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 o 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,  t 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  tting 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.
