Risk of damage!
Always connect each PxtRX active energy management device
via a two-pole fuse to the storage unit (DLCM, battery).
Mount the fuse as close as possible to the storage unit.
For parallel connection of several PxtRX devices with a common storage unit:
• The neutral point is the connecting terminal of the storage unit.
• Use a separate two-pole fuse for each PxtRX device.
• Use identical cabling for all PxtRX devices
(length, cross-section, routing, cable type).
Make sure that the storage unit (DLCM, battery) is compatible with the maximum

storage voltage set in the PxtRX.
Make sure that the storage unit (DLCM) is discharged or that the storage unit

(battery) is enabled.
Connect the negative pole to the storage unit (DLCM, battery) via a fuse with the

negative pole of the active energy management device (X5, pin 2).
Connect the positive terminal of the storage unit (DLCM, battery) to the positive

terminal of the active energy management device (X5, pin 1).
Twist single wires.
