Harmony Ball Return Manual – 400-254-022 3 Rev. Date 3/16
4.0 SAFETY
It is important to lockout-tagout (LOTO) a ball return prior to installation or maintenance of the
lift. This safety procedure ensures that the ball return is powered off until the completion of
installation or maintenance. Hazardous power sources must be isolated and made inoperative.
This varies slightly depending on the country of installation:
4.1 U.S.A.
For installations in the U.S.A., each Harmony ball lift will need to be installed with a local AC
power disconnect (>10A, non-fused). The disconnect should be installed under the approach
below the ball rack access cover area. In order to LOTO lifts installed this way, the pullout
handle will need to be removed from the disconnect and then the disconnect must be locked
closed with the pullout handle removed. For other types, the disconnect switch must be placed
in the OFF position and then locked.
4.2 E.U.
For European installations, a Schuko power outlet should be installed within 3m (10ft) of the
ball lift. To LOTO this machine, a LOTO box must be placed around the ball lift’s electrical plug
and locked so that the plug cannot be placed in the socket. This ensures that no electricity can
reach the machine during installation or maintenance.
Disconnect’s pullout
handle must be removed
(or switch must be
moved to the OFF
position).
Disconnect’s hood/lid
must be locked.
The LOTO box must be closed and locked
around the plug.
