APC Back-UPS ES BE700G-GR general questions

[Anonymous user]

Hello.

Just got the ups, plugged in the battery and it's been charging ( as soon as i plugged it in the led went green, i did not press the on button ) for about 14 hours now.

I want to know some things :

1 - The 4 surge protection outlets are independent right ? I can plug in stuff that uses more than the 400w the battery offers ( on the 4 outlets that have battery backup ) ?

1a - I can plug in things that use a motor in these outlets right ( fridge, washing machine ) ?

2 - On the 4 battery backup outlets i can't plug in stuff that uses a motor ( fridge, washing machine ) because the ups does not have pure sine wave output, right ?

3 - I'm confused about the rj45 ports usage. Am i supposed to plug in the internet cable ( the comes from outside ) in the  "from wall jack" ( middle port ) port and the cable that will go to the pc network card in the "dataline output to DSL modem/phone/network (10/100 base-t)" ( the port closest to the ground ) right ?

4 - I'm confused about the "Telephone Cable OR Network Cable should be connected to Surge Protection ports. Do not connect the UPS surge protection ports to both Telephone and Network System cables at the same time."

How can i connect the phone and network at the same time, there is only 1 port ( the one in the middle ) ?

Cheers.

Hi Turdorache,

Yes you can say the surge only outlets are independent. They will always pass power as long as the unit is plugged into the wall. However, I would not plug devices with motors into these outlets. This is because deivces with motors can distort the input power and thus can cause the back-ups to transfer on and off battery. See the link below about using laser printers with back-ups, the same characteristics would apply to a washing machine/fridge.

2)Yes the Ups does not have a sine wave output but more importantly the washing machine/fridge would likely overload the UPS so do not plug these into the battery back-ups side.

3)Yes that is the correct usage of the 2 bottom RJ-45 ports. 

4)Yes that is worded a little strange in my opinion 🙂 perhaps they thought that people would try to use the top data port as an output?

Thanks.

Actually i want to plug in a freezer ( not fridge ) in the surge protected output, peak power being 130W

Also, the cord is too short, can i use a normal extender ( no protections on it, simple ) on it ?

So long as the extension cord you use is of the correct type, isn't a tripping hazard or excessively long, there should be no problem with doing so. Heavier extension cords made for use with large appliances (like refrigerators and freezers) are readily available. I've used them with Smart and Back-UPS products for some time without issue. Be sure that whatever you get maintains the connection to ground, otherwise the surge suppression functionality will be made much less effective.

There are at least two potential problems with connecting an appliance such as a freezer or washing machine to your Back-UPS. Electric motors have enormous starting current demands, and may introduce enough of a sag in line voltage to trigger a switch to battery from the UPS. When the motor is disconnected from its power source, a massive electrical pulse is created as the field within the motor collapses. This might place undue wear on the surge suppression components in the UPS, especially with the motor driven appliance in such close proximity.

That said, I've done exactly that with a much older (~2005) Back-UPS 500 VA "plugstrip" model...it's located in a garage where a chest freezer is plugged into one of the surge suppression only outlets and a small security camera system is on battery backup. I've never noticed a problem with this setup, not even when the freezer cycles on.

ok thank you all.
