The transformer is used as a power source for KR C2 cabinets which are connected to power supply
systems other than 400 V, or to 400 V networks without a grounded neutral.
The size of the transformer (8 kVA or 13 kVA) depends on the required power output!
Ordering information / limitations
The 8 kVA transformer must be used with drive configurations 1, 2, 5, 13, 15, 16, 17,18, 24.
The 13 kVA transformer should be selected
- if drive configurations 7, 9, 10, 23, 25, and 26 are used;
- if an external axis is used with KUKA Servo Drive KSD1-64 in the basic cabinet;
- if a top-mounted cabinet is used.
When using a basic cabinet in UL-version, an isolation transformer UL must be selected.
The primary voltage used must always be explicitly specified (see below).
If a transformer is to be used, a transformer installation kit must be ordered (see Transformer installation kit).
