6.2.1 Names and Applications of Main Circuit Terminal Block Signals

The following table shows the details for each terminal block signal.
Name Signal name
L1, L2, L3 Main circuit power supply
Control circuit power sup-
L11, L21
ply
MC1, MC2 Contactor control
Protective grounding
(PE)
CAUTION
(1) Always use one AC reactor per power supply unit. Failure to observe this could lead to unit damage.
(2) If a circuit protector is shared by several power supply units, the circuit protector may not activate when a short-
circuit fault occurs in a small capacity unit. This is dangerous, so never share the circuit protector.
(3) Be sure to use the circuit protector of the appropriate capacity for each power supply unit.
