Safety • Exposed high voltage connections inside the unit • Both SRX-220 and SRX-220 require power cable connections that need to be permanently wired into the system • These need to be of the correct power rating and suitably protected
Safety • When working inside the projector, if it does not have to be switched on, disconnect the power connector from the wall and leave the connector were it can be seen • Do not leave unused supply cables with exposed ends unattended – tape them and secure them away.
