BaseStation 3200 Advanced Irrigation Controller Manual
Wiring Surge Protection and Lightning Arrestors
Install lightning arrestors according to the specification below. Each lightning arrestor protects roughly a 300 foot
circle, so you should place a lightning arrestor every 600 feet along the wire path. Ground each lightning arrestor
using an appropriate ground rod or plate as per the Baseline BL-LA01 Surge Arrestor Specification.
Notes
1 Each surge arrestor protects a 300 foot radius of the two-wire path or backbone wire on BaseStation 3200
systems.
2 Install a surge arrestor at the end of the two-wire that is the maximum distance from the controller, or in
a looped topology, at the point of maximum distance from the controller.
3 A stub length must not exceed 50 feet without a surge arrestor (must be within 300 feet of an existing
surge arrestor).
For R-series controllers, a lightning arrestor and appropriate ground rod or plate are required for each moisture
sensor connected to a valve wire that is more than 300 feet from the controller.
Installation Instructions
1. Power off the two-wire when installing devices. Leave 24 to 36 inches of slack on the two-wire to allow for
easy installation and maintenance.
2. Place the surge arrestor in a valve box.
3. Connect the red and black wire from the surge arrestor to the corresponding red and black wires on the
two-wire, making sure that you maintain polarity. You must use 3M™ Direct Bury Splice Kit DBR/Y connectors
on any two-wire connection in a valve box or buried in soil.
4. Connect the green wire from the surge arrestor to the bare copper using a water proof connection.
