3.10.3 Remote sensing
Use rem ote sense where the load regulation at the load end is critical. In remote sense, the
power supply will compensate for voltage drop on the load wires. Refer to the power supply
specifications for the maximum voltage drop on load wires. The voltage drop is subtracted fr om
the total voltage available at the output. Follow the instructions below to conf igure the power
supply for remote sensing:
1. Ensure that the AC On/Off is in the Off position.
2. Remove the local sense jumpers from J2.
3. Connect the negative sense lead to terminal J2-5 (S) and the positive sense lead to terminal
J2-1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged se-
curely into the rear panel sense connector, J2.
4. Turn On the power supply.
Notes:
1. If the power supply is operating in remote sense and either the positive or negative load wire
is not connected, an internal protection circuit will activate and shut down the power supply.
To resume operation, turn the AC On/Off to the Of f position, connect the open load wire, and
turn On the power supply.
2. If the power supply is operated without the remote sense lines or local sense jumpers, it will
continue to work, but the output voltage regulation will be degraded. Also, the O VP circuit
may activate and shut down the power supply.

3.11 REPACKAGING FOR SHIPMENT
To ensure safe transportation of the instrument, contact the TDK-Lambda Americas Inc. sales or
service facility near you for Return Authorization and shipping information. Please attach a tag to
the power supply describing the problem and specifying the owner, model num ber and serial
number of the power supply. Refer to Warranty Information for f urther instructions.
WARNING
There is a potential shock hazard at the sense point when using a power supply
with a rated Output Voltage greater than 40V. Ensure that the connections at the
load end are shielded to prevent accidental contact with hazardous voltages.
CAUTION
When using shielded sense wires, ground the shield
in one place only. The location can be the power
supply chassis or one of the output terminals.
