Caution
When the instrument is connected to its supply, terminals
may be live and the opening of covers or removal of parts
except those to which access can be gained by hand is
likely to expose live parts.
The instrument shall be disconnected from all voltage
sources before it is opened for any operations. Operations
on the opened instrument under voltage must only be
performed by an expert who is aware of the hazard involved.
Capacitors inside the instrument may still be charged even
if the instrument has been disconnected from all voltage
sources.
Only fuses of the specified type and rated current may be
used as replacements. Makeshift fuses may not be used.
The fuse-holder may not be short-circuited.
Whenever it is likely that protection has been impaired, the
instrument shall be made inoperative and be secured
against any unintended operation.
It must be assumed that the protection has been impaired
when
−
the instrument has visible signs of damage,
−
the instrument no longer functions,
−
the instrument has been stored in unfavorable
conditions for a long time
−
the instrument has been subjected to adverse transport
conditions

If the controller is to be used for a measuring input other than the
one preset,
1. The soldered jumpers G2 and G5 must be closed or opened
in accordance with the following table or the resistor R1
should be installed or removed.
