Read these instructions fully before commencing work and retain 
them for future reference. 
SAFETY INSTRUCTIONS
These accessories are to be installed in accordance with the current 
edition of the IEE Wiring Regulations (BS 7671: Requirements for 
Electrical Installations) and appropriate statutory regulations.
In the Republic of Ireland the installation must be in accordance with 
the ETCI National Rules for Electrical installations – ET 101.
NOTE: IF YOU ARE IN ANY DOUBT ON HOW TO PROCEED, 
CONSULT A QUALIFIED ELECTRICIAN
Switch OFF the mains supply and remove the appropriate fuse or 
switch off the appropriate circuit breaker before commencing 
installation. Ensure that no one else has access that would enable 
the supply to be inadvertently reconnected.

SOCKETS WITH SCREWLESS DECORATIVE METAL 
FRONTPLATES 
Remove the clip-on frontplate by inserting a small screwdriver 
alternatively into the small slots (A) on the sides of the frontplate and 
gently prise off.
Once the socket is installed replace the screwless frontplate by 
clipping it back in place. Do this before reconnecting to the 
mains power.
To keep decorative metal frontplates clean, occasionally wipe the 
frontplate with a clean soft cloth. Do not use any form of cleaning 
agent as this could damage the decorative finish.

Install the socket as described in the following section, taking 
particular care to ensure the socket is correctly earthed. This is 
particularly important for accessories with metal frontplates.
Sockets can be installed using wall boxes with a minimum depth as 
specified below:
1 gang:  35mm (25mm with mounting spacer supplied) 
2 gang   25mm
Always use cable of correct rating and type. 
The socket can either be connected to a ring main circuit, in which 
case there will be a pair of twin and earth cables entering the box, or 
on a spur, which will only have one twin and earth cable entering the 
box.
THIS USB CHARGER IS PERMANENTLY CONNECTED 
EQUIPMENT. The circuit should therefore incorporate a readily 
accessible means for safely isolating the charger when required.
Strip the insulation from the Live and Neutral supply cables and 
connect the Brown (or Red) wire(s) to the terminal marked ‘L’ and 
connect the Blue (or Black) wire(s) to the terminal marked ‘N’.
Connect the earth wire(s) from the supply cable(s) to the earth 
terminal on the rear of the socket, and then connect a short length of 
wire from the socket earth terminal to the earth terminal in the wall 
box. If the earth wires are bare, they should be sheathed with a 
length of green/yellow sleeving. 
Ensure all the terminal screws are tightened firmly and are clamped 
on the copper conductors of each wire and not on the insulation. 
Locate the socket against the wall in front of the wall box, ensuring 
that the supply cables are not trapped by the front plate or within the 
wall box. Using the fixing screws provided, attach the socket to the 
wall box. Ensure the fixing screws are tightened securely.
Replace the appropriate fuse or switch on the appropriate circuit 
breaker. Switch on the mains isolator switch.
IMPORTANT NOTICE - WIRING COLOUR CHANGES
As from 1st April 2004 new installations in the UK could be wired 
using the new EU Harmonised colours for the supply conductors of 
twin and earth cable:
New colours  Brown = Live  Blue = Neutral 
Old Colours  Red = Live  Black = Neutral
The old colours ceased to be used after 1st April 2006.
Flexible cable colours remain unchanged:
Brown = Live  Blue = Neutral
Eire conductor colours for twin and earth cable and 
flexible cable:
Brown = Live  Blue = Neutral

NOTE
The USB connector is used for charging devices only, such as smart 
phones, tablets, cameras etc. When only one device is connected to 
a USB connector the total output current of 2.1A is available from 
either USB connector and when two devices are connected, the 
total rated current of 2.1A is divided between the two USB 
connectors.
The USB charging circuit within this device has both short circuit 
and overload protection. If the device is overloaded or short-circuited, the electronic circuit will limit or disconnect 
the output power to protect against damage or overheating. 
Once the fault has been cleared the circuit will re-set and power 
on automatically.
Some earlier model mobile phones and devices are not suitable 
for direct charging from a USB type charger and may not charge 
when connected to this product. These devices will require their own 
dedicated charger. Please check with your phone or device supplier 
for more information.
It is normal for the front surface of this product to become warm 
in use.
DO NOT MEGGER TEST this product as this could result in 
damage to the internal electronic components.
