Powerlink PlusTechnicalSkirting and Dado Trunking System
DescriptionPowerlink Plus is a trunking distribution system which contains within its profile a 63A single phase set of busbars and facilities for carrying telecommunications and data services cables.
Co-ordinated within the system is a wide variety of electrical and extra low voltage (ELV) outlets.
On the mains side these include specially designed sockets, both switched and unswitched, nonstandard switchsockets, switches, connection units and, via a simple interface, facilities for mounting all standard MK outlets.
ELV outlets include a master telephone socket outlet, an isolated co-axial socket outlet, “handset” telephone linejack outlet, computer sockets, a blank box and cover to accommodate other ELV requirements and, via a simple interface, facilities for mounting all single gang, standard MK ELV outlets. Also available are BNC type, LJU6C/RJ45 outlets, Euro Outlets and a blank to accommodate other ELV requirements. Incorporates a ‘Stay-set’ mechanism and is mains failure proof, ie it will function under all the normal conditions expected of an RCD and will not trip in the event of a power cut. This makes it suitable for use with freezers or in inaccessible or unmanned locations.
FEATURES
l Wide variety of visually and physically compatible mains and ELV outlets
l Complete segregation between mains and ELVl Stylish and elegant appearancel Easy to assemble, extend and modifyl Durable and impact resistantl Attractive stylingl Suitable for skirting or dado mountingl 3 compartment trunkingl Manufactured to high precision standardsl All extrusions manufactured from 100%

GENERAL NOTES
Prior to installation strike a line of trunking using a plumb and chalk line for vertical, and spirit levels for horizontal runs.
Surface track accommodates 63 amp busbar with an integral duct directly above mains.
Data and Telecom cables.
Pre cut slots and circular holes at 100mm centres permit fi xing holes to be drilled and a wallplug with screw inserted after the surface track has been positioned.
When fi xing trunking use bushes provided and No. 8 wood screws.
Ensure trunking base is secured within 100mm from the end and a maximum of 500mm apart on either side along the length.
Check levels frequently – particularly at corners.
Debur all cut ends using a fi le or a sharp knife.
For mini trunking adaptors drill a 20mm diameter hole through the wall of the centre compartment using drill guide. Insert the tunnel and fi x with two screws provided.
Bridging busbar compartment – if required to take cables from top compartment to bottom or vice versa – drill holes to align with top and bottom holes of the centre compartment. Cut out 85mm from the busbar at the required position. Install cable link (1919) to the busbar and snap fi t cable crossing barrier (K1937CHA) over cables.
Commence installation at cable entry position. Route cables into the central section, wire in to the selected cable termination and plug into adjacent busbar and secure with screws supplied.

Installation Guide Continued Cut central cover to length to fi t exactly between the exposed frontplates of accessories. At coupling positions leave expansion gaps by cutting the central cover to the same length as the trunking base.
Secure centre covers to the main base with the screws provided every 500mm max, top and bottom and within 150mm of accessories and fi ttings.
At the junction of two adjacent lengths of trunking busbar plug in the coupler to maintain electrical continuity. It is fi tted over a protector in the coupler carrier.
Data / Telecoms Devices – Secure enclosure box over centre compartment with screws supplied.
Run cabling into enclosure and terminate onto outlet on frontplate. Secure front cover to enclosure box with screws provided.
Internal and external corners – Connect the lengths of busbar using the cable link assembly (1919) and
secure trunking using the screws provided.

17 Moulded corner and coupler shields should be fi tted before fi tting any covers. They are secured by the central covers overlapping each side of the component and do not require additional fi xing.
Powerlink Plus Sockets – Plug the socket onto the busbars in the required region ensuring that the socket clips fully locate fi rmly on to their corresponding busbars. Secure with screws provided. Note – do not tamper with busbar clips.
Plug on connection units – Connect the load conductors which are either routed through the centre compartment of the trunking or enter through the fl ex outlet. Plug connection unit onto busbar where required and secure as described above.
Outer Covers – For central covers and end cap retainers, leave a gap of 8-10mm and snap fi t onto
trunking.
Snap fi t end caps then other trims after fi tting all central and outer covers.18
