4.2 Unpacking and Damage Inspection
Caution : Take care when handling system. All movement, lifting and installation of
the 5203 Electromagnet must be under the supervision of an experienced person to
prevent the possibility of serious injury or damage to the electromagnet and associated
equipment.
To unpack the electromagnet please use the following procedure.
1.
First remove the wire clips and screws from the ‘top crate cover’ of the shipping crate.
2.
Remove the top crate cover and set it aside. Remove the protective foam packaging material.
3. Inspect the magnet and junction box to ensure that no damage has occurred during shipment.
If damage is evident report the damage in detail to the shipper for claim and simultaneously
notify GMW in case assessment of the damage must be made. If no damage is found proceed
with magnet unpacking and installation.
4.
Carefully lift magnet, cables, hoses and junction box clear of the shipping crate.
5.
All conductors of the same ac circuit routed to the same location shall be contained in the same
raceway. Conductors external to the electrical equipment enclosure(s) shall be enclosed in
raceways (ducts).
4.3 Magnet Power Supply
For full power operation, the 5203 Projected Vertical Field Electromagnet should have a power
supply with an output current rating of up to 63A for a DC field and 100A for a triangle wave
current. To provide a stable magnetic field the power supply should be operable in “current mode”
to deliver a constant set current with overall stability of approximately 1% of full-scale current.
It is essential that the power supply to have an interlock input that will inhibit its
output when the interlock circuit is in an OPEN state. This is referred to as a
'NORMALLY CLOSED' interlock. A normally closed interlock will ensure that the
DC power supply will remain in an inhibited state should the interlock cable become
disconnected.
4.5 AC Mains Connections
Never connect or remove the AC Mains cables from the power supply without first
Locking-out and Tagging-out the AC Mains power source. In some cases, this power
source may be a locking NEMA plug, and in systems with higher current draw, it
should be direct wired into an appropriately fused, three phase disconnect box.
AC Mains connections should be made by a licensed electrician. Many facilities have
such personnel on site.
Please refer to the Power Supply Operators Manual for complete details on AC Mains
power connections.
