Rear inputs connections
SHOCK HAZARD
Turn off AC mains before connecting wires to the rear panel. All wires and straps must be properly connected
with the terminal block screws securely tightened.
SHOCK HAZARD
Floating voltage must not exceed 240 V
DC
. The total voltage on the input terminal and the floating voltage
must not be more than 240 V
DC
from chassis ground.
DONOTREMOVE THEMATINGCONNECTOR
Rear input terminal connection must be performed with the presence of mating connector.
The mating connector accepts wires sizes from AWG 14 to AWG 6. The mating connector is 60 A rated for the
EL34143A and EL34243A. Wire sizes smaller than AWG 14 are not recommended. Connect the DUT wires to the +
and - terminals. Connect the sense wires to the +s and -s terminals.
Securely fasten all wires by tightening the screw terminals.
Part number information for the connector kit is provided under Standard Shipped Items.
Wire sizing
FIRE HAZARD
Select a wire size large enough to carry short-circuit current without overheating (refer to the following table).
To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short-cir-
cuit output current of the DUT connected to electronic load.
