Optional Equipment
Type of Equipment to be Protected
If the computer is equipped with a modem, the modem should
also be surge protected. Protecting the power line without pro-
tecting the modem line provides only partial protection.
Quality of Electrical Wiring and Service
Wiring should be up to current NEC standards and have veri-
fied good AC grounds. It is important that your computer
system be plugged into a grounded AC outlet when charging
and that all peripherals connected to your system reference the
same AC ground.
Equipment Selection
There are a number of companies that sell quality surge
suppressors. When you are looking for a surge suppressor,
consider these options.
Expect to pay at least $50 for a good quality surge suppressor.
The surge suppressor should be a UL 1449, 497, and 1283 listed
for surge suppression, modem surge protection, and RFI/EMI
noise filtering respectively.
The surge suppressor should have diagnostic LEDs that verify
good AC ground, proper wiring, and proper surge operation.
On/off switches that light are not recommended since they can
produce electrical noise.
The Joule ratings should be a minimum of 480 Joules for the AC
surge circuit.
The Joule ratings should be a minimum of 240 Joules for the
modem.
The modem surge circuit should present low capacitance to the
modem line or it will slow the transmission rate. Capacitance
should be specified at less than 50 picofarads.
Quality surge suppressor manufacturers generally offer a life-
time warranty.
Consider obtaining a protected equipment coverage policy which
insures the equipment in the event of surge damage.
The devices that will be attached to the computer also need to be
surge protected.
