WARNING
To prevent electric shock that could result in injury or
death, NEVER handle a switching card that has power
applied to it.
Before installing or removing a switching card, make
sure the instrument is turned off and disconnected
from line power. Even when the instrument is powered
off, hazardous voltages may be present in signal
cables attached to the switch cards. Always disconnect
all cables before removing or installing a switch card.
If the switching card is already connected to a device
under test (DUT), make sure power is removed from all
external circuitry.
NOTE
For inexperienced users, disconnect DUT and external
circuitry from switching cards. This allows you to exercise
safe close/open operations without the dangers associated
with live test circuits.
WARNING
Slot covers must be installed on unused slots to
prevent personal contact with high-voltage circuits.
To install a switching card in a Series 3700A
instrument:
1. Turn the instrument power off.
2.
Position the instrument so that you are facing the
rear panel.
WARNING
As described in the International Electrotechnical
Commission (IEC) Standard IEC 664, the Series 3700A
switch cards are Installation Category O and must not
be connected to mains.
3.
Disconnect the power line cord and any other cables
connected to the rear panel.
4. Remove the slot cover plate from the slot. Retain the
plate and screws for future use.
