Handling
There is a slight risk of damage to some of the devices in the RA226
in areas prone to high static build up. To eliminate this risk it is advisa-
ble to take a few simple precautions when handling the module.
1.The RA226 is supplied in a conductive
it from the bag until you are ready to install it in the rack frame.

5.Always return the module to its conductive plastic bag if it has to be
removed from the rack - especially if repacking unit for shipping.
Audio connections
Screened cable should be used for signal connections, the screens be-
ing connected to 0 volts at the edge connector only for the inputs and at
the jackfield only for the output.
A separate wire should join the Rack 0 volts to the main jackfield 0
volts.
Phono Rack
When the RA226 is plugged into a RA14RP phono type rack frame its
input and output will appear on the phono sockets behind the left hand
module slot. Before inserting the RA226 check the PCB on the rear of
the rack, earlier models have a track link between pins 5 and 6 on each
slot and pin 8s on each pair. These links must be broken before the
RA226 is installed.
If other connections to the RA226 are required then the racks rear con-
nector board can be suitably modified by your Rebis dealer or a quali-
fied engineer.
