IronHorse GSD4A / GSD4 DC Drives User Manual – 2nd Ed. Rev. A – 10/14/2019
Installation, Wiring, External Fusing (GSD4A/GSD4 Models)
Install open-frame drives in an enclosure with a volume at least three times
the volume of the open-frame drive.
Do not mount DC drive where ambient temperature is outside the range of -10
to 45 °C (14 to 113 °F).
Size all wires that carry armature or line currents as specified by
applicable national, state, and/or local codes. All other wires may be 18AWG
or smaller as permitted by the codes.
Separate control wires from the armature and AC lines when routed in conduit
or wire trays.
These drives do not provide motor over-temperature sensing or motor overload
protection. The need for additional motor overload and motor over-
temperature protection shall be determined based on conditions in the end
installation in accordance with the NEC.
