Installation Category
CPS6000-M2 is suitable for connection to ac utility systems where the expected level of lightning
surges complies with ANSI C62.41 Category B or IEC 60664-1 Overvoltage Category II.
A service entrance surge protector is required in applications where the installation categories can
not be classified as being compliant to either ANSI C62.41 Category B or IEC 60664-1
Overvoltage Category II.
CPS6000-M2 rectifiers have been tested for repeated lightning surges typically found in an
Overvoltage Category III installation; however, a service entrance surge protector is
recommended in cabinet applications to bring the power feeds in compliance to the installation
categories above. The service entrance protection should be coordinated with the protection
provided in the power modules.
The power module provides common-mode protection via a 320V MOV in series with a 2500V
gas-discharge device and differential-mode protection via a 320V MOV in series with a 3.5A fuse
