External Power Cable -
For external power supply control module there is additional AC power cable:
AC Power Cable (Australia
Standard)
Grounding:
The PowerCube-H1 modules' grounding is based on metal directly touch
between the module's surface and rack's surface. So it needn't grounding
cables at all. If uses normal rack, it can remove the paint at the
corresponding place. Or install a grounding cable to the grounding point of
the modules.
CAUTION
The rack/cabinet grounding goes through the connection with Metal base support or grounding
cable through the stud screw at the bottom of the rack/cabinet. The connection is necessary.
