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.
Fix the retaining clips to each end of each module and frame.
The module is now secure. The procedure is reversed in order to
remove a module.
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.

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 IET 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 with the 17th Edition
of the IET Wiring Regulations
†
is intended to maintain at all times
the CPC to ensure safety.
