Installation tricky switch missing

Have the device installed until about a month ago, so I can not comment on the effectiveness, but so far but no Marder has slammed shut. If connects between ground and a contact plate by hand, you get an unpleasant electrical shock. In addition, a LED will flash on the device itself and it emitted ultrasonic chirps that should scare the raccoon.

However, the installation is not quite trivial: you need access to mass, permanent plus and it is recommended a ignition plus, with which the unit is turned off while driving (I have omitted the ignition plus and the appropriate cable connected firmly to the ground, making it even is active during the journey). In addition, the installation of a switch is recommended, which allows you to disable the device. So a switch could have been in my opinion even able to accommodate the device itself (who may nevertheless can still turn in a second dashboard accommodate).

The manual is relatively detailed, but gives no exact information on where exactly you should mount the high-voltage contact plates. The high-voltage contact plates can be very good fit with cable ties in the engine compartment, but should ensure that they have no contact with earthed parts (also plastic hoses in the car are sometimes low conductive). The screws with which the contact plates are mounted on its holder (just hard to reach places in the engine compartment) quite heavy zuzudrehen.

Although I am sent by hand, the installation has cost me several hours, whatever it was sure that I was very careful and had to be extended a few cables as they have fallen somewhat short of the house. A skilled KFZ'ler makes sure faster.

Slightly longer cables for the power supply and a built-in switch on the device itself and it would be a strong buy recommendation. There are two star deduction.
