7.5 Installing AC Input Power Cables

7.5.1 Installing Cables for a 110 V AC Dual-Live Wire System (L1,
L2, N)
Procedure
Step 1 Route the 110 V AC power cables into the cabinet through the holes at the left bottom of the
cabinet.
Step 2 Route live wires L1 and L2 through the current transformer.
Step 3 Secure the AC input power cables to corresponding AC input circuit breakers and terminal, as
shown in


If an AC meter and a current transformer are configured, route the AC input power cables through
the current transformer first and then connect them to the AC input circuit breaker. If a 110 V AC
dual-live wire (L1 and L2) input power grid is met in this case, after installing the AC input power
cables, you need to change the cable connection for the AC meter.

Note the direction of the current transformer.
indicates where the current flows out.

If neither an AC meter nor a current transformer is configured, the AC input power cables can
directly connect to the AC input circuit breaker.
 If a 110 V AC dual-live wire (L1 and L2) input power grid and an AC output are both met, you need
to change the cable connection for the maintenance socket.
 This section elaborates the case in which an AC meter, a current transformer and a maintenance
socket are configured.
Route L1 through hole A on the current transformer and L2 through hole B.
