We therefore strongly recommend installing a fuse directly at the battery
pole to prevent short-circuits.
3.6.1 Fuse in the PA15
The fuse is used solely to protect the PA15 against incorrect polarity and
excess current. The fuse must be replaced following a polarity reversal.
Only spare fuses of the same type may be used. This greatly increases
the safety of the system which also means that no dangerous operating
conditions occur even if the electronics fail.
3.6.2 Flammability
The PA15 comprises only non-flammable or self-extinguishing materials.
Even in unforeseeable error situations, no fires can be triggered if there
are no flammable materials in the immediate vicinity of the controller and
the remote switch has been installed on an incombustible base.
3.6.3 Fuse protection
A fuse protects the PA15 against single faults (e.g. load short-circuit,
battery reverse polarity, reverse polarity of the consumer equipment, etc.).

However, some double faults can result in the destruction of the remote
switch and the components connected to it (consumer equipment).
The PA15 TTS remote switch can be destroyed if, for example:
•
The battery has been connected with the reverse polarity on the load
output,
•
Regardless of the polarity, a battery connection lead is connected to the
battery input (A+ or A-) and the other battery lead is connected to the
load output (L+ or L-),
•
The battery connection has been connected to the switch inputs S,
