■ Vertical Suspension of the Drive
Follow the procedure described below when suspending the drive with eye bolts or hanging brackets.
Models 20028 to 20130 and 40011 to 40124
WARNING! Crush Hazard. Use an adequate length of wire to ensure a 50° or wider suspension angle as illustrated in Figure 2.6 The
maximum allowable load of the eye bolts cannot be guaranteed when the drive is suspended with the wires at angles less than 50°.
Failure to comply may result in serious injury or death from falling equipment.
1. Pass wire through the holes of the two eye bolts or two hanging brackets.

WARNING! Crush Hazard. Use an adequate length of wire to ensure a 50° or wider suspension angle as illustrated in Figure 2.8. The
maximum allowable load of the eye bolts cannot be guaranteed when the drive is suspended with the wires at angles less than 50°.
Failure to comply may result in serious injury or death from falling equipment.
1. Remove the two hanging brackets from the drive lower side panels and bolt them on the top panel.
Note: 1. Tighten the hanging brackets with the specified tightening torque: M10: 18 to 23 Nm, M12: 32 to 40 Nm.
2. Four hanging brackets are attached to the top of IP20/NEMA 1, UL Type 1 drives 20154F, 20192F, 40156F, and 40180F.
