Other electrical considerations
Additional electrical considerations include:
•Electromagnetic interference (EMI), such as is generated by NMRs, radio
transmitters, and microwave links, may interfere with system performance.
•Protect the system from static electricity by observing humidity and
temperature requirements. Minimize the presence of nonconductive
products such as carpets and vinyl floor tiles.
•Install emergency-off pushbuttons that can disconnect power to the
ventilation system and all electric equipment in the room except overhead
lighting.
•Provide separate convenience outlets for building maintenance and other
appliances. Convenience outlets must be on circuits separate from the MSD
system. Convenience outlets must share the nor mal building distribution
ground, not the MSD system ground.
•In some geographical areas it may be advisable to install lightning
protection for personnel and equipment.
WARNING Do not use extension cords with the MSD or GC. Extension cords normally are not

rated to carry enough power and can be a safety hazard.

NOTE Maintain easy access to the power cords so th ey can be disconnected for maintenance.
