3.2.4
Setting up the unit
The Xiria system has been designed in accordance with
the recommendations set out in IEC 62271-200 which
theoretically prevents internal faults from occurring.
Moreover, when set up correctly, a Xiria unit will comply
with this IEC standard for setting up with an arc channel.
The pressure relief flaps in the Xiria enclosure are located
at the rear and bottom of the unit, and they can be
connected to the arc channel of the building.
The pressure relief flaps at the rear can be sealed off using
a cover plate available separately as an option.
For further information see also the floor plan drawings in
Appendix 1.
The following rules apply to a set-up with an arc channel:
The channel is to be connected to a location where no
danger can occur to personnel.
The bore of the channel is to be a minimum of 0.15 m
2
and the channel itself requires to be capable of
withstanding overpressure of at least 0.5 bar.
The area the arc channel is connected to must be
capable of withstanding the overpressure also.
3.2.5
Securing to the floor
The Xiria unit must be fixed to the floor in four locations.
The drilling pattern for fixing and cable holes is included
in Appendix 1, 'Floor plan'.
Use washers under bolt heads/nuts.
3.3 Connecting the cables
3.3.1
Types of cables
Single-core cables can be connected to the unit.
Three-core cables can be connected, if the dimensions of
the associated splitting point fit into the cable compartment.
