    1-10 ml of water (mostly liquid) is released with the gas. Attention! It is not the responsibility of Enapter S.r.l. to install and ensure the purge line is appropriately managed and maintained. Carefully refer to local rules and regulations, apply industrial safety standards where possible and assess the...

    In order to supply the EL2.1 with clean DI water for refilling, water must be present in the electrolyser water refilling pipe at a pressure between 0.5 bar and 4 bar. If the EL 2.1 does not detect the water's pressure, the system will not refill and will stop operation while it waits for water input pressure to appear.
  • Page 25 To facilitate faster refills, it is recommended to have at most 9 (nine) devices supplied by the same water line when connected only to Enapter's Water Tank Module. EL 2.1 - Owner’s Manual - Rev.02 – Mar 2021...

    13.77 mm (350 Ohm, 150 MHz) and can simply be slid over the cable. Connect the EL 2.1 as shown below to the socket labelled "Power". In the image below, brown is live, blue is neutral, and the yellow/green is the ground. Follow the relevant safety standards and ensure compliance with local and national regulations using the male connector in the correct orientation, as shown below..
  • Page 27 The EL 2.1 must be connected to ground to prevent users from contact with dangerous voltage and to allow the correct functioning of the device. The grounding system must comply with local and national regulations.
  • Page 28 The pins are, from top to bottom, S2, COM2, S1, COM1. This allows the EL to not only receive a dry contact signal but also to pass it on to the next Enapter device, allowing the installer/operator to daisy chain as many Enapter devices as wanted to a common safety signal.

  • Page 29: Electrolyser Monitoring Tools

    The EL 2.1 comes with a preinstalled UCM (Universal Communication Module), which provides the immediate ability to monitor and manage the device. It does this by sending data to the Enapter Cloud, which stores it in a time-series database and provides real-time or on-demand visualisation of collected data on customisable dashboards.
