AMETEK CTS
6.3.4.
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).
WARNING
Mains Switch, fuse holder and power input

Connecting the burst NX8 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.

Fuses for EUT with smaller nominal currents
The AMETEK CTS pulse generators have no built-in fuse for the EUT power supply. It is in the scope of responsibility of the
user to protect the EUT external for the rated current.
The design of the external fuse must be match the following rules:
- fuse dimension must be equal or smaller than the rated EUT current of the connected test generator
- fuse must be designed for protect the connected EUT device under test in malfunction
Do not replace the supplied power cord, rated for 10 A with another power cord of
insufficient size.
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
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.
