OPERATING INSTRUCTIONS
AH2A1 can operate as a Slave device only, i.e. an expansion unit. It can be controlled
via Modbus or, in case you do not intend to use Modbus, you can set it via the DIP
switches (see
Fig. 5
below). AH2A1 needs to be connected to an external master
controller in order to operate.
Follow these steps (see Fig. 3):
1.
Connect the mains supply to L, N and Pe.
2.
Connect the heater to the output terminal block - terminals N and H.
3.
Connect the unit to a master device (e.g. AH2C1-6) via inserting the low voltage
cables through one of the cable glands and connect them to GND and Ai1 of the
terminal block.
