IronHorse GSD3 DC Drives User Manual – 1st Ed, Rev C – 10/15/2019
Installation and Wiring
Install open-frame drives in an enclosure with a volume at least three
times the volume of the open-frame drive.
Do not mount GSD3-24x-2Cx DC drive where ambient temperature is outside
the range of -10 to 45 °C (14 to 113 °F).
Do not mount GSD3-24x-3N4 DC drive where ambient temperature is outside
the range of -10 to 40 °C (14 to 104 °F).

* For wiring connections, use customer-supplied Sta-Kon 0.25 in x 0.25 in spade connectors or similar.
** +F connection is only for Shunt Wound motor; NOT for Permanent Magnet motor.
For motors with dual voltage field, i.e. 50/100V or 100/200V, connect the highest value.
*** Use normal-blow fuses in series with all ungrounded (hot) AC inputs, rated to 125% of motor current.
NOTE: Fuse both AC input lines for 240 VAC input, where both lines are hot. For line-to-neutral
circuits, fuse the hot input line and connect it to AC1.
**** GSD3-240-3N4 drives include a replaceable built-in fuse wired in line with AC1.
(Fuse is 250VAC, 6.3A Littlefuse 21606.30 or equivalent.)
