Fig. 1 Connection example
Please use the enclosed plastic (rubber) insert (if ordered, optional) to cover the
monitor terminals.
NOTE: If the START/STOP is connected as per Fig. 1, it is recommended that
terminals 6 and 7 be bypassed during programming. After the programming
is completed the bypass must be taken out. Make sure that the monitor
voltage range e.g. 3x380-500 VAC matches the connected motor/line
voltage, e.g. 3x 400 V.
