1.5 External Wiring

The picture below shows the terminal block positions for

each switch input.

Install cables suitable for the application and degree of fire

protection required. These circuits are SELV type.

If additional knockouts are required, use the deeper back

box (Mxm-020) or use the Termination Enclosures (Mxm-

028 or Mxm-029) as appropriate.

All electrical wiring installation work should be

carried out in accordance with the code of

practice applicable in the country of installation.

To maintain electrical integrity of the SELV

wiring on the input lines all SELV wiring should

be segregated from the LV mains wiring and be

wired using cable with insulation suitable for the

application.

To minimise the effects of EMC interference all

data wiring circuits should be wired with a

twisted pair of conductors with a cross sectional

area suitable for the loading conditions.

In areas where cabling may come into contact

with high frequency interference, such as

portable radio transceivers etc. the input wiring

cable should be of a twisted pair construction

within an overall screen. The screen should be

terminated to one of the dedicated earth studs

available in the panel (refer to panel manual for

positions).

NB: Minimum / Maximum cable size for all

connections is limited to 0.35mm² / 2.5mm² (22-

14AWG).
