The mains voltage selector switch provides a simple external adjust-
ment to allow operation on all international AC power standards.
Newer units are supplied with 115/230V selector switches. The allow-
able ranges for the supply voltage are:
90VAC up to 132VAC on the 120V or 115V position and
190VAC up to 264VAC on the 240V or 230V position.
Outside these voltages the unit will not work satisfactorily, if at all.
Voltages in excess of the maximum will probably cause damage.
Voltages below the minimum will cause the power supplies to drop out
of regulation, degrading the performance of the system. The battery
pack in the remote will preserve all data in the event of a power failure.
The Green and Yellow wire of the mains cord must always be con-
nected to an installation Safety Earth or Ground. It is essential for per-
sonal safety as well as the correct operation of the system, and is inter-
nally connected to all exposed metal surfaces. Any rack framework into
which this unit may be mounted is assumed to be connected to the
same grounding circuit.
The incoming mains power is fused within the FPC-900i by the fuse
holder mounted on the rear panel. Should it be necessary, the fuse must
be replaced by one of the same size and current rating.
20mm T200mA for the 240V o r 230V setting
20mm T315mA for the 120V or 115V setting
It is most important for continued safety that this specification is strictly
adhered to. Spare fuses of the correct rating are supplied with the unit
from new.
It is unlikely that the AC fuse will fail during normal use and caution
should be exercised if it does. The most likely reason at first power up is
the incorrect setting of the mains voltage switch on the side panel.
Another reason may be the connection of the unit across two lines of a
three phase supply. In both of these cases the internal transient suppres-
sors may have been damaged and will continue to blow replacement
fuses, even if the supply is now correct. The suppressors will have
protected the FPC-900i from damage and need replacing before the
interface can be used again.
Refer to section 19.1 for the replacement
procedure.
