CMW 500 Preparing for Use
Putting the Instrument into Operation
Operating Manual 1202.3986.32 – 03 13
ATTENTION
Operation in a rack
Allow for sufficient air supply in the rack.
Make sure that there is sufficient space between the ventilation holes and the rack
casing.
1.3.5 EMI Protective Measures
In order to avoid electromagnetic interference (EMI), the instrument may only be
operated when it is closed and with all shielding covers fitted. Only appropriate
shielded signal and control cables may be used.
1.3.6 Connecting the Instrument to the AC Supply
The R&S CMW 500 is automatically adapted to the AC supply voltage supplied. The
supply voltage must be between 100 V and 240 V with frequencies ranging from 50 Hz
to 60 Hz (see also the tolerances quoted in the "Specifications"). The mains connector
is located in the upper left corner of the rear panel.
Connect the instrument to the AC power source using the AC power cable
delivered with the instrument.
The maximum power consumption of the tester depends on the installed options. The
typical power consumption is also listed in the "Specifications".
The R&S CMW 500 is protected by two fuses located in the fuse holder to the right of
the AC power switch; see Replacing Fuses.
1.3.7 Power on and off
The mains connector is located at the bottom left corner of the rear panel.
To turn the power on or off, press the AC power switch to position I (On) or 0 (Off).
See also replacing fuses.
After power-on, the R&S CMW 500 is in standby or ready state, depending on the state
of the standby toggle switch at the front panel of the instrument when the instrument
was switched off for the last time.
The AC power switch can be permanently on. Switching off is required only if the
instrument must be completely removed from the AC power supply.
