CAUTION
Danger of electric shocks!
– Before working on possible live components,
ensure the unit is disconnected from the power
supply.
– The RGA 100 must have an external 16 A fuse.
– It must be possible to isolate the system from the
power supply. The RGA 100 must be equipped
with a mains cable or a plug featuring a contact
gap according to the specifications for Over-
voltage 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 instal-
lation regulations.
