Platform concept
A further innovation of the ALPHA distribution board product
range is the "platform concept", which means that all supporting
build-in components are mounted directly onto the platform (rear
plate).
The covering parts (side panels, roofing plates, base plates and
doors) are either assembled immediately or at a later point in
time, irrespective of the assembly kits. The fact that the quick-as-
sembly kits and assembly kits can be equipped and wired with
modular installation devices is an additional advantage.
The completely wired assembly kits can then be placed on the
platform and secured to the rear plate with a quick-acting lug. In
addition, the quick-assembly kits or assembly kits can optionally
be secured with a screw, which is included in delivery. The en-
closure covering parts such as top, base and side plates are
then mounted.
The available wiring space can be optimally utilized as the rear
plates of the modular installation devices can be manually ac-
cessed from all four sides.
The advantage of being able to fit the remaining parts of the en-
closure at a later stage also makes it possible to prevent dam-
age to the coating or other visual damage.
During the mounting phase, the platform can be optionally
mounted with or without the covering parts and doors. The com-
pletely equipped and wired assembly kits or quick-assembly kits
are then simply snapped onto the platform or in the pre-assem-
bled unequipped distribution board.
The completely equipped and
wired assembly kits or quick-
assembly kits are fastened directly
onto the platform (rear plate).
The front covers can now be
mounted.
The covering parts such as top,
base and side plates are then
mounted.
