Static Electricity is Not Your Friend
We cannot stress enough that power surges,
voltage spikes and electrostatic discharges are harmful
to your electronic equipment.
The electronic / computerized units commonly used
today are more efficient and more reliable than in
years past. However they are more sensitive to electrical
fluctuations as well.
According to susceptibility data, most integrated
circuits are susceptible to ESD levels of 2000V or
less. Your fingers cannot feel 3,000V but your computer
based systems can. Though systems are shielded, even
well shielded systems can be damaged by high voltage
electricity. Walking across a carpet on a dry cold
winter day can build up a charge grater than 30,000V.
Nylon Clothes can produce 21,000V. Wool and Cotton
clothing can produce 9,000V and 7,000V respectively.
AVOID STATIC ELECTRICITY
Keep Humidity as high as reasonable
Discharge yourself before handling sensitive components
Spray a solution of fabric softener and water on carpets
in traffic areas.
Wipe a fabric softener sheet on surfaces near your
telephony and computer equipment. (Avoid using on
tiled floor surfaces, as they can become quite slippery)
POWER SURGES, OUTAGES CAN CAUSE PERMANENT DAMAGE
Problems with Voicemail systems may actually be masking
primary problems associated with power damaged KSUs
from past electrical surges. Even if there is no visible
damage Power Surges and spikes may weaken delicate
computer / telephony components that may appear later
as irreparable damage.
Using filters and battery backup / surge protection
in front of your electronic telecommunication units
can eliminate costly problems caused by brown outs
and power surges.
Lightening Protection may also be an option in protection
fro your company’s equipment. Dependable gas
tube protectors, from Porta-Systems, guard sensitive
equipment from dangerous voltage surges.
RECOMMENDATIONS FOR BATTERY BACKUP UNITS
Battery Backup Units (BBU) / UPS (Universal
Power Supply) with surge protection typically suggested
for use with a computer station may not be sufficient
to provide adequate protection or power supply timing
to your PBX/KSU/DSU. The following units, which meet
telephony Manufacturer’s recommendations provide
good surge protection and BBU time to safely shut
down systems until power is restored.
MINUTEMAN UPS - MM1000PRO or the MBK520 for computer/VM
Stations
APC SMART-UPS - SU700XL or SU1000XL
MGE –EVOLUTION 1100 or 1500 UPS
TRIPPLITE UPS - SmartOnLine System
CYBERPOWER – C910-1036P

A
Health and Safety Guide for your Workplace
If you discharge static electricity on a computer
circuit board, the spark-can severely damage the circuitry.
The sudden surge of electrons can easily fry microchips
in the computer.
Also Remember to keep all magnets away
from sensitive electronic telephone components and
computer equipment.
