4. Connect Electrical Power
Indoor Locations—Insert the power cord into an 240V electrical
outlet .
Outdoor Locations—If a covered Ground Fault Interrupter (GFI)
outlet is available, insert the power cord into the 240V outlet .
If no outlet is available, the controller 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 2 .5 mm (14 gauge AWG) minimum
with a temperature rating of 68° 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 controller using a 12 mm
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 controller 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 controller .
• 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 .
• 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 Permanent Wiring
The sprinkler controller has a built-in transformer that
must be connected to an AC line voltage source. Check the
back of the sprinkler controller box for power requirements.
Local building and electrical codes usually require that an
approved electrical 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 controller has two holes at the bottom for wire
access. Use a 12 mm Nipple to connect the sprinkler controller
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 controller 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
controller is intended for use with a Ground Fault Interrupter
(GFI) protected circuit.
