Notes on electrical installation
When performing the electrical installation, it is important
to observe all valid national and regional regulations as
well as the provisions of the responsible electrical supply
company.
The electrical installation must only be carried out by a
qualified electrician who is responsible for compliance
with the existing standards and regulations.
5.1.2
Connection data
– The connected voltage and frequency must corre-
spond to the values stated on the rating plate.
– The electrical installation and any repairs may only be
carried out by authorised specialist personnel.
Use only original spare parts!
Install the pre-fuse cited in the Technical Specifica-
tions (circuit-breaker or slow fuse) to protect from
short-circuits.
– If several fans are operated on a single pre-fuse, ob-
serve the total connected load.
– The roof-mounted fan must be connected to the
mains via an all-pole disconnecting device to overvolt-
age category III (IEC 61058-1).
5.1.3
Overvoltage protection and supply line load
– The unit does not have its own overvoltage protection.
Measures must be taken at the supply end by the
switchgear manufacturer or operator to ensure effec-
tive protection against lightning and overvoltage. The
limits specified in standard UL/IEC/EN 60335-2-40
must be observed.
– The units are classified as overvoltage category III. The
mains voltage must not exceed a tolerance of ±10%.
5.1.4
PE conductor connection
The PE conductor must be connected to the PE con-
ductor system of the overall system.
5.1.5
Installing the power supply
Remove the mains connector from the packaging and
connect to the mains as shown in the connection dia-
gram.
Note:
The position of the roof-mounted fan in the
mounting cut-out is freely selectable. It
should be based on the position of the elec-
trical connection inside the enclosure.
Note:
No filter mats are needed in order to achieve
protection category IP 20.
Note:
Check that the clips are completely snapped
into place to ensure that the roof-mounted
fan is securely held in the mounting cut-out.
Note:
The filter mats may be removed to achieve a
higher air throughput. In this case, the pro-
tection category will be reduced to IP 22 and
UL Type 1.
Note:
Use only original Rittal filters which bear the
Rittal logo to be sure of the protection cate-
gory, air throughout and approvals.
Note:
You should inspect the filter regularly de-
pending on the amount of dust. Recom-
mended: Replace after 2,000 operating
hours at the latest, and as and when neces-
sary.
Note:
The side with the Rittal logo must be pointing
towards the fan.
Note:
The orientation of the cover on the base tray
is freely selectable.
