Wiring The Unit
Sultan Acoustic Wave Series
Sultan SMART Units
The Sultan SMART unit has wiring information printed inside the lid of the unit.
Screw Cap Version
Unscrew the lid to expose the terminals. It is
recommended you remove the terminal block from
the unit before wiring - to do this, insert a screw driver
into one of the middle terminals to lever the block out.
Pass the cables through the cable entry gland before
wiring in to the terminal block.
Ensure the terminal is open by screwing counter
clockwise with a flat head screwdriver. Place the
exposed wires into the open terminals and tighten
until firm. Insert the block back into the unit when
wiring is complete. Press firmly on the plug in terminal
block to ensure it is fully home.
If you are connecting HawkLink communications,
connect the blue wire to B and the white wire to A.
The black wire can be connected to the DC- terminal
next to B.
Tighten cable entry gland(s) and cover to ensure
sealing is effective.
IP68 Sealed Cable Version
Connect the free ends of the cable following the wire
colours as shown in the terminal diagrams.
