Key Installation Practice #4

Waterproof all communication cable splices using DBY-6 and DBR-6 by 3M

. If using other waterprooﬁng method,

verify that it is rated at 40 VDC minimum.

Key Installation Practice #5

Two Wire Decoder Systems must be properly grounded in order to protect against lightning surges. The communication

cable must be grounded no further than 1000’ (305m) from any decoder. In high lightning areas, Toro recommends

that a decoder be no more than 500’ (152m) from a surge device/ground plate, or total of 1000’ (305m) between

ground plates. The surge device must be a Toro DEC-SG-LINE and must be grounded to a copper plate that is at least

4’’ x 36’’ x 0.064’’ (10.16cm x 91.4cm x 1.6mm). The minimum distance between the surge arrestor and the ground plate

should be 3’ (91.4cm). Toro recommends a split bolt connection to be used to connect the surge device to the ground

wire with a DBM waterproof connector.

Note: A best practice on installation

to avoid surge/lightning damage is to

locate the decoder as close to the

valve(s) as possible.

Key Installation Practice #6

Do not loop or connect the decoder cable back to the controller board circuit. All wire path from the daughter board

will end at a decoder. Communication cables not being used must be capped and water proofed.
