device in parallel. Please note that PxtRX must always be used with the same settings. All PxtRX energy
management devices must have the same number and storage type of energy
modules or be connected to the same storage unit (DLCM, battery).
In the case of parallel connection, the devices must always be connected to each
other via the K-Bus communication interface (
Determine the polarity of the DC circuit (DC link) connections.
De-energise the DC circuit (DC link).
Ensure that there is no voltage in the DC circuit (DC link).
If accelerated unloading is desired, consultation with Michael Koch GmbH is
required.
Make sure there is no voltage between terminal "Drive +" (X1, pin 1) and terminal
"Drive -" (X1, pin 2).
Connect the negative pole at the DC circuit (DC link) output of the application in

management device.
Connect the positive pole at the DC circuit (DC link) output of the application in
loop through the ferrite sleeve
management device.
Supply the DC circuit (DC link) with voltage.
