@Gwil would be the one to answer this.
However, the gland on the low-voltage end is a “standard” one for a round cable and does not anchor the flat cable that’s used for the d.c. power and the voltage samples. It would require a special bush (similar to this but noting the cable used is a lot flatter than 1 mm² TE) to provide a secure mechanical fixing, which I would expect to be prohibitively expensive.
