ups for DirecTivo

DOn't waste your tiem looking for one that contains protection for cables
and telephone. Over 95% of surges are thru electrical service only
just buy any UPS you see and use that.

I'd like to put my DirecTivo on a UPS. I currently have a Belkin surge
suppressor, but I haven't found a UPS that handles a phone connection
and two satellite lines, and Belkin doesn't support either a UPS
plugged into a surge suppressor or a surge suppressor plugged into a
UPS. Does anyone know of a good surge suppressor / UPS solution for a
DirecTivo?

I can readily believe that the vast majority of surges cannot be
attributed to a phone or sat line. But my recollection is that taking
a device with a phone or sat line and plugging it in to a surge
suppressor or ups without protecting the data line voids the
suppressor/ups unit warranty and/or protected equipment warranty.

That warranty is another example of 'observation without first
learning reality'. The devil is made obvious in the details. Learn
from another's experience:

"tivo modem?"
I can attest to this... my modem recently fried, and I could not get the
surge protector company to honor the "$20,000 connected devices
warranty". I had everything... the Tivo receipt, the power surge
protector receipt, etc. etc. etc. and jumped through all their
hoops... but they would not honor it because "the coax on the Tivo was
not surge protected". *sigh*

Protection is earth ground. Plug-in protectors forget to mention
that so that you will buy their so profitable product. Do you want a
product with a big profit - or a solution?

Telephone company already installs a 'whole house' protector on your
phone line - for free - because it is so effective and so inexpensive.
Look at what that protector connects to. Earth ground. That is what a
protector is - a temporary connection from each phone line to earth
ground. The protector is a connecting device. Protection is earth
ground.

Your cable and satellite dish also need no protector. Incoming cable
must already be connected 'less than 10 feet' to the same earthing used
by telephone and AC electric. Notice critical characteristics: 'less
than 10 feet', and 'single point earth ground'.

Some installers don't understand the concept. For example, some will
ground to an outside faucet. That is not earthing - too far and other
problems technical.

You want to protect that Tivo? Don't fall for myths such as the
warranty or the $100 myth sold by Best Buy and Circuit City. Tivo
already contains effective protection. Anything at the Tivo that will
protect that Tivo is already inside that Tivo. But its protection can
be overwhelmed if YOU do not earth every incoming utility. Short
connects to earth. Protection distant from appliances so that
protection inside all household appliances is not overwhelmed.

But again, did you even know about that 'whole house' protector
installed free by the telco? Those promoting ineffective protectors
hope you never learn about it - and earthing.

OK. This is secondary protection. Yes, more work to do. A primary
protection system also must be inspected:

The best information I have seen on surges and surge protection is at
http://www.mikeholt.com/files/PDF/Li...ion_May051.pdf
- the title is "How to protect your house and its contents from
lightning: IEEE guide for surge protection of equipment connected to AC
power and communication circuits" published by the IEEE in 2005 (the
IEEE is the dominant organization of electrical and electronic
engineers in the US).

A second guide is
http://www.nist.gov/public_affairs/p.../surgesfnl.pdf
- this is the "NIST recommended practice guide: Surges Happen!: how to
protect the appliances in your home" published by the National
Institute of Standards and Technology (the US government agency
formerly called the National Bureau of Standards) in 2001

Both guides were intended for wide distribution to the general public
to explain surges and how to protect against them. The IEEE guide was
targeted at people who have some (not much) technical background.

If a surge comes in on power wires it can produce a large voltage
difference between power wires and phone wires which can damage
equipment connected to both. And a surge entering on phone wires can
produce a damaging voltage difference to power wires. Plug-in surge
protectors work by clamping the voltage on all wires to the common
ground at the surge protector. That includes power, phone, CATV, ....
All external wires connected to protected equipment have to go through
a plug-in surge protector. This is described in both the IEEE and NIST
guides. It is entirely reasonable to deny a claim above if the coax did
not go through the protector.

Protection is earth ground. Plug-in protectors forget to mention
that so that you will buy their so profitable product. Do you want a
product with a big profit - or a solution?

As clearly described in the IEEE guide, plug-in protectors work
primarily by clamping, not earthing. Both the IEEE and NIST guides say
plug-in surge suppressors are effective.

Telephone company already installs a 'whole house' protector on your
phone line - for free - because it is so effective and so inexpensive.
Look at what that protector connects to. Earth ground. That is what a
protector is - a temporary connection from each phone line to earth
ground. The protector is a connecting device. Protection is earth
ground.

Both the IEEE and NIST guides say plug-in protectors are effective.
For pluug-in suppressors the IEEE and NIST do not agree that
"protection is earth ground."

Do 't fall for the myths promoted by w_. Both the IEEE and NIST say
plug-in suppressors are effective.

Those promoting ineffective protectors
hope you never learn about it - and earthing.

Those promoting "ineffective protectors" include the IEEE and NIST.
Read the guides.

Never seen - a link that agrees with w_.


It is not obvious why Belkin doesn't like a UPS connected downstream
from a UPS. If a UPS does not have effective surge protection built in
that is the recommended setup.

Both Tripp Lite and Fellowes agree with that, although Fellowes has no
2-coax surge suppressors.
