Cables and Wiring

Power Cable
The unit comes with a UK plug end and a 110-240v supply, (The Smart Switch requires 8 to 55V
DC supply) to plug into a wall socket, we recommend you use an existing wall socket point or
create one from the Distribution board with a switch. If your country uses a different plug you can
keep the power supply and just get a cable with figure 8 C7 adaptor or replace the plug directly.
Ethernet Cable
Run the Ethernet cable between your ACES2 unit and the nearest internet access router so data can
be uploaded to the MQTT site and remote instructions can be sent to the unit.
Temperature Probe Extension Cable
Extend the temperature probe(s) up to 50m maximum, by using a 3wire (or 2 pair) screened
(shielded) signal cable (AWG26 or larger), connecting the temperature probe to the end via either
soldered connection or terminal block and put in the diode. Also ensure the screen is connected to
earth otherwise noise will effect the temperature probe!
If having more than 1 sensor, you must connect them in 'daisy chain' or line bus format and
not a star network. This means there only ever be 1 set of wires going to the ACES2 unit
(rather than each sensor wires return to the ACES2 unit which would form a star network).
You can connect the screen to earth by connecting to the Distribution Board
Earth bar or alternatively to the Eniscope Earth connector (but ensure the
Eniscope itself is connected to the Earth bar in the DB).
