If the wire shield needs to be grounded at the
voltage source (EXT-V), then the shield cannot
also be grounded at the negative (-) terminal
output of the PSW power supply. This would
short the output.

 Pin16 → EXT-V (-)
 Pin5 → EXT-V (+)
 Wire shield → EXT-V ground (GND)
Steps
1. Connect the external voltage according to the
connection diagrams above.
2. Set the F-91 power on
configuration setting to 1 (CC
control – Ext voltage).
