Chapter 11 Technical Data
3.1.6.2 Fusing
Pay attention to the correct fusing of the power supply when connecting the System
6844(RC).
The corresponding performance data can be taken from the equipment nameplate. The Sys-

40VA.
If the internal fuse (device protection) trips it is highly probable that the
equipment is faulty. In this case the device should be checked in the facto-
ry.
