Because the GFCI relies on the detection of current leakage from AC line to ground, it is occasionally
possible to false trip the GFCI if additional filters with unacceptable levels of current leakage to ground
are used in conjunction with the Reference unit. As these designs can actually create as much noise as
they attempt to reduce, we recommended they
not
be used. If you experience a false tripping of the
GFCI, just press the reset tab in the center of the GFCI. If the RI-1210 or RI-1220’s GFCI protection cir-
cuit is activated, the blue AC output indicator will not light, and there will be no power delivered to your
systems components. The GFCI is located on the rear panel, and its AC outlets make up two of the six
Analog AC outlets.
Surge Protection
The RI-1210 and RI-1220 are capable of suppressing virtually any instantaneous voltage surge caused
by lightning or commercial power. However, the protection device may be damaged if the over-voltage
surge or spike is sustained. The same is true if the device is made to absorb a
direct lightning hit
. The
device in conjunction with the magnetic circuit breaker will protect your valued equipment, but in extreme
circumstances, the protection device may be damaged. If so, the circuit breaker/power switch will not
stay in the “on” position. If this happens, your Reference unit must be serviced.
Safety Information
Please read and observe all of the safety and operating instructions before the RI-1210 or RI-1220 is op-
erated. Retain these instructions for future reference.
•
Do not disassemble or modify in any way. No user serviceable parts inside.
•
Keep away from moisture and extreme humidity.
•
Do not allow liquids or foreign objects to enter the unit.
•
Lighting equipment may not be connected to the RI-1210 or RI-1220, as light sockets are not de-
signed for Balanced Power. In accordance with the N.E.C.’s standards for use of Balanced
Power, we recommend that the Reference unit be limited to use with audio, video and computer
equipment.
The RI-1210 and RI-1220 should be serviced by qualified service personnel when:
•
The power supply AC cord has been frayed or cut.
•
Objects have fallen on or liquid has spilled into the unit.
•
The unit has been exposed to rain or extreme moisture.
•
The unit will not operate, or function normally, showing a marked change in performance.
•
The unit has been dropped, or its enclosure has been damaged.
•
The power indicator will not light, even after resetting the GFCI.
The RI-1210 and RI-1220 require that the safety ground be utilized from the source AC power to the in-
put of the Reference unit. This ground connection is necessary for optimum performance. Any attempt
to operate the RI-1210 or RI-1220 without the incoming safety ground is considered improper operation
and will invalidate the warranty.
