Model 2A Operation And Service Manual
2A Manual A5 21 January 2005 Page 4
WARNING
Any interruption of the protective grounding conductor (inside or
outside the instrument) or disconnecting of the protective earth
terminal will cause a potential shock hazard that could result in
personal injury. Grounding one conductor of a two conductor out-
let is not sufficient protection.
Whenever it is likely that the protection has been impaired, the instrument must be
made inoperative and be secured against any unintended operation.
If the instrument is to be energised via an autotransformer (for voltage reduction)
make sure the common terminal is connected to the earthed pole terminal (neutral)
of the power source.
Instructions for adjustments while the covers are removed and for servicing are for
use by service-trained personnel only. To avoid dangerous electrical shock, do not
perform such adjustments or servicing unless qualified to do so.
For continued protections against fire, replace the line fuse(s) with fuses of the
same current rating and type (for example, normal blow time delay). Do not use
repaired fuses of short-circuited fuse holders.
