02.01 Intended use
Part of the unimes H power distribution system
The powerway enclosures are part of the unimes H power distribution system.
The unimes H power distribution system is a type-tested switchgear and controlgear assembly for
switchgear and controlgear assemblies according to EN 61439-1/-2/-5.

U-PWK
ACB compact coupling enclosure
Coupling enclosure for hw+ circuit breaker and load break
switch
Fixed indoor installation
The enclosure is intended for fixed indoor installation. It is permanently installed and operated in a
closed electrical operating compartment at the installation site.
Preventing operation by unauthorised persons
If the enclosure is not operated in a closed electrical operating site, switching operations and access
to the open switching enclosure by unauthorised personnel must be prevented. The enclosure must
then be lockable using a lock or tools must be required to open it.
Not to be operated by ordinary persons
The units are not intended to be operated or handled by ordinary persons.
Intended use also includes:
–Reading and observing the manual and unimes H system manual.
–Reading and observing this manual along with any instructions provided with the system compo-
nents (where available).
–Complying with the safety regulations.
02.02 Misuse
Misuse
Any use deviating from the intended use is considered misuse.
Hager does not assume any liability for damages resulting from misuse.
DANGER!
Danger due to electric shock or arc faults
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 provided in the Technical Data.
Observe the instructions for extension and the project planning rules.
Always observe the requirements for personnel qualifications.

02.03 General safety instructions
Electrical hazards
DANGER
Electric shock
An electric shock results in serious burns and life-threatening injuries and even death.
Prior to starting work on the system, observe the following 5 safety rules:
Disconnect completely (all poles and all sides).
Secure against reconnection.
Verify the absence of voltage.
First earth and then short-circuit.[1]
Cover or shield any adjacent live parts.
[1]
When working on low-voltage systems, the step for earthing and short-circuiting the system may only be omitted if
there is no danger of voltage transmission or feedback.
Minimum qualifications of specialist personnel: electrician / electrically skilled person with ap-
propriate testing experience
Only qualified electricians may select, assemble, install, operate, test, maintain, dismantle, and dispo-
se of components of the enclosure system.
Observe residual energies and static discharge
Prior to starting activities during installation work, disconnect the system and make sure it is statically
discharged before touching the devices. Static voltages can result in personal injuries.
Notes about connections, devices and functional earth
–The functional earth (FE) must be connected to the protective earth (PE) or the potential equalisati-
on. The installer of the switchgear and control gear assembly is responsible for establishing this
connection.
–Connection and signal lines must be installed so that inductive and capacitive interference do not
adversely affect the automation functions.
–The automation technology devices and their controls must be installed so that they are protected
against unintentional operation.
Ensure that the low voltage for the 24 volt supply features safe electrical isolation. Only power supply
units that fulfil the requirements of the IEC 60364-4-41 (HD 60364-4-41, DIN VDE 0100-410) may be
used.
Observe the tolerance of the mains voltage
Observe the specified mains voltage tolerances. Mains voltage fluctuations or deviations from
the nominal value may not exceed the tolerance limits specified in the technical data. If the tole-
rance limits are exceeded, functional failures and hazardous conditions cannot be excluded.
