3 Installation

3.1 Removing/Replacing the Electronic Assembly - iRIS 220

The electronic assembly is retained in the case by two end plates and held in place by the two connectors (I/O and RS232). Follow this procedure to gain access to the printed circuit board (PCB) to change the SIM card on GSM models (see Section 3.3) or to change the digital input links (see Section 3.4.5).

To Remove: Undo the two mounting screws at the antenna end of the case (if fitted). Unplug the I/O connector. Unscrew the two retaining screws on the RS232 connector and remove the connector extension. The PCB can then be carefully removed by sliding it out of the outer case.

NOTE: Once the I/O connector and RS232 connector extension have been removed, the PCB is no longer retained. Take care to prevent the PCB falling out of the case.

To Replace: Reverse the removal procedure to reassemble the unit.

3.2 Opening / Closing the Housing - iRIS 320 / iRIS 320V

The front of the iRIS 320 enclosure is secured by three M5 machine screws with Allen Key® heads.

NOTE: The two left-hand screws act as links to the hinges and should not be fully unscrewed.

To Open: Undo the right-hand screw completely and put in a safe place. Undo the two left-hand screws until their heads are just fully clear of the front’s face. The front should then be able to be swung open to the left, to a maximum angle of 90°.

To Close: Check that the green gasket is fully installed in its retaining groove. Gently swing the front closed to the right, pulling it slightly forwards if it appears to catch, before finally pressing it fully home and then tightening the three M5 screws securely to maintain the IP65 rating of the enclosure.

Fit a new tamper-proof wire seal to the right-hand screw if required for security purposes. Slight adjustment of the screw may be required to align the holes in the screw and enclosure to enable the seal’s wire to be passed through.

3.3 Removing / fitting the SIM card (GSM models only)

Important! Ensure the iRIS is depowered before attempting to remove or fit the SIM card.

Using a fingernail or small screwdriver inserted into one of the two oval holes on the sliding holder, gently lower the slide downwards to unlock it. The slide can now be swung forwards from its top end to enable the SIM card to be inserted or removed. Reverse the procedure to close and lock the card into place.

Caution: Exercise care when inserting or removing the SIM card, as the carrier is fragile.
