MI 2792 PowerQ4 Plus
Introduction
8
allowed temperature for metal part of handle. In such environment it is advisable
not to touch the battery cover during or immediately after the charging.
Maximum voltage between any phase and neutral input is 1000 V
RMS
. Maximum
voltage between phases is 1730 V
RMS
.
Always short unused voltage inputs (L1, L2, L3, GND) with neutral (N) input to
prevent measurement errors and false event triggering due to noise coupling.
