How to install Vertiv Liebert TDU

Installing the Vertiv Liebert TDU should be performed by qualified personnel following all applicable electrical codes and safety practices. The steps below provide a high-level guide to typical installation scenarios and are not a substitute for the official installation manual.

  • Power down all connected equipment and isolate the installation area to prevent accidental energization during wiring. Verify that you have the correct input supply (208VAC or 240VAC) and the appropriate output connections for 120VAC loads.
  • Mount the Liebert TDU in a suitable enclosure or location with adequate ventilation. Ensure there is sufficient clearance around the unit for heat dissipation and safe cable routing. Avoid placing the transformer in areas with excessive moisture, dust, or restricted airflow.
  • Connect the input conductors from the facility power source to the TDU's input terminals as specified in the installation manual. Ensure proper identification of line, neutral, and ground connections, and confirm that all connections are secure and tightened to the recommended torque specifications.
  • Connect the output conductors from the TDU to the protected loads that require 120VAC. Maintain correct polarity and grounding, and avoid overloading the transformer beyond its 3440VA/3440W rating. Use appropriately rated cables and protection devices as required by code.
  • Perform a controlled power-up sequence: verify all interlocks, check for proper voltage regulation at the output, and monitor for abnormal temperatures or audible indicators. Confirm that connected equipment starts normally and that protection devices (e.g., circuit breakers, fuses) remain in acceptable operating ranges. Document configuration details and test results for ongoing maintenance.

Wow!!!
Size: 80 ea
XyliMelts were recommended by my new dental hygienist who said she was told about them at a dental conference by a well known hygienist "guru". I ordered them at around four in the morning because I was up as usual because if my chronic pain syndrome and the dry mouth caused by my pain pills. I got them quickly via Amazon and have not been up again this time of night due to the dry mouth. Now I'm up due to the pain but can fall asleep quickly because of the XyliMelts, they work great! I only use one at a time and it lasts around four hours and I put in another one and go right back to sleep. It's so easy to push the little tab out of the cellophane and just hold it on my gum for ten seconds and voila! No more dry mouth. I used to wake up with my mouth so dry there was no saliva at all in my mouth and parched was an understatement, my mouth felt like sandpaper! Now it's always nice and moist and the taste is extremely pleasant (I didn't get the mint). I had to have two teeth extracted four days before Christmas and my dentist said it was due to the dry mouth and that he sees patterns like this in patients with dry mouth and I'd probably lose more teeth unless I came in for cleanings and check ups three times a year instead of two and we kept a really close eye on my teeth. I'd been using Biotene gel but it wasn't keeping my mouth moist long enough. I'm extremely happy with XyliMelt! I'm also 100% sure I won't be losing any more teeth due to my night time dry mouth because it's a thing of the past! Thanks to amazon prime shipping I got my XyliMelts very quickly, and my nighttime dry mouth is a thing of the past! I know they don't claim to stop cavities but without the dry mouth and my new commitment to see my dentist three times a year and to always always brush my teeth before I fall asleep (no more Rolos in bed after I've done my final teeth brushing), I'm confident my dentist won't see a tooth loss pattern in my mouth.

Xylimelts work...very very well..finally moisture to my mouth for longer than anything i have tried
Size: 80 ea
i have xerostomia...this is a dry mouth due to radiation treatments...I have minimum saliva. I must sip water or a liquid with every bite of food. When i talk my mouth quickly dries and makes it difficult to speak......I have tried many....many different sprays, gels, etc. etc. Along came Xylimelts and it has been the best thing for me to date. It does add some moisture to my mouth and the great part is that it lasts for a very long time. I use the mint free only because my dry mouth is more sensitive to certain tastes. I once used Biotene and now i stay away from all of their products.....Biotene was around a while and marketed their product and had become very popular....Glaxo Smith Kline ( the big drug company that only cares about their profits over our health) purchased Biotene and had altered the product for the worse and they have done this with other products. They actually removed beneficial ingredients and replaced them with poor ingredients....Here is just one example: Xylitol was in one of their products ( Biotene toothpaste) when they purchased the company from Biotene. Xylitol has beneficial qualities and they replaced it with the Cancer in Laboratory rats ingredient called Sacharin... They have removed other ingredients as well...I stay away from any product from Glaxo Smith Kline. I have my own personal boycott and that means I no longer buy their Tums as well... Yes...They played their games with Tums also.....so i just do not buy their products. Xylimelts does work for me...very very well. It adheres to the gums above my teeth and it just stays there adds moisture to my mouth. Obviously i recommend this product

I'd rate them 5 stars if only I'd had them to use over the last two decades!
Size: 80 ea
A couple of years ago my dentist and hygienist told me about Xylimelts, which I promptly ordered and appreciated as soon as I used them. After suffering teeth problems due to meds for years, it's too late for me to save my uppers -- dry mouth had decayed my teeth, even with plenty of hydration, good dental hygiene and wonderful dental care (when I didn't put it off a few times, sigh...), and I’m about to get dentures :( . I started out putting two in my mouth at night, but that seemed to be a bit much -- they'd cause me to drool and stain my pillow (washed right out!) Mostly out of concern for the cost of Xylimelts, I began putting only one in my mouth at bedtime. This has worked well for the most part, though some nights I still wake up with a dry mouth, and sometimes put in another one. This could be due to allergies though, my nose is often stuffy as I sleep. However, two would probably prevent this from happening. I tried the non-mint kind first, then accidentally ordered the mint kind once, but I prefer the non-mint flavor. It’s got no real taste, and that suits me fine. By the way, it does take 10 seconds to adhere them, but if you are not comfortable with that spot, you can move them to a better one without them losing their “stick” to the outside of your teeth or gums.
