Surge suppression unit
Structures, equipment and people must be protected against power surges (typically caused by
lightning) by conducting the surge current to ground via a separate preferential solid path.
The actual degree of protection required depends on local conditions and applicable local regulations.
To adequately protect an ePMP installation, both ground bonding and transient voltage surge
suppression are required.
Network operators should always follow best-practices for grounding and lightning protection. Doing so
will minimize network outages and reduce the associated costs of tower climbs and equipment
repair/replacement.
Note Lightning-prone installations can be improved by:
Installing a surge suppressor near the device (transient surge suppression)
Grounding the device to the pole (ground bonding)
Lowering the device/dish such that it is not the highest metallic object on the pole.
Gigabit Ethernet Surge Suppressor
The Gigabit Ethernet Surge Suppressor is critical for lightning protection to minimize
the potential for damage.
