X1 connector
Compact drives internally generate the 24 V DC necessary for the internal
circuits.
In regular operation, this voltage is obtained from the power bus and from
line voltage of the 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 entry
holes) and other data regarding the screw-on terminals of the plug-in
connector for X1 according to drive model:
