ocedure
Outline of electrical equipment box (Typical)
Connection of remote control input
To execute remote control, connect the cable according to the procedure below.
Local procurement items
Remove the short-circuit bar (between terminals [10] and [11]) on the terminal block in
the electrical equipment box.
(For the crimp tool, use the specified tool.)
Connect the cable specified in above between terminals [10] and [11].
∗
12 VDC is applied across these terminals (Terminal [10]: negative polarity, [11]: positive polarity).
Component
Single-pole, single-throw remote control switch, or “a” contact that enables operation command output
Note) Select a switch whose minimum allowable load is 12 VDC and 5 mA.
