3.3 Install the IQ-PIP-USP3/CN Into
the
Amplifier
Carefully ground yourself to the chassis of
the amplifier
before installing the IQ-PIP-USP3/
CN. It is a good idea to maintain ground contact
between yourself and the amplifier while inserting
the module into the amplifier.
Connect the PIP module to the amplifier.
1. Turn the PIP module upside down so the ribbon
cable connectors located along the back edge on
the underside of the module can be clearly seen
(See Figure 3.1)
2. Attach the ribbon cables from the amplifier to the
ribbon-cable connectors. The 20-pin cable (A)
should connect to the connector closest to the
corner and the 18 pin cable (B) should connect
to the other connector.
Important: Be careful when attaching
the ribbon cable to the connector.
Applying pressure to an improperly
seated connector could cause the keying tabs,
which ensure proper pin alignment, to break.
Connecting the ribbon cables with improper pin
alignment will likely result in damage to the PIP
module.
3. Set amplifier sensitivity.
Mount the PIP module in the amplifier.
1. With both cables firmly attached, turn the IQ-
PIP-USP3/CN back to an upright position. Verify
that the cables run untwisted between the ampli-
fier and the PIP module.
2. Insert the PIP module into the amplifier while
taking care not to crimp, pinch or stretch the rib-
bon cables.
3. Fasten the PIP module to the amplifier rear panel
with the two supplied mounting screws. Be sure
to use the supplied star washers for a good
ground connection.
