*To ensure a reliable strain relief, individual wires must be laid especially for connecting the 15 and 20 kVA UPS systems.

Recommended connection cable acc. to VDE 0298-4:

Specially for 15 and 20 kVA: Special rubber-insulated wire NSGAÖU or NSGAFÖU

or NYY or

Radox 4GKW-AX e.g. Huber & Suhner

Alternatively, the 10 kVA UPS system can also be connected via a multi-wire rubber-sheathed cable.
