Unscrew the wire-nuts from the three wires connecting
the power cord to the timer.
Remove the metal bracket holding the power cord to the
back of the wiring compartment and pull the cord out
through the bottom of the cabinet.
Route the three wires from an external power source into
the wiring compartment.
Using the wire-nuts, connect the external power wires to
the internal connection wires inside the wiring compart-
ment.

WARNING: Be sure to connect the colored coded exter-
nal wires to the same color internal connection wires, as
follows:
•
Black wire (power)
•
White wire (neutral)
•
Green wire (ground)
Verify that all wiring connections are secure, then replace
the wiring compartment cover.

Step 3. Connect Valve Wires To Timer
Valve Connections
Use direct burial cable to run wiring from the timer to
valves in the eld.
Connect a color coded wire from the direct burial cable to
either wire on the valve.
Connect the remaining wire on each valve to a “common”
wire which then connects to the timer.
NOTE: Use water-tight connectors for all wire splice con-
nections. Depending on your landscape setup, you may
need to run extension wires for the power and common
connections.
Timer Connections
Connect the color coded power wire from each external
valve (or zone) to the corresponding zone number on the
terminal block
c
WARNING: To prevent damage to the timer, connect only
ONE valve to each open zone slot on the terminal block.
Connect the common wire to one of the COMMON slots
on the terminal block.
NOTE: Do not remove the yellow jumper wire on the ter-
minals marked RAIN SENSOR.
Check that all wiring connections are secure.
