Cambium PTP 650LPU (Lighting Protection Unit) & Grounding Kit

Key Features

• 2 protection methods; line-to-line and line-to-ground

• Shunts excess power to ground within 5 nanoseconds

• Lightweight unit for easy transport to installation location.

Usage

• Lightning strikes are the most typical cause of system outages or failures of mast-mounted equipment, especially when mounted as high as 300m, therefore, lightning protection is critical to minimise the potential for damage

• Cambium Networks strongly recommend that all PTP 650 installations be deployed with the PTP-LPU

• Network operators should always follow best-practices for grounding and lightning protection - doing so will minimise network outages and reduce the associated costs of tower climbs and equipment repair/replacement

• The ruggedised design of the PTP Lightning Protection Unit offers two protection methods: line-to-line and line-to-ground, this ensures that a surge in current induced onto the PTP 650 cabling is diverted away from the ODU

• When installed correctly with the recommended grounding practices (i.e. using solid shielded CAT5e cable), the PTP-LPU quickly shunts the excess current to ground (typically within five nanoseconds)

• By grounding the power surges before they can harm the units, the Cambium Networks PTP-LPU provides radios the best protection from the harmful effects of lightning

• The PTP-LPU’s connections and enclosure are designed for IP 66/67 water and dust protection so they can be installed in the most difficult terrain and environmental conditions

• Easily mounted on a wall or tower with a PTP radio, the PTP-LPU includes a minimum number of components

• The PTP-LPU is small, lightweight, making it extremely easy to transport even up to the highest towers

• Each PTP 650 radio requires two PTP-LPU devices (both included in the single kit part number) – one installed on a tower or a mast adjacent to the radio and another installed at the cable entrance point leading to the building entry point of the network.
