Safety Note
To avoid injury and damage to persons and devices, it is absolutely necessary these instructions are carefully read and observed prior to assembly and commissioning. Necessary assembly, start-up, and maintenance work must be performed only by qualified, trained, and authorized personnel. Switch off the power line before wiring the actuator.
If the NovoCon® S network is supplied with two or more AC power boosters, caution must be observed when disconnecting one of the transformers from the high voltage power line. As the NovoCons are connected in a daisy chain, there may be high voltage on the primary side of the disconnected power supply. Disconnect always both the primary and secondary sides of the transformer.
Connect via safety isolating transformer. Galvanic separations shall be provided for segments crossing buildings.
Firmware update
We recommend validating the firmware version before installation. The latest firmware can be downloaded at www.novocon.com by selecting the tab: Support files.
