6.1.4 Connection diagram ZN045 EC-fan 200-277 V AC ~1 50/60 Hz
Figure 21: Connecting diagram ZN045-6IL
The power cable for the ZN045 is an 1-phase cable. This power cable must be connected to the
following terminals inside the terminal box of the fan (see Figure 21):
− Live-wire (brown) to ‘L1’
− Neutral-wire (blue) to ‘N’
− Earth wire (green/yellow) to ‘PE’
The main voltage where the EC-Fan is connected to must be corresponding to the voltage which is
given on the type plate/sticker on the side of the fan. This main voltage must meet with the quality
characteristics of EN50160 and the defined voltages of IEC60038.
The digital input (D1) is the external start on which the fan is turning on and off. When the terminals
‘D1’ and ‘DC Out’ are connected, the fan is enabled to switch on and off. The fan will operate
following the preferred speed. The applied wire diameter is dependent on the length of the wire.
It is possible to regulate the RPM of the ZN045 by an external signal. The advice is to use a shielded
cable for this external signal. There are multiple options to apply as an external signal:
−
0…10V + on E1,
−
on GND
− 0…100% PWM + on E1, − on GND
− Potentiometer + on 10V, − on GND and the signal on E1
The ZN045 EC-Fan is equipped with the possibility of MODBUS communication with a RS-485
interface. To use the MODBUS communication, terminals ‘A (D+)’ and ‘B (D - )’ must be connected. In
the case of attaching multiple fans to each other with MODBUS, this must be done in a serial circuit
like it’s done in the following figure.
The recommended cables for using MODBUS communication;
-
CAT5 / CAT7 wires
-
J-Y (ST) Y 2x2x0,6
-
AWG22 (2x2 twisted pair)
