separate body and tank
”.
The following additional tools and equipment are required
to assemble enclosures with separate body and tank:
1
Spirit level.
2
EPDM adhesive strip (20 mm wide and 25 mm thick)
3

operational earthing circuit can be optionally installed.
These earthing circuits connect to the exterior earthing
networks.
The installer or final user must provide suitable safety
measures in order to avoid dangerous touch and step
voltage.
The installation project must include the section for
implementation of the earthing installation, along
with justification of sizing in accordance with local
legislation.
