DC Fuse Replacement (Frame 6 Regen Unit - 4Q)
The DC fuse(s) can be replaced in-situ. With the front of the drive removed (the Control Panel Assembly), the replacement should take about 20
minutes. Removing the Control Panel Assembly from the cubicle completely will make access easier, but requires the removal of all connections made
to it. It may be possible to support the Control Panel Assembly (
11.25kg/25 lbs) and sling it away from the Phase Assemblies far enough to gain
access.
Removal
1. Loosen the retaining screws in the Field Controller plug. Unplug all connections to the Door Assembly (control connections) and the Field
Controller (Auxiliary Plug and Field Plug).
2. Undo the fixings to remove the front cover from the Control Panel Assembly.
3. Disconnect the flying leads of the Control Panel Assembly from the three Phase Assemblies. Remove the external earth connection(s) made to the
Front Cover.
4. Remove the 12mm x M6 fixings in the four corners that secure the Control Panel Assembly. Loosen the top and bottom central support screws (but
do not remove) and lift the Control Panel Assembly away from the three Phase Assemblies.
