Several ABAX 2 / ABAX wireless system controllers can work within each other's range. The
number of wireless devices working within each other's operating range depends on the
frequency of periodical communication. The higher the frequency of communication, the
lesser number of devices can work within each other's range.
4.2 Preparing the cabling
Run the cables to be used to connect the controller to the control panel or other devices to
the controller's installation location. For power cables, use flexible conductors with cross-
sectional area of 0.5-0.75 mm

. Do not lay the cables in immediate vicinity of the low-voltage
electrical network wires, especially those used for supplying the high-power equipment (such
as electric motors).
4.3 Installation of enclosure
Fig. 5. Opening the OPU-1A enclosure.
The ACU-220 controller is sold complete with the OPU-1A enclosure.
1. Loosen the screws locking the enclosure cover and remove the cover (Fig. 5).
2. Remove the fastening screws of electronics board and remove the electronics board.
3. Place the enclosure base against the wall and mark location of the mounting holes. Set
the enclosure so that the cable entry opening is situated at the bottom of the enclosure or
at the base.
4. Drill holes for wall plugs (anchors) in the wall.
5. Make the cable entry opening at the base. The opening diameter must be larger than
10 mm. The finished opening must not have sharp edges.
6. Run the cables through the prepared opening (power cables, cables connecting the
controller with the control panel or other devices, etc.).
7. Using wall plugs and screws, secure the enclosure base to the wall. Proper wall plugs
must be selected for the type of mounting surface (different for concrete or brick wall,
different for plaster wall, etc.). When installed, the device must withstand a pull-off force of
at least 50 N.
