THA 275 PnP
Safety notes
Please observe the following safety notes
during the installation and connection.
- Disconnect the negative pole of the battery! Observe
the safety notes of the vehicle manufacturer.
- When you drill holes, ensure that you do not damage
any vehicle components.
- The cross section of the plus and minus cable may
not be less than 1.5 mm
- Use cable glands for holes with sharp edges.
- An incorrect installation can result in malfunctions
of the electronic vehicle systems or your car sound
system.
Installation and connection instructions
With respect to accident safety, the THA 275 PnP must
be secured in a professional way.
When selecting the installation location, select a dry
location that offers suffi cient air circulation for cooling
the amplifi er.
The installation surface must be suitable to accept the
accompanying screws and provide a fi rm support.
The amplifi er power cable must be fi tted with
a fuse no more than 30 cm from the battery (see
Fig. 2a) to protect the vehicle battery in case of a
short circuit between power amplifi er and battery.
The fuse of the amplifi er protects only the ampli-
fi er, not the vehicle battery.
Use loudspeakers with 2-4 Ω impedance (see table or
installation drawing). Observe the maximum power
handling capacity (music output). Do not connect loud-
speakers to earth, use only the referenced terminals.
Amplifi er THA 275 PnP
The amplifi er is particularly suited for connecting to
vehicle-specifi c plug-and-play adapters.
For the connection to car sound systems with ISO con-
nection, use only Blaupunkt PnP 25 or PnP 55 adapters
(part no. 7 607 622 010 or 7607 622 011).

Plus / minus connection
- We recommend a minimum cross section of 1.5 mm
The 12-V continuous positive cable must
be connected with the amplifi er + cable at the
vehicle adapter cable (7 607 622 ...)
(see Fig. 7).
- Route a commercially available positive cable to the
battery and connect it via fuse holder 30 cm from
the battery.
- Use cable glands for holes with sharp edges.
- Securely fasten commercially available minus cables to
a noise-free earth point (chassis screw, chassis metal)
(not to the minus pole of the battery).
- Scrap the contact surfaces of the earth point until
they are bright and grease with graphite grease.
Integrated fuses (Fuse)
The fuses integrated in the amplifi er protect the power
amplifi er and the entire electrical system in case of an
error. If a replacement fuse is used, never bridge fuses
or replace them with a type with higher current.
