Rockwell Automation 440F MatGuard, 440F-C4000 Mat Controllers - Manual (Page 28)

Leave sufficient wire tail length to enable the connection to be remade if a mat is to be replaced, but
ensure that the interconnecting wires will fit easily under the edge trim without crushing. Join the wires
using butt connectors supplied as shown in Fig. 24 below. Where mat wires require extending, e.g. front
mat to rear mat connections, and control unit connections, use an extra pair of the butt connectors and a
length of twin wire (see wiring specification - section 6.2).

UNITING TRIM FIXING
All active uniting trim sections used in installation must be mitred to 45°. This aids in installation and
helps retain overall sensitivity of the sensing area.

PERIMETER TRIM FIXING
Where the wiring to the control unit is not buried, notch the perimeter trim at the wire entry and exit
positions and cut the trim slope to suit the conduit system selected. Take care to notch completely so
that any flexing of the perimeter trim will not trap the wiring. Ensure that there are no sharp edges or
burrs which could damage the wires.
