Planning details
6.8 Lighting system
The lighting facility is not an integral part of the supply and must be finished by the customer
before installation begins.
There are no system specific requirements for the operating and technical rooms. When select-
ing the lighting facility in these areas, the country specific specifications and requirements for
work place lighting must be met (occupational standards).
In the area of the magnet room, lighting facilities must not be below the minimum distances to
an MR system listed in the chapter
Measurements and room dimensions [

. When se-
lecting lighting methods, their compliance with magnetic stray fields must be noted. The use of
combinational circuit parts, transformers, and dimmers is not permitted in the immediate vicinity
of the magnet. The operating areas in front of and behind the magnet should be very well lit.
If an MR system is installed in an HF shielded room, the magnet room lighting and any AC sock-
ets for additional equipment must be connected to the central electrical power distributor at the
connection points provided for this purpose. All supply lines into the HF shielded room must
pass through appropriate filter plates.
6.9 Ventilation and air conditioning
6.9.1 Overview
The following areas and units must be fitted with a cooling system available for operating the
MR system on the building side:

(*) the real requirement depends on the configuration of the instrument
No additional ground loop should be established by the lighting system. When there is discon-
nected ground at the electrical power distributor, there must be infinitely large resistance be-
tween each ground contact of the lighting facility and all conducting points within the HF
shielded room.
