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.
Use remote 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 specifications for the
maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage available
at the output. Follow the instructions below to configure 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.

.
Connect the negative sense lead to terminal J2-2 (-S) and the positive sense lead to terminal
J2-3(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely
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 Off 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 OVP 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 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 number and serial number of
the power supply. Refer to Warranty Information for further instructions.
