3. WARNINGS
PERSONNEL SAFETY
The Model 5203 has a low level of fringe field. In operation the magnet
fringing field can be in excess of 0.5mT (5G). This can cause malfunctioning
of heart pacemakers and other medical implants. We recommend that the
fringing field should be mapped and warning signs be placed outside the
0.5mT (5G) contour. Entry to this region of higher field should be restricted
to qualified personnel.
FERROMAGNETIC OBJECTS
During operation the magnet exerts strong magnetic attraction towards
ferromagnetic objects in the near vicinity. Loose objects can be accelerated
to sufficient velocity to cause severe personnel injury or damage to the coils.
Keep ferromagnetic tools clear.
ARCING
This magnet stores considerable energy in its field during operation. Do not
disconnect any current lead while under load or the magnetic field energy
will be discharged across the interruption causing hazardous arcing.
HIGH VOLTAGES and CURRENTS
Be aware that the AC mains input to the DC power supply and the output
to the electromagnet are high voltage. Follow lock-out / tag-out procedures
during all maintenance procedures. Verify that all electrical connections
are secure and properly strain relieved. Loose connections may overheat
and cause damage to equipment.
HOT COIL RESISTANCE
Do not exceed the maximum coil hot resistance given in the specifications or
coil overheating and possible damage may occur.
