Power supply is indoor mounted. It requires sealing case for outdoor installation. The source is connected to the 220V ~ 50Hz through distribution block. The output voltage connection polarity to the load is indicated on the case of the device. When power is connected the LED on the case will be active.
WARNING!
To increase the lifetime of the power source you must observe the temperature profile in the technical specifications. Above the upper temperature limit burst protection may turn on. This turns off the LED and turns off the output voltage. When you restore the normal temperature mode the power source will resume functioning automatically.
