Option setting for use of many watthour meters ("Grouping of electric power port" to be specified) 18 units (Max.) of watt hour meter for one iPU (the
1st one) and 19 units (Max.) of that for each iPU among several iPUs (the 2nd or more one) can be connected. Therefore, when 4 units of iPU are
used, 75 units (Max.) of watthour meter can be connected. (It is not recommended to install many watthour meters.)
In this case, it is also allowed to specify the option of "Grouping of electric power port".
Normally, it is not necessary to specify it. The system connection example is as shown below. For both Pattern 1 and Pattern 2, the calculation method,
if specified, is the same.
• Pattern 1: Three watthour meters to be connected to one iPU:
