Electronic Modules Ver. 0002 EM - 27
EM.3.3.2 CONNECTOR X1
Compact Drives internally
generate the 24Vdc necessary
for the internal circuits.
In regular operation, this voltage
is obtained from the Power Bus
and from mains when starting
up the system.
The mains energy necessary for
start-up is supplied via this
three-prong Phoenix connector.
The start-up process needs an internal module test prior to supplying power to the upper
terminals. Therefore, bear in mind the following warning:
Power from this internal power supply, through this connector X1, must be the very first thing
to do before any other electrical manoeuvre.
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. See
sample schematic of an electrical cabinet on chapter IN.
The Module is protected by 1 Amp fuses one per phase.
