6.4.4. Mains Switch and fuse
The mains power voltage indicated on the instrument must correspond with the local supply voltage (mains voltage: 85–265
Vac, universal power unit, mains frequency: 50–60 Hz). Use cables of sufficient current capacity.
Figure 21 - Mains Switch, fuse holder and power
input
To replace a fuse:
1) Disconnect the mains cable
2) Pull the fuse holder out of the connector
3) Remove the damaged fuse(s)
4) Insert 1 or 2 fuses (4 A / 115V and 2 A / 230 V slow blow)
5) Replace the fuse holder
6) Plug the mains cable into a power outlet with a solid ground
connection
7) Switch the system on and operate as instructed in this manual
6.4.5. Connecting the generator to the ground reference
The earth connection to the GRP should be low inductive and low ohmic. The cross-section of the earth connection should be
at least 6 mm2. A braid of stranded wire or a flat copper or brass strip is better.

Connection to reference ground
For burst tests, the generator must be placed on a ground reference
plane which is connected to ground.
A low inductive high frequency ground connection between the test
system and the ground reference plane (GRP) is absolutely essential for
performing burst tests correctly.
