connection
terminal
First, remove the short circuit bar between PD/+1 and P/+ terminal.
Then connect optional DC link choke for improving the input
harmonics.
P/+
G( )
Earth terminal
To make grounding. Be sure to make this grounding to avoid
electric shock, and for improving the EMC performance. The
terminal is located on the heatsink.

note )The voltage of P24 changes like the chart below by a load electric current. In the case of use, please be
careful about external equipment. (ext-operator:OPE-S/SR/SBK/SRmini)
As for this chart application, it is just for December, 2012 production.
Thereafter, all models become the curve to show in 015,022L/SB.
