Gem6K Hardware Installation Guide
Step 3 – Connecting AC Power
Power Requirements
Acceptable ranges of AC input voltage are listed below for each drive :
Drive
AC Input Range
GT6K-L5/L8
95 – 132VAC
GV6K-L3n
95 – 132VAC
GV6K-U3n/U6n/U12n
95 – 264VAC
GV6K-H20n
165 – 264VAC [single phase (1
∅
) or three phase power (3
∅
)]
GV6K-H40n
165 – 264VAC [three phase power (3
∅
) only]
WARNING
You must connect the drive’s protective conductor terminal, marked with the
symbol, to a reliable system safety earth. Make the connection directly, by means
of a low impedance path less than or equal to 0.1 ohm (no fuses, etc.). Under
normal operation, no current should flow through the safety earth connection.
WARNING
The drive’s barrier strip terminals are at hazardous voltages when power is applied
to the drive, and 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.
Fuse Information
Gem6K drives have no internal fuses. For safety, you must provide a fuse in each
of the AC input lines. Recommended fuse types and sizes are:
