HARDWARE
The internal circuits of the non-regenerative power supplies PS-65A require
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:
X3|X4|X5|X6 connectors
These connectors belong to the auxiliary power supply integrated into the
main power supply PS-25B4.
Connector X3 receives power from mains. It admits a voltage between 400
V AC and 460 V AC.
This auxiliary power supply generates 24 V DC and its purpose is to feed
the control circuits of the module itself. Also, it supplies up to 10 A of this
DC voltage through connectors X4|X5|X6. These three connectors are
identical and offer greater connecting flexibility.

INFORMATION. There is no need to install external protection fuses in
these power lines. They are already integrated into the power supplies.
