2.3 Installation
2.3.1 Controller
The ELFAMATIC µC 3000 must be fitted in the bottom row of a distribution board, whereby a gap
of one SI circuit-breaker width must be provided at the sides.
Shock protection to safety class II is provided if the ELFAMATIC µC 3000 is installed in
●
a small distribution board to DIN or
●
a distribution board to DIN
The ELFAMATIC µC 3000 consists of a base with terminals
for rail mounting as well as the plug-in housing with the
