mation in section 8 "Technical specifications".
Depending on the PDU version, provide the following pre-fuse:
– PDU international: 3 x 16 A (3~/16 A versions), 3 x 32 A (3~/32 A versions), 1 x 16 A (1~/16 A ver-
sions) or 1 x 32 A (1~/32 A versions)
– PDU UK: 1 x 16 A (16 A versions) or 1 x 32 A (32 A versions)
– PDU UK: 1 x 13 A for PDU with BS 1363 (UK) plug
Route the PDU connection cable out of the IT rack and connect it to the mains supply.
Once connected, the multi-LED for the status display illuminates continually (fig. 16, item 3). The
LEDs of the CAN bus connections (fig. 16, items 1, 2) are flashing green or red.
Connect a connection cable from the Rittal accessories to a free slot on the PDU and the equipment.
