Driller Posted October 10, 2012 Posted October 10, 2012 About to install this G2 plus a power RIO and want to make a really nice job of it. It's going in a server cupboard and so the cables aren't coming through the wall behind IYSWIM but from the side in conduit. What is best practice in this case? Is it accepted to slip the cables in behind the gap left by the spaces on the panel,I'm not sure this feels right somehow. Otherwise what's best practice when coming in from the side, the cutouts on the G2 and RIO never seem to be in the right place, although it could just be me of course. Here's a pic on the "bench" (or dining room table) of what I mean: I will of course strip the insulation back more on the install. Also, is it acceptable to use the 0V common to bridge over to the negative terminal on a PIR using EOL wiring. This is what it shows in the manual but up till now I've always run a separate wire from the Aux-.
Lwillis Posted October 10, 2012 Posted October 10, 2012 I usually take aux from the aux - not the 0v in the inputs Doesn't make any diff as they are all common anyway . Why are the cables side only could they not be routed into the top knock outs? If not where the rear entry points are , use those / may have to step the panel from the wall slightly or create a bigger space behind the panel Make sure the zones are easy to trace back to the cables - will help during fault finding
Driller Posted October 10, 2012 Author Posted October 10, 2012 Thanks for the quick reply L- gotta get this in this evening! I didn't want to open the top knockouts because of the possibility of dust ingress (ok I could be being a bit obsessive here) but saying that technically it could get in through the spaces on the back so...I may just do that All cables are pulled, tied and labelled. Thanks again!
james.wilson Posted October 10, 2012 Posted October 10, 2012 If your using conduit then use an elbow and relevant fittings into the top. Dust will get in from all angles as its not a sealed enclosure securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
norman Posted October 10, 2012 Posted October 10, 2012 4 core? wow! Nothing is foolproof to a sufficiently talented fool.
Lwillis Posted October 10, 2012 Posted October 10, 2012 4 core? wow! Didn't notice that first time around Can you still get 4 core ? I allways use 8 as standard
Driller Posted October 10, 2012 Author Posted October 10, 2012 Thanks for the tip James, I've got some of those I think. Er...what's wrong with 4 core is it a question of future proofing?
james.wilson Posted October 10, 2012 Posted October 10, 2012 You can never have too much wire. Often a false economy to use 4 core if using all 4. ie use a 6 or an 8 and have spare. We dont use 4 core usually use 6. Else we would have to stock even more cable types securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
antinode Posted October 10, 2012 Posted October 10, 2012 The four core is a little bit tight We always use 8 core, you never know when you'll need the spares. Future additons, damage, doubling up to reduce volt drop etc.The cabling is the hardest part of the install to replace afterwards so it's better to do that bit properly the first time IMO! As for cable entry, I'd recommend you use the top rectangular trunking knock outs. If you bring your trunking down from the ceiling it'll line up nicely. Don't worry about dust, you'll never stop it getting in there. In true Blue Peter style, here's one I made earlier Apologies for the butchered broadband filter but it was a case of getting the job done. Trade Member
