2.8 Electrical supply
The line cord of the Modular
+
is connected to an internal terminal block. Directly connected to this
terminal are convenience receptacles and the unit itself. Line supply to the receptacles is available
with the line cord connected. Line supply for the unit is switched by the main switch at the right side of
the unit. The two pole switched power supply is protected by each one 5A circuit breaker. The
switched line supply is connected to the AC IN connector on power supply board AVM 2-1. Another
third pole of the main switch is connected via the terminal to the board AVM 2-1 (X5:5,6), enabling to
detect a main switch OFF position or missing line supply.
