The internal circuits of the non-regenerative power supplies PS-65A re-
quire an external 24 V DC supply. This is why its connector X2 has three
more pins than for the PS-25B4 power supply that integrates an auxiliary
power supply.
The internal circuits are protected with a 1.25 A fuse.
The following table shows the values for gap, tightening torque, sections
and other data of the plug-in connector for X2.
The next table shows the signals and other considerations related to each
pin of connector X2:
