gangways according to IEC 60364-7-729 must be taken
into account when planning the space required (Fig. 8/2).
When using an lift truck for the insertion of circuit-breakers,
the minimum gangway widths must be matched to the
dimensions of the lift truck! Reduced gangway width
within the range of open doors must be paid attention to
(Fig. 8/3). With opposing switchboard fronts, constriction
by open doors is only accounted for on one side. SIVACON
S8 doors can be fitted so that they close in escape direc-
tion. The door stop can easily be changed later. Moreover,
the standard requires a minimum door opening angle of
90°.
Altitude
The altitude of installation must not be above 2,000 m
above sea level.
Switchboards and equipment which are to be used in
higher altitudes require that the reduction of dielectric
strength, the equipment switching capacity and the cooling
effect of the ambient air be considered. Further informa-
tion is available from your Siemens contact.
