The Nittan EV1-PSU is the replacement power supply cage for the Nittan evolution 1 single-loop touch screen fire alarm control panel (F12-83101). In the evolution 1 the switch-mode power supply sits in its own cage, which carries the mains Live, Earth and Neutral connections.
Use it to replace a faulty or damaged power supply cage on an existing evolution 1 panel. Nittan's installation manual says the mains earth must be connected to the PSU earth terminal and the clear plastic cover refitted over the mains terminals after connection.
