Connect the L1-1, L2-1, and L3-1 cables from the QF02 switch respectively to ports A, B, and C
⚫
on the box-type transformer busbar 1 over a three-phase power switch.
⚫
Connect the L1-2, L2-2, and L3-2 cables from the QF04 switch respectively to ports A, B, and C
on the box-type transformer busbar 2 over a three-phase power switch.
⚫
Connect the functional earthing cable for the PID module to the ground bar in the box-type
transformer.
Ensure that the L1, L2, and L3 cables are connected in correct phase sequence.
⚫
⚫
Do not mix up the cable to the FE01 port with the cable to the FE02 port.
4. Bind the cable.
Connecting the Three-Phase AC Power Cable (a Knife Fuse Switch as
6.8
the Three-Phase Input Switch)
⚫
For the smart array controller that houses one PID module, connect the three-phase AC power
cable to the FU01 switch, and the functional earthing cable to the FE01 port on the functional
earthing bar.
⚫
For the smart array controller that houses two PID modules, connect the three-phase AC power
cable of the first route to the FU01 switch, and the corresponding functional earthing cable to
the FE01 port on the functional earthing bar. Connect the three-phase AC power cable of the
second route to the FU02 switch, and the corresponding functional earthing cable to the FE02
port on the functional earthing bar.

controller that houses two PID modules. For details about how to connect a three-phase AC
power cable for the smart array controller that houses one PID module, refer to the way of
connecting the three-phase AC power cable of the first route.
