CAUTION

Danger of electric shocks!

– Before working on possible live components,

ensure the unit is disconnected from the power
supply.

– The TR 75 must have an external 10 A fuse.
– It must be possible to isolate the system from the

power supply. The TR must be equipped with
a mains cable or a plug featuring a contact gap
according to the specifications for Overvoltage
Category III for full isolation at each pin. If this is
not the case, the permanently wired electrical
installation must include an isolating switch of
this type pursuant to the local installation regula-
tions.
