3.3 Jumper Settings
The jumper positions B53 to B69 are located on the rear side of the PB-SIO4A and are
solder bridges. Jumpers B51 and B52 are located on the front side of the PB-SIO4A and
if installed are wire bridges. They are set at the factory as required and should not be
changed.

Note!
Before operating the PB-SIO4A ensure that the B51 and B52
jumper settings are set correctly according to the application. No
external VCCext may be applied to the non-optocoupler version,
and, correspondingly, external VCCext must be applied to optocou-
pler versions.
