MEGA-TEK 25 Series
Telephone Circuit Protection

The MEGA-TEK 25 Series surge suppressor installs directly in line with existing AMP-TYPE 25-pair connectors. The close proximity to the KSU/PBX preserves the MEGA-TEK's response time, clamping level and ground reference by reducing lead lengths.

The MEGA-TEK's unique design maximizes surge suppression performance while reducing hardware and labor costs to install. The MEGA-TEK is a UL 497A telephone secondary protector. The product is available in three application-specific models.

FEATURES

• AMP-TYPE Connectors

• Automatic Recovery—Resettable Fusing

• 25-Pair Protection

• High-Energy Silicon Technology

• UL 497A Listed

• ‹1 Nanosecond Response Time

INSTALLATION

The hybrid design of this product includes series resistance. Do not place this product in service on any signal lines capable of more than 150 milliamperes continuously.

Installation Procedures
1.	Never install telephone wiring during a lightning storm.
2.	Disconnect telephone line at the network interface before installing the secondary protection.
3.	The MEGA-TEK Series is intended for indoor use only. Plug the female AMP-TYPE connector from the unprotected Telco cable into the male AMP-TYPE connector on the MEGA-TEK Series. This is the LINE side.
4.	Plug the male AMP-TYPE connector from the local equipment cable to be protected into the female AMP-TYPE connector on the MEGA-TEK Series. This is the EQUIP side.
5.	Bond the green #12 AWG stranded ground wire from the MEGA-TEK Series Series to AC Power Ground or Building Approved Ground. For recommended grounding techniques, refer to EDCO Technical Bulletin #1090.
