Note:
In 220-240 V panels, the 4010ES requires a true transformer output of 220-240 V. Do not connect two out of phase "hot" wires to create
the desired voltage.
When connecting the AC power wire to the AC block, it needs to pass through a ferrite bead to reduce radiated emissions. Route the black
and white AC power wires to the supplied ferrite bead. Loop the wires twice through the bead and secure with two cable ties as shown in
Figure 40. The cable ties are supplied in the ship group that comes with the panel.
