It has recently come to our attention that some transformers shipped with the IQ Hardwire Power (PG9WLSHW8 and PG9HRDW8) may have the polarity reversed (positive = negative & negative = positive).
This impacts transformers with a date code of 2448 (48 week of 2024) the date code can be located on the bottom right of the label.
Please note if you do not have a meter to read the polarity, connect the power to the IQ Hardwire PowerG with no battery connected, if the unit powers up then the polarity is correct.
If impacted, you may use the reversed polarity of the transformer by reversing your wire connections
