Wiring
Always disconnect the power supply to do the wiring.
The probes and their cables must
NEVER
be installed in a conduit together with power, control or power
supply cables.
For disconnection, the power supply circuit must be equipped with at least a 2 A, 230 V switch, located near
the device. The power supply cable shall be of the H05VV-F or NYM 1x16/3 type. The cross-section to be used
2
will depend on the local regulations in force, but must never be less than 1.5 mm .
2
Cables for relay or contactor outputs must have a cross-section of 2.5 mm and allow working temperatures equal
to or over 70 °C and must be installed with as little bending as possible.
The 120/230 V~ wiring area must be kept clear of any other external element.
The wiring to be undertaken depends on the option selected in the initial configuration wizard (see
p. 10). Use the appropriate diagram based on the option selected.
Check the available options on the diagram sheet included with your device.
The
AKO-16523D
model has a contactor which allows for the connection of three-phase defrost resistors, a three-
phase compressor or three-phase fans, according to your installation’s requirements. Check how to connect it on
the diagram sheet included with your device.
IMPORTANT:
Ÿ
The AUXILIARY relays are programmable, and their operation depends on the configuration.
Ÿ
The function of the digital inputs depends on the configuration.
Ÿ
The recommended currents and powers are the maximum working currents and powers.
