Rockwell Automation 440F MatGuard, 440F-C4000 Mat Controllers - Manual (Page 29)

Mark out the edge trim fixing positions on the floor allowing the trim to overlap the mat. Using the holes
in the trim as a guide, mark out and drill the floor (fit plugs if required). Clean off the floor and fix the
mats and edge trim in place using countersunk screws to suit the application.
As the perimeter trim is fitted ensure none of the wiring is trapped or crushed between the trim and the
floor or the top and bottom sections (depending on trim type).
If there is a possibility that the wires may be caught or pulled, a strain relief clamp should be used where
the wiring exits the perimeter trim. All wiring should be protected in suitable conduit. If possible, the
wiring/conduit should not cross a floor area where it will be a tripping hazard. If it is not possible to avoid
this, the wiring/conduit should be enclosed within our Protective Wire Guide 440F-T3230 (see Available
Spares on page 37).
6.2 CONTROL UNIT INSTALLATION AND WIRING (also refer to section 4 fig. 7, section 5.3.7
and section 5.7)
The control unit should be installed as supplied. It must not be modified or subjected to any procedures
or connections other than those described in this manual.
Prepare the control unit by carefully knocking out (440F-C4000P) or drill out (440F-C4000S, 440F-
C28013) the cable entry positions to be used. The input power supply must be separately routed and
enter the control unit via a separate entry to those used for the output wiring. Mount the control unit in its
planned position. All wiring to the control unit terminals must use either wire type supplied or multistrand
conduit cable/ switchgear cable/ equipment wire with 0.5 - 1.5mm
2 conductors. Cable entry into the
control unit (440F-C4000P, 440F-C4000S & 440F-C28013) must be achieved using glands or adaptors
which provide an ingress protection rating of IP65. Ensure that the glands or adaptors are of a suitable
size and are fully tightened.
The insulated pin crimps supplied must be used. This wire and terminal combination avoids the
possibility of shorts from loose strands or open circuits caused by overtightening or vibration.
Ensure that a suitable ratchet type crimp tool is used. Crimp onto both the conductor and the insulation.
Do not connect more than one wire onto one crimp.
ENSURE THAT THE POWER SUPPLY REMAINS ISOLATED AND LOCKED OFF UNTIL
SECTION 6.4.
The mains AC supply must be externally fused at the point of supply by a 500mA max. high rupture
capacity (HRC) fuse. Unless the neutral side of the supply is referenced to earth, it must be fused to the
same specification.
