MAINS ELECTRICITY IS DANGEROUS!
Mains connection must be performed by a qualified electrician, in accordance with electrical wiring
regulations (BS.7671).
The earth connection must be correctly made to the centre terminal of the mains block, and to
terminal G1 of the End Station, and of any intelligent power supplies.
Metal lids must be correctly connected to mains earth by the wiring loom provided, before securing
in position.
Note: The PCB ground connection is NOT a safety earth connection, but is for EMC filtering
