CAUTION!
Reversing polarity of the Bus Power (+) and
Power Common (-) will cause a short circuit, which must be
protected by the input fuse. See fusing below. If a fuse is not
installed the drive could be permanently damaged.

Twelve-gauge wire is recommended for bus power to reduce
voltage drop across the wire during peak power demands. If the
application does not require high peak or continuous power, the
wire gauge can be reduced, with a corresponding reduction in
fuse rating.
WARNING!
If the wire gauge for bus power is reduced
the fuse Amp rating must also be reduced in accordance with
wire size, type and local regulations.
5.8 GROUNDING
WARNING!
The actuator and all power supply PEs and
negative connections must be properly grounded using a single
point grounding method.
