B. MOUNTING BOXES (continued)
Note*: If Grid system accessories are to be fitted and the installation requires the attachment of conduit via nuts inside the mounting box, then it is recommended that a box depth of 47mm is used.
Some mounting boxes are fitted with additional threaded fixing lugs on the upper and lower edges. It may be necessary to bend these back into the box to allow the wiring accessory to enter the box to ensure the front plate sits flush to the mounting surface.
The metal flatplate ‘Modular’ wiring accessories range offers a variety of clip in modules, lighting switches- telephone data connectors, etc., providing the flexibility to customise a wiring device in the same enclosure and front plate. Care must be taken to ensure that segregation is maintained between modules of different operating voltages in accordance with regulation 515-01-02 of the 16th Edition of the IEE Wiring Regulations (BS7671).

C. GENERAL INSTRUCTIONS
IMPORTANT
Refer to safety instructions before starting work.
MK metal flatplate wiring accessories feature a high quality surface treatment to the front plates. To protect this surface during installation and subsequent building works, a protective cover is available from your local stockist. Instructions for use of this protective cover are printed on the cover itself.
Ensure the mounting box is firmly secured to the wall. Ensure minimum internal box depth is correct for the product with adequate space for cables.
Do not lose the front plate fixing screws provided with this product. The surface of the head of the screw is treated to compliment the finish of the front plate. To prevent damage to the screw head and front plate when fitting screws extreme care is required. It is recommended that a screwdriver with a maximum blade width of 3.5mm is used.
B. MOUNTING BOXES
The MK metal flatplate wiring accessories are designed to fit into folded metal boxes that comply with BS4662. To ensure products can be correctly installed, the box must always be installed flush or sub flush to the surface to a maximum depth of 6mm.
The recommended depth of boxes for the different types of wiring accessories are as follows.
• Socket outlets
• Lockable switchsocket outlets
35mm
47mm
• German style 2 pole + E socket outlet mounted in grid frame

When installing MK metal flatplate ‘Grid’ wiring accessories some extra precautions are necessary.
Ensure the grid mounting frame is marked with the identification letters ‘FP’. This is stamped into the front face of the frame.
(Note: standard MK GridPlus mounting frames are not suitable for installation of MK metal flatplate wiring accessories.)
The GridPlus modules may be clipped to the ‘FP’ mounting frame after assembling the mounting frame into the box.
Before attaching the front plate it may be necessary to set the height of the mounting frame by adjusting the fixing screws.
As a guide, the switch module shroud should be level with the face of the wall when front plate screws are tightened.
Correct adjustment will ensure the front plate is flush to the surface whilst gently clamping the modules in position.

D. CONNECTION
Load/Supply Cables
Strip back the sheath of the cable by the required amount.
Strip back the insulation of the individual conductors by the required amount (usually about 13mm).
Connect the conductors to the respective terminals. Pull on each cable to ensure that the terminal screw has securely fixed the conductor.
If the earth conductor is bare copper, ensure it is covered with a green/yellow sleeve, so as to ensure it cannot touch live parts.
Ensure all the terminal screws are tightened securely. Pull on each cable to ensure that the terminal screw has securely fixed the conductor.
When products have built in cord grip these must always be used to secure the flexible load cables emerging from the product. The cord grip must clamp the outer sheath of the cable.
