2.0 Installation
2.1 Important information for

2.2 Standard assembly kit
2.3 Installing the unit
1. Install the device in places where the
protection rating is observed and try not to
damage the box when drilling holes for wire/
pipe seats.
2. Do not use multi-polar cables in which there
are wires connected to inductive/power loads
or signalling wires (e.g. probes/sensors and
digital inputs).
3. Do not fit power supply wiring and signal
wiring (probes/sensors and digital inputs) in
the same raceways or ducts.
4. Minimise the length of connector wires so
that wiring does not twist into a spiral shape
as this could have negative effects on the
electronics.
For the purposes of assembly and use, the electronic AK-RC 111 control unit comes with:
• 3 seals, to be fitted between the fixing screws and the box back panel;
• 1 user’s manual.
Fig 1. Raise the transparent cover that shields the magneto-thermal cut-out switch and remove the screw cover on the
right-hand side.
Fig 2. Undo the 4 fixing screws at the front of the box.
Fig 3. To close the magnetothermic circuit breaker
transparent protection.
Fig 4. Open the front of the box, lift it and slide the two
hinges out as far as they will go.
5. Fit a general protection fuse upstream from
the electronic controller.
6. All wiring must be of a cross-section suitable
for relevant power levels.
7. When it is necessary to make a probe/sensor
extension, the wires must have a cross-
section of at least 1mm2. Probes extension
or shortening could alter their factory
calibration; therefore to check and calibrate
the probes through an external thermometer.
