Supply
The power wires must have a minimum rating of 1.1 x
FULL LOAD CURRENT. For UL requirements, the
wires must be rated for 1.25 x FULL LOAD CURRENT.
Control wiring must be 18 gauge or larger.
Supply Connections
The 590 DRV Digital drive has ground terminals for
each incoming and outgoing supply. A substantial
connection must be made to the incoming supply ground
terminal near terminals L1, L2, and L3 (Figure 3.2). The
ground terminals at the bottom of the drive can be used
for armature ground and grounding the auxiliary 120
VAC loads.
