CAUTION
Make sure that the connection between –V terminals is reliable to avoid disconnection
during operation. Disconnection may cause damage to the power supply.
NOTE
With local sensing it is important to minimize the wire length and resistance. Also the positive and
negative wire resistance should be close as possible to each other to achieve current balance be-
tween power supplies
