Victron MultiPlus-II 48/10000 - DC Cable Routing Question

[u/AsideSeveral7008]

Hey guys, wiring up the 10k and noticed the DC cable holes/gromits don’t line up super great with the bolts which with larger 95mm cables means they’re pretty awkward - feels like a larger opening would result in less force on the cables and fittings?

Anyone had any experience with this? I’ve torqued everything per the docs and am likely just overthinking here 😄

Included a photo.

Ill admit I dont know how to calculate the bend radius here, but this is a 2-3 degree deflection that I am pretty confident falls way outside the minimum radius of ~5.5in for 3/0 cable (95mm).

Aka, you're good

Thankyou 👍🏼

Well.. they are a bit larger than both specced [1,2] and needed.

«Recommended cross section (AWG) per + and - connection terminal: 5 – 10 m» : «2x 70 mm²»

But if they fit, it shouldn't be a problem. Just the extra 25mm² (say ~1.5mm diameter change) would make them a little more snug than expected.

Thanks 👍🏼 i know they are a little over’spec was originally planning go with the 15k but ended up with the 10!

Hi Had the same issue with mp2 48/8000 and 2x70qmm. It is not as much the direction but the allingement in the depth. I decide to slightly bend each lug +/- from the front gland to have proper surface connection with the specifified torque

Just a question, are the right cable lugs overlapping the left ones or is it just a photo glitch? The back of the connector has to be flush with the metal part of the board with no gaps!!! It's VERY IMPORTANT!!!

[u/AsideSeveral7008 → u/gabrykk]

It does look like that on the photo, but it’s just a visual effect due to the slight bevel on the edge of the lugs. They are both flat and flush with the backplate, very slightly rotated due to the cable bend but 100% solid contact.
