RMX Programmable Power Supplies User Manual
Sensing
When RMX programmable power supplies are shipped from the factory, the connector is
attached to the sensing terminals. RMX programmable power supplies are supplied with a
connector cover that fits over the entire sensing, J1, and J2 connectors. For safety reasons,
be sure to attach the connector cover when you use the RMX programmable power supply.
If they are damaged or lost, contact National Instruments.

Caution
Risk of electric shock and damage to internal circuits.
Never wire the sensing terminals while the POWER switch is turned on.
Use sensing cables that provide reinforced or double insulation with a capacity
greater than or equal to the isolation voltage of the RMX programmable power
supply. For uncovered sections of the shielded cables, use insulation tubes to secure
reinforced or double insulation with a capacity greater than or equal to the isolation
voltage of the RMX programmable power supply.
The sensing terminals are at approximately the same electric potential as the negative
output terminal. Insert the cables so that the wire strands do not touch the chassis
when they stick out of the sensing terminal. Also, insert the cables so that the stripped
wires do not stick out of the terminal.
