• Power cables and signal cables must be laid in separate cable ducts.
• Securing/Useable cross-sections:
If possible, the cross-sections for connecting the PxtRX should be selected to
match the connecting cable of the frequency inverter.
If this is not possible, there are two options:
1.) Select a short-circuit-proof cable with reinforced insulation.
2.) Install an additional fuse in the supply line.
It should be noted that the energy storage solution is internally fused with 125 A.
An additional fuse must therefore be >125 A.

Connecting the DC circuit (DC link) (X1)

• The cable length must be shorter than 20 m.
• Single-wire conductor 0.75...16 mm² / 18...6 AWG
• Fine-stranded conductor 0.75...25 mm² / 18... 4 AWG
• Fine-stranded conductor, with wire end ferrule with plastic collar 0.75...16 mm²
• Fine-stranded conductor, with wire end ferrule without plastic collar 0.75...16 mm²
• Fine-stranded conductor, with twin wire end ferrule 0.75...6 mm²
