I had to fix a new plastic box in my observatory & used a drill to make the appropriate fixing holes.

 

I moved all the essential cables sideways so I would not drill through anything other than the wood to mount the screws.

 

However, as always, there was a cable I did not see- and guess what "Murphy" moved the cable so it was exactly under the wood I was drilling through and then entropy stuck his nose in ensuring that the cable was aligned almost exactly with the drill bit- the chances of this happening by chance must be like winning the lottery- it mostly is not going to happen. I drilled straight through the 48V power cable for the Paramount MX+- but as always when doing this work there was no power connected to the accessories.

 

I proudly finished the job- turned everything back on & no Paramount initialised. I thought the PSU had died in the interim as a meter showed no 48 volts. So I rummaged around & removed the PSU & examined the cable- with the beautiful hole drilled straight through the cable. I was fortunate that there was no power connected & I had an Anderson power-pole kit on hand to repair the broken section of cable. A picture of the damage is below.

Be careful guys with your equipment......Murphy & entropy are waiting to get you!

 

 

Stay Safe!

 

Best wishes

Lucky for you, Murphy was slowly losing his grip...or you would have shorted the not too inexpensive 48v PSU, because you had not turned off the power.

I suspect that if power was connected it would have taken out the MKS5000 board & it was lucky when powered back on that the drill had effectively severed the power- a short circuit would have been a disaster !

Anderson power-pole connectors are wonderful for fixing this type of issue- I'm really glad that I learnt to use them.

They should be in everyone's kit for just that reason - sooner or later you're going to but a cable and they are so much easier to use than splicing things together.
