Victron BP220 terminals not identified

Hi Team, I installed a BP220 in concert with a V2 BMS and a set of 2 x 25V/200amp smart batteries. the BMS can disconnect the BP220 when if the battery voltage is to low by connecting from "load disconnect" on the BMS to the H terminal on the BP220. the H and L terminals on the BP220 I have installed are not labelled. all of the photos of BP220s that I have found have the connection terminals mounted at 90 degrees to mine and even the Alarm, GRD and PROG terminals are reversed orientation. I haven't ben able to find any manuals showing the terminal markings on the BP220 I have. which terminal should be the H terminal please? a picture or manual showing thebp220-pic.jpg same BP220 I have would be great please. Thank you

Wasn't there a physical manual included in the box?

I think you are looking at the wrong online pictures/manuals.
The Smart BatteryProtect has the terminals labeled with L & H and the they are rotated 90°.

But it seems you have the normal non-smart BatteryProtect.
