◆
Using the Mounting Rails to Move the Bypass
Use the holes in the mounting rails attached to the bypass to temporarily lift the bypass when you install it. Do not let
the bypass stay vertically or horizontally suspended or move the bypass over a long distance while it is suspended.
Before you install the bypass, make sure that you read these precautions:
WARNING!
Crush Hazard. Before you hang the bypass vertically, use screws to correctly attach the front cover and other
components. If you do not secure the front cover, it can fall and cause minor injury.
WARNING!
Crush Hazard. When you use a crane or hoist to lift the bypass during installation or removal, prevent more than 1.96
m/s
2
(0.2 G) vibration or impact. Too much vibration or impact can cause serious injury or death from falling equipment.
WARNING!
Crush Hazard. When you lift the bypass during installation or removal, do not try to turn it over and do not ignore a
hanging bypass. If you move a hanging bypass too much or if you ignore it, it can fall and cause serious injury or death.

Vertical Suspension
To use the hanging brackets to vertically suspend the drive, lift the drive with this procedure:
1.
Put wire through the two holes in the hanging brackets.
A - Suspension angle of at least 50 degrees
B - Hanging bracket (2)
Figure 2.5 Vertical Suspension
2.
Use a crane to gradually wind up the wire. Visually make sure that there is sufficient tension in the wire, then
lift the drive to its correct location.
3.
Prepare the control panel for installation, then lower the drive.
Note:
When you lower the drive, stop before the drive touches the floor, then slowly lower it the remaining distance.
■
Horizontal Suspension
When horizontal suspension is necessary, use this procedure to hang the bypass:
1.
Put the bypass on the ground horizontally.
NOTICE:
When you attach a horizontal lifting cable or chain to the bypass, use a jig or pad between the wire and the
bypass. The wire can scratch the drive and cause damage to the bypass.
