6. Connecting to the Panel
All panel terminal block connections support cable with a maximum cross section capacity of 2.5 mm
2
capacity.
Care should be taken to use the correct sized terminal screwdriver and not to over tighten the screws.
If stranded cables are used then care should be taken to ensure that all strands are contained in the terminal
block and that there are not any loose strands that may cause short circuits to other terminals or cables.
The mains connection should enter the enclosure via a knockout as near to the mains terminal block as possible
and should be segregated from all other wiring. Mains connection cables should be kept short and be secured
together with a cable tie near the mains terminal block to minimise the danger of them shorting to other parts of
the equipment if they become disconnected.
The mains terminal block contains a F1.6A L250V fuse and must be replaced only with a fuse of the same type.
The diagram below shows the recommended cable routing for connections to the panel. The diagram shows the
rear cable entry points used. If top cable entry points are used then a similar arrangement should be employed.
To avoid the possibility of a confusing array of fault conditions, it is best to connect the system gradually so that
faults can be cleared on one circuit before connecting another.
Polarity must be observed carefully on any terminals with + or - markings and end of line devices must be fitted
to all circuits which connect to terminals that have had the supplied, end of line devices removed.
All wiring should be checked carefully before applying power to the control panel.
Do not connect or disconnect wiring with the power on.
