Drill the holes required to install cable glands or grommets.
Install the cable glands or grommets. They must comply with the switchboard’s
degree of protection (IP).
Refit the roof.
Run the cables through the glands or grommets.
Run the cables in the intended compartments and secure them to cable tie-bars
every 400 mm.
Crimp the lugs and connect.
When sealing does not call for cable glands or when sealing is achieved by means
of foam, cables can be routed in a rectangular cut-out in the roof. The removable
cross-member simplifies insertion of cables in the cubicle.

Drill the appropriate holes to assemble the cable glands or grommets (1-part gland
plates should not be drilled within 30 mm of the edges).
Install the cable glands or grommets. They must comply with the required degree
of protection (IP).
Refit the bottom plate.
Run the cables through the glands or grommets.
Run the cables in the intended compartments and secure them to cable tie-bars
every 400 mm.
If cable glands are not used, it may be easier to prepare the cable terminations
outside the switchboard (e.g. lug crimping) and then to drop them inside the cubicle
having first disassembled the bottom removable cross-member.
