Chapter 1: Getting Started
Reshipping
If an IronHorse motor needs to be reshipped from the initial shipping point, the following procedures
should be followed to protect the motor from damage.
1) If the original packaging is to be used for reshipment, inspect the packaging for previous shipping
damage and repackage if necessary. Take care to protect the motor body, fan cover and shaft.
2) It is a good idea to bolt the motor to a platform that fits securely in the bottom of the shipping crate
or box. This helps prevent the motor from shifting during transport and thus protects the bearings
from damage.
3) A shaft lock device should be installed on motors from 100 to 300 hp prior to shipment. The shaft
lock helps prevent bearing damage.
4) Motors should only be lifted by the the eyebolt(s) provided on the motor. When lifting motors with
more than one eyebolt, use every bolt provided.
Long Term Storage
The following preventative measures should be taken when storing IronHorse motors for a long period of
time.
1) Store motors in a controlled temperature, dry atmosphere free of excess dirt, dust and airborne
particles.
2) Rotate the motor shaft every sixty days to prevent hardening of the bearing grease.
3) Warehoused motors should have the bearing grease purged and replaced every six months. Use
only Mobil POLYREX® EM Polyurea grease. For MTCP2 motors, use SKF, LGHP2 grease. For MTF2 and
MTDP motors, use Multemp, SRL grease or equivalent.
Warranty
• IronHorse MTSS stainless steel motors carry a one year warranty from the date of invoice.
• All other IronHorse motors (except MTSS) carry a two year warranty from the date of invoice.
For motors 40hp and smaller, valid warranty claims will be resolved by product replacement. Motors
50hp and larger must be evaluated by an authorized Electrical Apparatus Service Association (EASA)
service center. Valid warranty claims will be resolved by repair or replacement at the discretion of
AutomationDirect. See AutomationDirect Terms and Conditions in our current catalog or online at http://
www.automationdirect.com/static/specs/adpolicy.pdf for complete details.
Authorized EASA service centers are available nationwide. Visit the EASA website at www.easa.com to find
the nearest authorized service center. These shops may also be able to assist with non-warranty service.

Safety Information
Danger!
Hazardous Voltage! Before making any connection to the motor, disconnect all power to the motor.
Warning: Any electrical or mechanical modification to this equipment without prior written consent of
AutomationDirect.com, Inc. will void all warranties, may result in a safety hazard, and may void the cCSAus or cURus
listing.
Warning: To avoid physical injury, keep your hands and clothing away from all moving parts.
Wiring Notes: PLEASE READ PRIOR TO INSTALLATION.
1) During installation, follow all local electrical, construction, and safety codes for the country in which
the motor is to be installed.
2) Make sure the appropriate protective devices (circuit breaker or fuses) are connected between the
power source and motor controller.
3) Make sure that the leads are connected correctly and the motor is properly grounded. (Ground
resistance should not exceed 0.1Ω.)
4) Use ground leads that comply with AWG/MCM standards and keep them as short as possible.
5) Make sure that the power source is capable of supplying the correct voltage and required current to
the motor.
6) Do not attach or remove wiring when power is applied to the motor.
Applicable Codes
Most IronHorse® motors are cCSAus listed, and therefore comply with the requirements of the National
Electrical Code (NEC) and the Canadian Electrical Code (CEC).
IronHorse MTDP, open drip proof and MTF2, farm duty motors are cURus recognized and comply with the
requirements of the National Electrical Code (NEC) and the Canadian Electrical Code (CEC).
Because IronHorse, MTDP and MTF2 motors are UL recognized, it is the responsibility of the user to insure
that the installation complies with the conditions of acceptability as specified in the UR file.
Installation intended to meet the cCSAus requirements must follow the instructions provided in the “Wiring
Notes” as a minimum standard. Follow all local codes that exceed cCSAus requirements. Refer to the
technical data on the motor nameplate for electrical and performance data.
