Fused Connection Unit (FCU) installer guide

Safety Warning 

The m.e Fused Connection Unit (FCU) shall be installed by a competent person, following all legal and good practice safety precautions in line with local Building Regulations. Please read the Installers Guide carefully and only install the m.e Power Socket in accordance with these wiring and safety instructions. 

Before commencing any electrical work ensure the supply is switched off at the mains, either by switching off the appropriate consumer unit or by removing the appropriate fuse. Wiring should be in accordance with the latest edition of the IET regulations (BS 7671). 

To prevent fire hazards always use cables of the correct rating, size, and type for the application. Any bare earth wires must be covered with appropriate green/yellow sleeving. 

Warning: do not exceed the 13A rating for the m.e FCU. 

Wire Identification 

Note - As of 1st April 2004 new colour codes for hard-wire installations were introduced. 

EARTH = Green/Yellow sleeving 

Neutral = Black (pre-Apr 04) / Blue (after Apr 04) 

LIVE = Red (pre-Apr 04) / Brown (after Apr 04) 

Product Overview 

The m.e FCU is a replacement for the standard 13A dual pole switched fused spur/FCU. The m.e FCU has extra functionality built-in, designed to make monitoring and control easier, automatically identifying and eliminating wasted energy and greenhouse gas emissions. 

Specification 

Installation 

1. Installers must be a Registered Competent Person and/or NICEIC Approved Contractor. Installers shall provide a suitable Risk Assessment and Methods Statement (RAMS) ahead of the works, along with a Minor Works Certificate (BS 7671) certificate upon completion. 

1. If replacing a fused spur with a m.e FCU, note the cable connections and wire the m.e FCU in the same way as the old fused spur. 

1. Ensure the mounting box for either flush or surface mounting is appropriately sized for the m.e FCU, at least 25mm in depth. 

1. Route the cable through the most suitable entry point of the mounting box. If a metal box is used, a protective cable grommet should be used. 

1. Cables should be prepared so a sufficient conductor length reaches the terminals. Strip the ends of the individual conductors so that an adequate length enters the terminals. 

1. Carefully arrange the wiring to lie along the edges of the mounting box, keeping the central area clear. 

1. When connecting the m.e FCU ensure that only the bare end of the wire enters the terminal, and no bare wires are visible. 

Always tighten the terminal screws securely, but do not over-tighten. 

An earth connection should always be made between the mounting box earth terminal, and one of the m.e FCU earth terminals. 

If the earth wire is bare, it is essential that it is sheathed with a length of green/yellow sleeving. 

1. Carefully position the m.e FCU into the mounting box, ensuring that no wires are trapped between the plate and the wall. 

Do not over-tighten the screws, ensure the button and isolation switch are functional. 

If supplied, fit screw covers. 

1. Once work has been completed correctly, replace the fuse for the circuit or switch the power back on. 

1. Test the m.e FCU as if it were a standard fused spur. 

1. Once power has been restored following installation, the m.e Impact Indicator will flash purple and then change colour depending on the client's set-up. 

The m.e FCU is now ready for use. 

Service Warranty 

The m.e FCU will perform materially in accordance with this documentation and Master Service Agreement, with replacement of defective hardware available. 

Environmental protection 

The m.e FCU should not be disposed of in general waste. Some chemicals contained within electrical products can be harmful to health and the environment. Only return m.e FCU to measurable.energy for reuse, repair, recycling or disposal. Your co-operation is vital for the protection of the environment.
