2.5 EMI
The 94011A(-ES) housing contains EMI (Electro Magnetic Interference) under normal operating
conditions. However, ignition of an arc lamp requires high voltage pulses to break the lamp down and
a high current dump (10’s of Amps discharge) to sustain the arc. Arc lamp ignition creates significant
electromagnetic energy. The high level of EMI integrity of the source contains most of this transient
energy, but additional earthing, careful cable routing, and EMI shielding may be necessary to protect
sensitive digital circuitry from these events.
Recommendations
1. Start the arc lamp before powering nearby computer systems.
2. Keep the computer at least 2 feet away from the ignitor/power supply.
3. Use a different outlet and line for the computer and ignitor/power supply.
2.6 HEAT
The lamps become very hot during operation, and may remain so for many minutes after being shut
off.
Recommendations
1. The fan will remain On for 2 minutes after lamp turn off, after which the power cord can be
removed. Wait at least 10 minutes after turning off the lamp before removing the housing top
cover to access the lamp.
2. Approach the lamp as if it were hot under any circumstances.
3. Allow at least 2 inches of clearance near the fan opening and ventilation slots for adequate
cooling of the lamp and power supply.
