X1 connector
Compact drives internally generate the 24 V DC necessary for the inter-
nal circuits.
In regular operation, this voltage is obtained from the power bus and from
mains when starting up the system.
It is a three-pin connector used to supply from mains the necessary start-
up energy.
The start-up process needs an internal module test prior to supplying power
to the upper terminals. Therefore, bear in mind the following warning:
Current from mains phases to these lines L1 and L2 must be obtained
from a point before the contactor providing the three - phase power to the
upper connectors of the compact drive.
The following table shows the values for gap, tightening torque (wire en-
try holes) and other data regarding the screw-on terminals of the plug-in
connector for X1 according to drive model:

Connector X1. 24 V DC.
WARNING. This internal power supply must be powered through connec-
tor X1 before carrying out any electrical maneuver.
