4. Connect Electrical Power
Indoor Locations – Insert the power cord into an 110V electrical
outlet .
Outdoor Locations – If a covered Ground Fault Interrupter
(GFI) outlet is available, insert the power cord into the 110 volt
outlet . If no outlet is available, the timer must have the wiring
permanently installed (*see figure 5)
• Turn off the AC power at the AC circuit breaker and
apply an appropriate safety lockout . Verify that the power
has been turned off to the installation site using an AC
voltmeter set for the correct measurement range .
• Use power feed wire of 14 gauge (AWG) minimum with
a temperature rating of 155 degrees Fahrenheit (68
degrees Celsius) or higher .
• Install the conduit and associated fittings . Connect the
AC electrical power wiring to the source by following all
the right codes and local standards .
• Connect the junction box to the Timer using a ½" nipple
(Junction box and nipple not included) . [See Figure 5]
Connect the source power conduit to the entrance of the
junction box, following all the appropriate codes .
• Take the cord (running from the timer to the junction box)
from the junction box and cut it to length . Remove the
outer insulation (from cord) to expose the three wires .
• Connect the source wires to the wires extending from the
sprinkler timer .
• For USA: Take care to follow the correct color code .
Connect the Green for Ground, Black for Live, and White
for Neutral . Often the source ground may be bare copper
conductor rather than green wire .
• For Europe: Live is Brown and Neutral is Blue, there is
no ground connection required . Be sure that all wires are
connected to the proper source wire .
• Make sure all connections are made with code-approved
insulated connectors .
• Be sure to place a weatherproof gasket and lid on the
junction box .
• Turn AC power on at the AC circuit breaker .
Important: Installation Using Permanant Wiring
The sprinkler timer has a built-in transformer that must be
connected to an AC line voltage source. Check the back of the
sprinkler timer box for power requirements. Local building
and electrical codes usually require that an approved electrical
8
conduit and electrical fittings be used to connect exterior wall-
mounted equipment to AC power. Please check local codes. Any
permanent connection should be made by a licensed electrical
contractor in accordance with the requirements of the National
Electrical Code and other state and local codes.
This sprinkler timer has two holes at the bottom for wire access.
Use a 1/2" Nipple to connect the sprinkler timer to a standard
electrical junction box. Both connector and junction box must be
UL Listed or equivalent or comply with IEC or EN standards or
equivalent.
The wire can be buried in the ground; however, for more
protection wires should be pulled through electrical conduit and
buried underground. Be careful to avoid burying the wires in
locations where they could be damaged by digging or trenching in
the future.
Caution: Do not connect the sprinkler timer to one phase of a
three phase power system used by a pump or other electrical
equipment.

Note: For outdoor applications it is recommended that a qualified
electrician complete the installation in accordance with electrical
codes and regulations. When used outdoors this sprinkler timer is
intended for use with a Ground Fault Interrupter (GFI) protected
circuit.
