Power Linking of Multiple Devices
This device supports power linking. Power can be relayed to another device via the power Out (12)
connector. Note that the input and the output connectors have different designs: one type cannot be
connected to the other.
Power linking of multiple devices must be carried out only by instructed or skilled persons.
WARNING
Incorrect power linking may lead to overload of the electrical circuit and result in serious
injuries and damage of property.
To prevent overload of the electrical circuit, when power linking multiple devices:
●
Use cables with sufficient current-carrying capacity. The power cable supplied with the device is
suitable for power linking of multiple devices.
●
Make sure that the total current draw of the device and all connected devices does not exceed the
rated capacity of the power cables and the circuit breaker.
●
Do not link more devices on one power link than the maximum recommended number.
Maximum recommended number of devices:
●
at 100–120 V: 5 devices Alpha Series A3.9i
●
at 200–240 V: 10 devices Alpha Series A3.9i
To connect multiple devices on one power link, follow the steps below:
Make sure that the devices are not connected to the power supply.
Connect the Power Out (12) of the first device to the Power In (14) of the next device with the
supplied power cable.
Repeat step 2 to connect the rest of the devices in the setup, as shown in Fig. 62.
Connect the first device on each row, respectively the first device on one power link, to the power
supply.
Note:
Make sure that maximum recommended number of devices on one power link is not exceeded.
