CPS3200U output circuits are suitable for connection to telephone lines that are equipped with

primary lightning protectors consistent with UL 497. The user must provide protection on each

copper pair to a level corresponding to a CommScope 3C*EW Gas tube primary protector or

equivalent gas tube protector [For example: 3C3EW provides the part in a red color]. This protector

has a voltage breakdown range of 265-465 Volts and an impulse spark over range of <265-700 Volts.

The 5-Pin protector must be marked as a "special circuit" consistent with the marking protocol in the

users network. Protectors are provided by the telco customer.

Network equipment and components along the powering circuit shall have suitable insulation

resistance at 200 Vdc from each conductor to ground and a total insulation resistance suitable for

400 Vdc from line to line.
