17.0 – Component Replacement
There are no user serviceable parts within the Zerio Plus panel. Only trained service engineers should
carry out the repairs listed below. Contact EDA Technical for further information.
Power Supply
Before removing the PSU remove the mains fuse from the terminal block and disconnect the battery.
The display should be off and no LEDs should be illuminated; inside or outside the panel. Unplug the
PSU connector on the EDA-Q2010 processor board (see diagram on page 10). Remove the live, earth
and neutral wires that run from the terminal block to the PSU. Undo the two M3 nuts that secure the
PSU to the panel chassis and remove the PSU. Fit the replacement PSU and secure with the two M3
nuts. Plug the connector back into the main processor board and reconnect the live, earth and neutral
wires to the terminal block. Insert the mains fuse into the terminal block and wait until the panel has
powered up before reconnecting the battery.
Display Board
Power down the panel by disconnecting the battery and removing the mains fuse from the terminal
block. Unplug the ribbon cable from the display board and remove the 5 screws holding it in place.
Once the new display board has been screwed into place, fit the ribbon cable and apply power to the
panel. Once the panel has powered up, reconnect the battery.
Processor Board
Power down the panel by disconnecting the battery and removing the mains fuse from the terminal
block. Unplug the ribbon cable connecting the display and processor boards. Unscrew the antenna
connector and unplug the PSU connector. Undo the terminal blocks used to connect any external
equipment from the panel relays, inputs, sounder circuits and RS485 terminals. The board is held in
place by 4 push pins. Press the tab into the middle of the pin and pull upward gently on the board to
release each corner, until the board can be removed from the chassis. The replacement board can
simply be pushed down onto the pins until each corner clicks into place. Reconnect all wiring before
fitting the mains fuse to the terminal block. Once the panel has powered up, reconnect the battery.
Fuses
This panel uses 5 x 250V 500mA and 1 x 250V 3.15A fuses.
