2.2 DESCRIPTION

The Patton Model 546 and Model 547 data line surge protector

guards V.35 data ports against damage and data loss due to transient
surges. Three versions are available. Model 546MF protects 19 lines,
Model 546/34MF protects all 34 lines, and Model 547MM protects 18
lines. Whether due to nearby lightning strikes, electric motors,
florescent lights or the normal operation of AC power protection
equipment, data line transients can be hazardous to V.35 hardware.
The Model 546 and the Model 547 protectors are equipped with a
heavy duty braided metal strap to shunt harmful overvoltages safely to
ground.

The Model 546 and Model 547 surge protectors are CE marked for

EMC directive 89/336/EEC and IEC 801-5.

WARNING: Should your equipment or building be subject to
direct lightening strike, this product will not provide complete
protection.
