Warnings:
This Dings magnet emits a powerful magnetic field when energized. The magnet must be
positioned within an inaccessible or guarded area so that no contact can be made with the
magnet while it is in operation.
The surface of the magnet box may reach temperatures of up to 230ºF (110ºC) while
operating. Take care not to touch magnet surface and allow sufficient cooling time before
handling.
Before performing maintenance, the magnet must be de-energized and allowed to cool for at
least 6 hours. Lock out/tag out electrical supplies to prevent unexpected movement or
magnetization during maintenance.
The magnet box is filled with transformer oil to cool the magnet during operation. Inspect oil
level and quality regularly to prevent damage to magnet components.
CAUTION: STRONG MAGNET
Strong magnetic field may have an affect on pacemakers and other electrical devices. Please
contact the device manufacturer for further information.

Unpacking and Handling
Upon receiving, check all packaged material for shortage of parts and possible damage.
Report shortages and damage to the carrier who delivered shipment. The magnet was
shipped fully assembled, ready for operation. Electrical connection is required to a suitable
source of direct current such as a rectifier.
Magnet
This Dings electromagnet was shipped using a pallet or 4” x 6” wooden beams as supports
under the two sides of the magnet. After unloading, the magnet should never be placed
directly on the ground. Rather, wood beams or some other means of support should be placed
beneath the two sides of the magnet box to raise the magnet and belt above the ground.
The magnet should always be moved using the sling assembly provided. Never use a forklift
or other device to lift the magnet from the bottom.
The magnet should be stored indoors prior to installation.
Rectifier
The rectifier is a sensitive piece of electrical equipment. It has been shipped on a separate
pallet to protect it during shipment. Take care not to drop or shake this equipment during
handling.
The rectifier may be left strapped to the pallet while being moved. If it has been removed from
the pallet, make sure it is securely fastened to forklifts or winches for moving.
The rectifier should be stored indoors prior to installation.

Recommended Storage of Overhead Magnets
1) It is essential to keep moisture out of magnet cooling oil.
2) The following precautionary procedures are recommended:
a) Store magnet indoors in a low humidity, even temperature environment if possible.
b) Keep water and any other form of moisture away from the magnet while in storage.
3) This is a procedure for indoor storage only. Outdoor storage is definitely not advised and
will null and void our warranty on the magnet assembly.
4) Rectifiers:
a) It is mandatory that the rectifier be stored indoors away from water and moisture.
b) It is recommended that the rectifier be put in a plastic, tightly sealed cover or bag to
prevent moisture from getting into the rectifier if it’s stored in an unheated building.
c) If possible, rectifier should be stored in an even temperature environment.
