Evening,

 

Just about to have an Indra Smart Pro charger fitted to a very thick brick pillar on the garage. I want the install as neat as possible so to have the cables enter from the rear. Plan is to pre drill the holes so it's as easy as possible for the installer.

 

I've contacted the installer who reckons the hole centres are at 3.5". Tbh I have a feeling that's wrong from scaling up a plan view image on screen. Posting up here on the off chance someone here might have one they can measure for me. 

 

Many thanks in advance

Hi ​@Onoff ,

I’ll see if I can get one of my contacts at Indra to take a look at this thread. I can’t make any promises, but if they do give any thoughts, I’ll let you know.

Bear with me!

Morning ​@Onoff and a warm welcome to the community! I’ve added the EV badge to your Forum profile.

 

I’m wondering whether one of our Indra Smart Pro owners might be able to help here?

 

@Bobbych ​@MikeyB ​@tony1tf ​@BobTom ​@Pmac295 any help would be much appreciated 😁.

I have the Indra and if anyone else does there is no way to measure this as it is installed on the wall. So no way to measure the hole spacing etc 

 

giving the cable needs to be connected to the lower section on the charger have the feed there means it would need to be routed down to the bottom and looped  back into to connection. Probably fine if the one you have is untethered like mine. That would allows some space for the cable. If yours is tethered like that picture you have included then there is not a lot is space for the main cable. It is best to have the main cable routed through the bottom of the unit in my opinion

Mine is tethered and looks like this underneath. They are quite large cables. Agree with ​@Bobbych that you can’t access the fixing holes once installed.

To make the install easier stick to the lower ports. You can hide the cables using something else

 

whilst I am happy to help here I am on the verge of moving to octopus as I cannot allow OVO to charge me 14p per kWh.

Indra commented they can’t help with this answer I’m afraid - they've asked me to mention that their stance is that you’d need to leave this to your installer.

Thanks all. I'm quite sure the installers default will be keen to have the cable come in from the bottom but tbh that's just the quickest and easiest route for them without any thought as to the aesthetics. It also makes it awkward for future external wall insulation.

 

Their own literature shows the rear knockouts can be used. I'm quite happy to pre drill the wall, a brick pillar in fact and some 400mm thick. I'll make a better job tbh than any installer.

I suggest hard wiring the Ethernet too too many issues with either WiFi or 4g.

Yes I have duct grade Cat 6 to go all the way from the house consumer unit to the EV charger. I'm doing separate SWA & Cat 6.

Looking at the photo posted above.
Here’s an idea to overcome the issue of pre-drilling precisely aligned holes for rear cable entry.

Remove about half a bricks width to full depth and (depending on the construction of your pillar) drill your cable holes through the bottom of the resulting recess.

That should give plenty of leeway for the unit to be positioned to cover that recess with the cables going through the rear knock-outs.
Exact alignment is not requred because the full brick depth of the recess allows for offset as the cables bridge across it.

If you should happen to make the recess slightly too wide then any gap can be filled/covered after installation.
