(1) Remove the terminal block cover on the lower right side of the unit's
rear panel.
(2) Connect the units that need to be backed up. Two types of connections
can be made.
1) To turn ON/OFF at the same timing as that of output receptacle B:
L1B terminal: Connect the line
L2B terminal: Connect the neutral line
2) To turn ON/OFF at the same timing as that of output receptacle C:
L1C terminal: Connect the line
L2C terminal: Connect the neutral line
Run the wires to be connected through the hole in the included terminal block cover (with cable
clamp and cable guard tube). (See Figure 1.)
If you have trouble running the wire through the hole, loosen the cable clamp dial by turning it
