MAF RDU MAINS WIRING
The mains (240Vac) supply must be connected by a qualified electrician in accordance with
AS1670.1 and AS3000 regulations.
Ensure the mains cables to the RDU are isolated at the Distribution board
before connecting to the RDU.
The mains cable connects to the 3 way terminal block mounted on the cabinet rear behind
the mains cover.
(a)
Remove the mains cover with an M4 nut driver.
(b)
Shape the mains cable to clear the top of the cover, cut to length and strip only
20mm of the PVC cable sheath.
(c)
Connect the wires:
blue (black) to N
brown (red) to A
green (green/yellow) to E
Take care when stripping not to "nick" wires.
(d)
Cable tie the cable to the cabinet.

Refit the mains cover with the M4 nuts and shake-proof washers (note that these
earth the cover).

MAF RDU LED DISPLAY INSTALLATION
When internal LED Displays are required, the 4U x 80 zone or 7U x 64 zone inner door is
fitted to the cabinet directly below the 4U Operator Display with the M6 screws, washers and
cage nuts provided. The hinge is on the right hand side. Click the cage nuts in from the
inside.
The flat M6 washers have a sharp edge and a rounded edge. Fit washers to the screws with
the rounded edge facing the metalwork (to avoid damaging the paint).
The Display Bds mount to the inner door on the standoffs supplied.
Fit the FRCs and mini-jump link as shown in Fig 8.2.1.
The 2-wire LED Display power leads from the MAF/PSU should be fitted to one board in
every four, e.g. 1 per 7U inner door.
For New Zealand operation, the Display Extender Board connects to the last 16 zone display
board (if any) or directly to connector J13 on the controller if there are no display boards.
Refer to section 8.4.
