Step 5. The wires of the main power must pass the bonding clamp.
Step 6. Wires should be connected firmly to the connection terminals A, B, C and N.
Step 7. Phase sequences must be consistent when the wires of the main power.
Step 8. The main power should be located out of easy reach of non-professional maintenance personnel, to avoid mal-operation and
improve safety.
Step 9. Connection of control wires of water flow switches: the wire leads (prepared by the user) of water flow switches are connected
to the connection terminals W1 and W2 of the main unit.
Step 10. Connection of control wires of auxiliary electric heaters: the control wires of AC contactor of the auxiliary electric heater must
pass the connection terminals H1 and H2 of the main unit, as shown in
Fig. 5-2
.
Step 11. Connection of control wires of pump: the control wires of AC contactor of pump must pass the connection terminals p1 and P2
of the main unit, as shown in
Fig. 5-3
.
Step 12. The connection way of the wire controller connects with every signal wires from package units: signal wires P, Q, E are
connected in the same way of main wires connection method and accordingly connect to the terminals P, Q, E in the wire controller.
