Figure 5.3.2-1 Connections of the master unit (example).
5.3.3. Wiring secondary circuits of current
transformers
Connect the secondary circuits of the current transformers to
the following screw terminals at the rear of the master unit
(see Figure 5.3.3-1 ):
X1-1, X1-2 (L1)
X1-3, X1-4 (L2) (E/F (220R))
X1-5, X1-6 (L3)
(see Figure 5.3.7-2 for E/F schemes using VAMP 220R)
The arc protection system can also be two-phase or single-
phase connected. But for obtaining optimal operating speed, a
three-phase connection is recommended.
NOTE!
The specified 7 ms operating time can be guaranteed only if
three-phase current measurement or two-phase current + E/F
(220R) is used.
