INSTALLATION
4.1.
Mains Powered Operation
Please refer to the hardware installation guide, which was included in the product package. It provides
detailed installation instructions.
4.2.
Low-Voltage Operation (Maintenance and Early System Integration Stages only)
Instead of applying dangerous mains voltage to the load switch S2, you may connect a low-voltage DC
source (e.g. 12V=, 24V=, 48V=) to the supply lines of S2. Its built-in universal power supply is able to
operate from both kinds of supplies, direct and alternating current. This can be useful during
maintenance or early stages of system integration. In this mode, the ZigBee interface is operational and
you can run OTA firmware upgrades, for example. However, the inputs and outputs are non-operational
and attempting to switch the output can result in a reboot, because the device detects a malfunction.
For DC operation (laboratory use), connect the DC ground (0V, “minus”, negative) of your power
supply to the phase input of S2 (marked “L”, brown) and the DC supply voltage (12…48VDC, “plus”,
positive) to the neutral input of S2 (marked “N”, blue). Once powered, you should observe the normal
device start-up behaviour (the green LED will flash a few times).
If you are not using a safe low-voltage power-supply, utilizing the services of a professional
installer/electrician is imperative.
