Crestron CSP-LSP Lightning Strike Protector
Hardware Hookup
The CSP-LSP can be connected locally to protect a nearby control
system and Cresnet devices. The CSP-LSP can also be connected to
remote Cresnet devices or another CSP-LSP to provide protection to
Cresnet devices that are connected with substantially longer wire runs.
Make the necessary connections as called out in the illustrations below
and on the next page. Refer to “Network Wiring” on page 11 when
attaching the 4-position terminal block connectors. Be sure to carefully
review each hardware connection diagram before proceeding.
Local
Connections Local connections refer to connections made from the CSP-LSP to Cresnet
devices which do not include wire runs exceeding 500 feet or wire runs
situated outdoors, including underground wire runs. Cresnet devices at these
local distance are referred to as local Cresnet devices.
