3.8.3 Wire Termination
The wires should be properly terminated with terminals securely attached. DO NOT use non-
terminated wires for load connection at the power supply.
CAUTION
Reversing the sense wires might cause damage to the power supply in local and remote
sensing. (Do not connect -S to +V or +S to -V.)
VORSICHT
Ein verpolter Anschluss der Fühlerleitungen an die Last, kann zu einem Defekt der
Stromversorgung sowohl bei lokalem als auch bei entferntem Sensebetrieb führen.
(Niemals die Anschlüsse des –S auf +V bzw. +S auf –V verschalten.)
3.8.4 Noise and Impedance Effects
To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted pairs
to the shortest possible length. Shielding of sense leads may be necessary in high noise
environments. Where shielding is used, connect the shield to the chassis via a rear panel Ground
screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to
reduce coupling, which might impact the stability of power supply. The sense leads should be
separated from the power leads.
