Intended use
The PDU is used, in particular, for distributing power in IT racks and is envisaged for permanent instal-
lation in IT racks. It must not be used at locations where children may be present and is envisaged for
use only in a restricted access area (e.g. lockable rack).

Assembly notes
The PDU is assembled with the aid of the supports included in the accessories. The unit can be mount-
ed either at the front or rear, left or right of the IT rack.
Compact horizontal PDUs are designed for installation within the 482.6 mm (19") level. The required
assembly components for simple mounting are included with the supply. Depending on the type and
design of the IT rack, the PDU may also be fitted at the side of the 482.6 mm (19") level, as well as
vertically on the frame section of the IT rack. In such cases, additional assembly components may be
required which are
not
included as part of the PDU supply.

Installation and operation
Connect the PDU to the protective-earth conductor in the electrical system of the building.
Connect the PDU to a power supply with TN-S network configuration. Please note the detailed infor-
mation in section 6 "Technical specifications".
Note:
Rittal recommends always attaching the brackets to the PDU first, and then securing the
assembled unit to the inside of the enclosure. This means that the distances between the
brackets and hence the mounting points inside the enclosure are pre-defined, allowing
you to promptly identify any potential collisions of the PDU inside the enclosure.
Note:
Select the mounting point (position and spacing) for the two universal supports inside the
enclosure so they match those of the fastening pieces mounted on the PDU.
Note:
Ensure that the PDU is connected permanently to the mains power and does not have a
main switch for the all-pole mains power decoupling.
