2.1 Intended use
Hager’s tried and tested FWU field distributor and the univers FW internal fitting
system enable the implementation of switchgear and controlgear assemblies
according to EN 61439-3 “Distribution boards intended to be operated by
ordinary persons (DBO)”.
The Hager FWU field distributor can be expanded with components from the
univers FW internal fitting system.
Features of the FWU field distributor:
-for residential and commercial buildings with a maximum supply current of
125 A
-for flush-mounted installations, protected to IP30
-available in 6 heights and 3 widths
-mounting depth 110 mm
Fixed indoor installation/wall mounting
With its enclosed design, the FWU field distributor is intended for stationary,
indoor, flush-mounting in walls/hollow walls. The operating conditions for indoor
installation according to EN IEC 61439 and the maximum ambient temperatures
must be observed at the place of installation.
The FWU field distributor meets protection type IP30 when equipped with plain or
slotted doors. The instructions in this manual regarding compliance with the
protection type must be observed during installation work.
The FWU field distributor is available in protection class II (double insulated). The
instructions in this manual regarding compliance with the protection class must
be observed during installation work.
For more detailed information, refer to the technical data.
Further conditions for intended use
To use the enclosure as intended:
➢Read and observe the information in this manual.
➢Read and observe the instructions provided with the system components
(where available).
➢Comply with the safety regulations.

2.2 Misuse
Misuse
Any use deviating from the intended use is considered misuse.
Hager does not assume any liability for damages resulting from misuse.
Danger due to electric shock or arc faults in case of misuse
Misuse can result in high voltages and high currents, which can lead to
dangerous situations. This may result in serious injuries and even death.
➢Only use the product in areas for which the product is designed.
➢Never operate the product outside the specifications as provided in the
Technical Data.
➢Observe the instructions for extension and the upscaling regulations.
➢Always observe the requirements for personnel qualifications.
Limitation of operating areas
There are certain areas in which the FWU field distributor enclosure may not be
used, in order to prevent hazards or damage to the enclosure. The field
distributor is not suitable for use:
-in areas that require a higher protection type,
-in areas where ATEX directives must be observed,
-in operating sites at risk of fire,
-in corrosive environments. In particular, the enclosure and internal
components can become damaged if used in chlorinated, sulphurous, acidic
or saline environments.

4.1 Delivery form of enclosure (as a complete system or as
individual parts)
The FWU field distributor is supplied as a “complete” system or as “individual”
parts.
Complete system
Order number comprises wall cabinet, door and frame. With certain products
such as FWU52GS, the internal fitting system is already included.
In the case of empty enclosures such as FWU52D, there is no internal fitting
system included.
FWU52GS
FWU52D
Individual parts
To start with, the wall cabinet is ordered without a frame or door. The customer
must then order the frame, door and internal fitting system separately. This form
of delivery is particularly useful if the wall cabinet is to be installed at the building
site at a much earlier stage, or if a special door is requested which is not
available as part of a complete system (e.g. multimedia version).
For sizes 41, 42, 43, 51, 52, 53, 61, 62, 71 and 81, frames with a door come in
4 different versions. For all other sizes, the door and frame must be ordered
separately.
