1.09 Power supply
GH3 is equipped with batteries that require regular recharging. The power
supply for charging and the battery charging point must be connected by a
qualied engineer or by Guldmann Service Team.
The transformer supplied must always be used.
Safety concerning static electricity (ESD)
Service technicians and installers must use an ESD-safety package
consisting of a mat, a ground wire, and a bracelet. The technician/installer
connects the mat to a grounding point, for instance a radiator or a water pipe.
The technician/installer must then put on the bracelet and connect it to the
mat. If it is not possible to nd a grounding point, the mat and the bracelet
must be used as a minimum.
Only then is it allowed to work with the PC Board or components where it
is possible to come into contact with the PC Board.
