PROPlus electronic control panel
Electronic power control panel with a magneto-thermal protection cutout
switch for electrical control and operation of refrigeration services consis-
ting of a single-phase condensing unit, single-phase evaporator fans, sole-
noid valve, air or electric defrost (single phase), interior light and electrical
compressor sump heating resistance.
Incorporates graphic display, temperature register (1 channel), switch for in-
terior light, buzzer and relay alarm signal.
1- Warnings
Using the AKO-15640 without following the manufacturer’s instructions may alter its safety require-
ments.
To ensure correct operation of the apparatus, only NTC type probes supplied by AKO should be used.
Between –40 °C and +20 °C, when the probe is extended up to 1000 m with minimum 0,5 mm²
cable, deviation will be less than 0.25 °C (probe extension cable ref. AKO-15586)
2- Installation
The AKO-15640 should be installed in a place protected from vibrations, water and corrosive
gases, and where ambient temperature does not exceed the value specified in the technical data.
In order for the controllers to have IP65 protection degree, the gasket should be properly installed
between the apparatus and the perimeter of the panel cut-out where it is to be fitted.
In order to give a correct reading, the probe should be installed in a place without heat influences
other than the temperature that is to be measured or controlled.
2.1 Wall Mounting
- Remove cover T from the unit (Fig.1)
- Open the unit and separate the front part of the housing (Fig.2).
- Drill the holes for the glands required for the cables to pass through, guided by the pre-cut
centres in the sides of the housing.
- Drill 3 holes in the wall to match anchoring holes 1, 2 and 3 on the housing (Fig. 3).
- Insert the glands in the unit.
- Insert and tighten the 3 screws + plugs through the housing, into the 3 holes drilled in the wall.
- Pass the cable through the glands.
- Connect wiring specified on paragraph 2.3.1.
- Mount the front part on the housing (Fig.2).
- Insert and tighten screws D and F (Fig. 1).
- Connect wiring specified on paragraph 2.3.2.
- Close cover T, insert and tighten screws A and C (Fig. 1).
2.2 Panel Mounting (maximum panel thickness: 3mm)
- Remove cover T from the unit (Fig.1)
- Open the unit and separate the front part of the housing (Fig.2).
- Replace the seal installed at the front with the panelling seal, ensuring that it is in the right
position.
- Cut a hole in the panel with the described dimensions. (Fig.4)
- Drill the holes for the glands required for the cables to pass through, guided by the pre-cut
centres in the sides of the housing.
- Finish drilling holes G and J using a 4-mm bit. (Fig.3)
- Insert the glands in the unit.
- Pass the cable through the glands.
- Connect wiring specified on paragraph 2.3.1.
- Attach the front to the housing, through the panel and tighten the 45-mm screws through
holes D, E, F, G H, J (Fig.1 and Fig.3).
- Connect wiring specified on paragraph 2.3.2.
- Close cover T, insert and tighten screws A and C (Fig. 1).
2.3 Connection
CONNECT THE BATTERIES PRIOR TO STARTING UP THE UNIT
The probe and its lead should NEVER be installed in the same ducting as power or control cables.
Always disconnect the power supply when making the connections.
The power-supply circuit should be fitted with a main switch and residual current protection out-
side the panel.
Power supply cables should be H05VV-F 2x2.5 mm² or H05V-K 2x2.5 mm².
IMPORTANT: The function of every probe entry depends on its configuration (See ta-
ble “Assignment of entries”).
To obey EN12830 you must configure the control probe and the register probe seperatly.
2.3.1 Connect before closing the front part
2.3.2 Connect after closing the front part
WARNING: Be sure to disconnect mains power before performing any operation in
these terminal strips; connectors from 33 to 43 may contain voltage.

9- Mounting warnings and electrical diagrams
WARNING!!
Disconnect mains power before performing any operation inside the electric panel.
All wiring must comply with the regulations in force and must be performed by authorized
personnel.
Perform only the connections described in the electrical diagrams.
Use of the electrical panel contrary to the manufacturer's instructions may affect its safety
requirements.
Working ambient temperature: 0 ºC to + 50 ºC
Assigned insulation voltage Ui = 440 V~
Electric panels with IP65 protection degree
CEM 1 environment
Connectors for copper conductors
Resistance to short circuits Isc=4,5 kA
Panel installation:
Do not knock or perform rough movements in the panel.
Perform connections according to installation manual.
The probe and its lead should NEVER be installed in the same ducting as power or control
cables.
The earth connectors in the panels are installed to ensure continuity of the earth connection;
however, the earth connection is not made by the connector and should be made outside the
panel.
The neutral systems are TT or TNS type. The IT system cannot be used. The magneto-thermal
protection cutout switches are phase/s + neutral, C curve, ensuring sectioning and protection
against voltage spikes.
Close panel when not working on it.
