breaker: mount the line breaker or load switch with fuse.
If there is a need to install the earth leakage circuit
breaker: mount the earth leakage circuit breaker
compatible with appliances for grounding, over load
and short circuit protection.
2 . The remote controller wiring (P1 and P2) and
transmission wiring (F1 and F2) is of no polarity.
<Precautions to power wiring connection>
• Never connect two wires of different size to the same power
supply terminal. (Loose electric wire connection may cause
abnormal heating.)
• When connecting to the terminal blocks, use the circular
terminal with insulation sleeve. If not available, connect
the wires of the same size to the sides respectively as
shown in the figure.
