Installing Modules into the Cablelink Plus Modular
Floorbox
To install a module into the Cablelink Plus Modular Floorbox, firstly ensure
the sliding bracket is pushed towards the centre of the module.
1
Lower the opposite end into the box and push the tab firmly into the
slot in the ladder at the height the module should be positioned.
The other end is then lowered down so that the tab on the sliding bracket is
level with the same slot on the other side of the frame.
2
Holding the module with the built in handles, the sliding bracket is then
pushed outwards so that the tab engages with the correct slot.
A screw is then used to fix the sliding bracket in place.
The module is now secure. The procedure is reversed in order to remove a
module.

Dual Earth Sockets and High integrity Earthing
†
Modern offices, schools, universities, laboratories etc, are heavy users of IT,
computing and electronic equipment. As most of this equipment is fitted
with a filter mechanism to protect data and data transmission against RFI
and power surges, small earth leakages emanating from this equipment
introduces a current onto the Circuit Protective Conductor (CPC) effectively
turning this into a functional earth.
Should the CPC be broken, any equipment downstream of the break is no
longer connected to earth. If a fault now occurs in this equipment, the
CPC could rise to the mains potential and the fault transferred to other
equipment on the circuit. The implicit risks to equipment, data and most
importantly users in this situation are dealt with in the 17th Edition of the
IEE Wiring Regulations
†
,
and have led MK Electric to introduce Dual Earth
Sockets.
Dual Earth Sockets allow the designer and installer to maintain the earth
integrity of the system, in accordance the the 17th Edition of the IEE Wiring
Regulations
†
is intended to maintain at all times the CPC to ensure safety.
Clean Earth Sockets
Clean Earth Sockets allow the designer and installer to introduce a protective
conductor connecting sensitive equipment i.e. a computer, directly to the
main earth.
This reduces the possibility of ‘noise’ occurring on the protective conductor
through induced voltages from other equipment, and hence can have
benefits in maintaining data and data transmission integrity.
Earthing on Data modules for Modular Raised
Earthing studs are provided on all Unserviced data modules to enable a
reliable connection to earth to be made. Earthing Kit CX-10 is recommended
for use to ensure the earthing cable is connected correctly.
