Even better than tape, I use those plastic thingamabobs that you get at a hardware store to plug into unused outlets to protect little kids from sticking something into the outlets. I then use a sharp knife to cut off any finger pulls that some have...just to make it a bit harder for an adult to stick something in as well.

A Large print "Telephone Equipment Only" P-Touch tape on all 4 sides as well, so there's no excuse for attaching to my equipment.

Wes've used the 700e and 1500e MinuteMan stuff for many (over ten) years. We have started to replace quite a few batteries the last 3 or 4 years now---but they have really, so far, done a nice job for us. We use and recommend them because:
1. They are inline. Not as good or expensive as online...but for our purposes...they do what they're supposed to.
2. They have trapezoidal sine waves. Not as good as a true sine wave, but much better than the square sine wave.

In other words, we feel we get the most bang for the buck. JMHO.

We have a habit of either putting them on a shelf that we make or on a shelf in a rack. We're going to have to break our habit soon, and install some of the newer rack mounted MinuteMans.

The rackmount UPS versions with a vertical rackmount bracket would be a good option for a "wall mount" UPS. Plus you'd also get options to some of the big boys if need be.

You'd reallly need to make sure you got one hell of an anchor for the big ones but it could work easy enough.

Yeah I really want to get away from the smaller weak batteries. But I guess anything large has to go on the ground, rack or shelf. But those of us who do smaller installs know that there isn't always a rack, not always room for a shelf and they are high up alot of the time.

I'll research the links you've given me and go with one of those or go with the apc750 which we've rigged to be securely wall-mounted.

I always put 350 to 750 va UPS on my installs for lightning protection (make sure to test the ground on the outlet) and tell the customer that the backup is a freebie to them. If they specify long run times, I charge them for the larger units. Also try using 2 4" D-rings at an angle as wall mounts for UPS w/o keyholes.

"just to make it a bit harder for an adult to stick something in as well."

Dave, do you know what a 1/2 horsepower hammerdrill plugged into an APC600 does? KILLS IT! But I guess you know that, huh. And the garbage it puts out is on the equipment side of the UPS, so even if the UPS takes the drain, the the garbage on the line will drive some KSU's 'around the bend', so to speak!

As an aside, most UPS manufacturers, as well as gel-cell type battery manufacturers, will tell you that if you get 3 years out of the batteries, ya done good. And 'exercising' the batteries really does help. Ideally, you run the UPS until the 'low battery' alarm comes on. And only one time has the power really failed right after a test.

Kinda neat. I'd probably use two of them (one on top and one on bottom) to not accidentally break the ears off the UPS. Looks like you'll need the square nuts to mount any unit to it though.

I wouldn't use them on the wall for sure. Telephone & Data ports should never be facing UP.

Come to think of it, I wouldn't even install them under a table or desk.

This equipment need to be properly installed on the wall. Tables & desks, like other furniture has a habit of getting moved....walls don't.

I thought we were talking about UPS equipment, not ports. My bad.

Found the Tripplite 350 and 780 in Office depot today and they have the holes for mounting on the wall. The APC's used to have them, but the new ones don't.

They are not true sign wave but for smaller systems they will do.
