Any complaints have to be stated on the freight
document and countersigned by the driver!
In case of complaints please contact your distributor:
www.ormazabal.com
Remove the tightening straps. The circuit-breaker panel
is then no longer secured. Due to its design, the centre
of gravity of the circuit-breaker panel is higher than the
middle of the switch panel.
When handling the circuit- breaker panel in unsecured
condition the unit may tip over! Particular attention is
to be paid to this issue when transporting the circuit-
breaker panel to its place of installation. It not allowed
to use levers to transport the circuit-breaker panel to
its nal position. This action could cause damage to
the enclosure.
Eyebolts are tted to both sides of the gae.630 -1LSV panel,
which hold the panel safely in its position of centre of
gravity when transporting with chain or rope lifting gear
(Figure 3.2). Only transport cross members must be used
with this type of lifting gear. Otherwise there is a risk of
damage to the panel.
In some individual cases, the eyebolts are enclosed with the

Transport and installation
3.5. Installation and assembly
To install the circuit-breaker panel, use the installation plan
shown in Chapter 3.6.1. In order to assure secure standing
of the circuit-breaker panel use all fastening bores provided.
The depths of the individual panel types in the gae family
vary.
In order to ensure all possible block/ panel combinations
can be installed, the foundation projection must be drawn
at a distance of 135 mm from the wall!
On the variant with pressure absorber channel the minimum
distance is 100 mm.
If it is certain that during a system extension no:
•gae.630 -1LSFxx- panels
•gae measuring panels with metal cooling stretch are
installed, the distance from the wall can be reduced
to 100 mm.
To ease the assembly of the modular switchgear gae.630,
we recommend the following distances from side walls on
installation from left to right:
• Distance from left wall at least 100 mm
• Right wall distance at least 300 mm.
When installing from right to left the lateral wall distances
are reversed.
The area for the oor opening must not be reduced in
size, so that, in case of an arc incident, the hot gases
can be safely discharged.
A straight and level oor surface is a prerequisite for the
stress-free installation. Pay attention to the information
in DIN 43661. In particular the tolerance on the evenness
(maximum 1 mm over a measured length of 1 m) and
the tolerance on the straightness (maximum 1 mm per
metre and maximum 2 mm over the entire length of the
foundation rail) are to be observed.
To ease the assembly work on the installation of
several gae panels, we recommend the usage of a
metal chassis.
The fastening material is not part of the delivery.
To fastening the switch panel to a raised oor, we
recommend the following fastening material:
• Hexagon screw M10 (minimum M8, strength class 5.6)
DIN EN ISO 4017
• Washers DIN EN ISO 7093 (switch panel side)
• Washers DIN EN ISO 7089/7090 (raised oor side) or
tapered washers for fastening to U-sections
• Spring lock ring DIN 127 / DIN 128
• Hexagon nut M10 DIN EN ISO 4032
In the case of installation on concrete with a strength of
B ≥ 25 N/mm², we recommend the following fastening
material:
• Fischer plastic dowels of type S12
• Wood screw DIN 571-10x80-St
• Washer DIN 125 A10
To make the fastening bores accessible for installation,
remove the front cover (see Chapter 5) and if applicable the
cable xing irons of cable connection compartment.

3.6.3. Possible installations
Installationpossibilityforcircuit-breakerpanelsinaccessible
switchgear rooms.
During installation make sure not to damage the burst
protection in the bottom of the gas tank (Figure 3.5).
This diaphragm opens in case of an internal arc fault.
The gases emerging must be discharged as shown in
Figure 3.8.
As shown in Figure 3.8 the cable trench must have a dened
minimum cross section. For the optional pressure relief
of the cable trench the following rule of thumb must be
applied:
• up to 3 panels: 1 metal cooling stretch arrangement
(400 x 600 mm)
• from 4 panels: 1 second metal cooling stretch arrangement
of the same size
The metal cooling stretch arrangement provided by the
customer must be arranged in a way that the cable trench
is evenly divided.
Please ask for our assistance in the planning and installation
of the station.
The construction of the building and the switchgear
room must withstand the expected mechanical loads
and the internal pressure caused by a short- circuit arc.
Corresponding calculations for this are recommended.
Switchgear related pressure calculations can be requested
as part of the services provided by the sales department at
Ormazabal GmbH.

3.7. Installation of the supply line for the auxiliary and control circuits
There are openings for laying the supply line for the auxiliary
and control circuits in the roof of the relay cabinet.
Flexible plugs are tted in these openings, which provide
a cable bushing protected against dust and moisture. For
adaptation to the cable diameter use the separating lines
on the plugs.
The supply line from a neighbouring panel on the left or
right (loop cable) is laid through openings in the related
side wall on the relay cabinet (Figure 3.9).
If the relay cabinet on the neighbouring panel is tted
oset, the cable can be laid through the openings in the
roof of the relay cabinet (Figure 3.10).
