information.
4.10 400 Hz Output
On delivery, the 400 Hz neutral is connected to the protective earth (PE) terminal. If a floating output is
required, the green/yellow jumper wire must be removed.
Regardless of installation method, local regulations and legislation must be followed to ensure
personal health and safety.
