115/230 V selection on backplane inside Transceiver Unit
If the AC power system is 115 V, the Transceiver unit may be prepared for 115 V AC by re-connecting the
connectors J102, J103 as shown in gure 10.8.
This gure also shows position of fuses for 115/230 V AC and 24 V DC. These fuses are normal 5 x 20 mm
glass fuses.
AC supply: FS100, FS101 230 V 0.5 A slow blow. (Standard)
115 V 1 A slow blow. (Note: Not included)
DC supply: FS102 24 V 3.15 A slow blow. (Standard)
When the installation is complete, and power is connected to the Transceiver unit, the appropriate power
switch by the power terminals is switched on. Both 115/230 V AC and 24 V DC power may be connected
and switched on at the same time. If one of these supplies shuts down, changeover is automatic.
Rotate J503 180°
(wire entrance from
