GPDM Connection Instructions
WARNING
Sheet metal and exhaust air at the top of the enclosure are hot. Avoid contact.
WARNING
V BUS+ and V BUS- terminals are at hazardous voltages when power is applied,
and for up to 30 seconds after power is removed. Lower voltages may still be
present for several minutes after power is removed. Reinstall the clear plastic
terminal cover after you make connections.
WARNING
Only connect V BUS
±
terminals of drives that share the same fused AC power
source, as shown in the next drawing.
Connecting the GPDM
1.
Connect up to three GV, GV6 or GV6K Servo Drives to one GPDM. (Connect
only
GV(6)(K)-U3n/U6n/U12n drives; do not connect any other drives to the GPDM.)
2.
Connect drive V BUS+ terminals to V BUS+ on the GPDM.
3.
Connect drive V BUS– terminals to V BUS– on the GPDM.
4.
For multiple drives, connect drive safety earth terminals to a single point ground.
5.
Keep connections between drive and GPDM less than 12 inches (300 mm). Use 14
AWG (2.5 mm
2
) or greater diameter wire.
