Connections and wiring
WARNING
The following information is intended for qualified service personnel.
Do not make or break switching module connections unless qualified
to do so.
To prevent electric shock that could result in serious injury or death,
adhere to the following safety precautions:
•
Before removing or installing the switching module in the main-
frame, make sure the Model 2750 is turned off and disconnected
from line power.
•
Before making or breaking connections to the switching module,
make sure power is removed from all external circuitry.
•
Do not connect signals that will exceed the maximum specifica-
tions of the Model 7700.
If both the front panel terminals and the switching module terminals
are connected at the same time, the test lead insulation must be rated
to the highest voltage that is connected. For example, if 1000V is con-
nected to the front panel input, the test lead insulation for the switch-
ing module must also be rated for 1000V.
Dangerous arcs of an explosive nature in a high energy circuit can
cause severe personal injury or death. If the multimeter is connected to
a high energy circuit when set to a current range, low resistance range,
or any other low impedance range, the circuit is virtually shorted. Dan-
gerous arcing can result even when the multimeter is set to a voltage
range if the minimum voltage spacing is reduced in the external con-
nections. For details to safely make high energy measurements, see
“High energy circuit safety precautions,” page 3-3
As described in the International Electrotechnical Commission (IEC)
Standard IEC 664, the Model 2750 is Installation Category I and must
not be connected to mains.
