Notes
1.
CT circuits are shown connected to
1A tap - use alternative tap for 5A rated
CTs.
2.
CT and earth connections are typical
only.
3.
Optional expansion card, fitted only
on models AG2-311 and AG2-312.
4.
Optional expansion card, fitted only
on models AG2-321 and AG2-322.
5.
Rear RS485 port is an ordering
option. Connect wire link as shown to
include 120W terminating resistor in circuit.
