4.4 Installation Requirements
4.4.1 On-site Logistics
General Information
In order to guarantee best practice and a short implementation period, certain requirements must
be fulfilled by the customer (or customer-assigned third-party vendors) prior to the Brainlab
installation. The following section gives a brief overview of the typical scope of work.
Wall/Substructure
Structural/static approval by licensed engineer.
Definition of Protective Earth, Functional Earth and Potential Equalization
PROTECTIVE EARTH (PE): Conductor to be connected between the PROTECTIVE
EARTH TERMINAL and an external protective earthing system (e.g., electrician
safety).
FUNCTIONAL EARTH (FE): Terminal, directly connected to a circuit or to a screen-
ing part, that is intended to be earthed for functional purposes (e.g., EMC, SHLD).
POTENTIAL EQUALIZATION: Conductor other than a PROTECTIVE EARTH CON-
DUCTOR or a neutral conductor, providing a direct connection between electrical
equipment and the potential equalization busbar of the electrical installation (e.g.,
compensation of voltage, single fault condition (SFC)).
Duct Work/Conduits
• Conduit implementation according to the Brainlab drawings
• Inner diameter: 40 mm (1.57") (unless nominated otherwise - refer to Brainlab drawings)
• All conduits to be prepared with pull wire
• Refer to schematics starting on for routing overviews.
