Indoor-Outdoor Controllers
tter
All our Weather-resistant Indoor/Outdoor controllers can run at temperatures
the between 35 and 140 degrees Fahrenheit (0 to 60degrees Celsius). Storage tem-
perature is -4 to 149F (-20 to 65C).
Direct sunlight can easily increase temperatures inside the Controllers so chose a
r.
shaded location.
The controllers are weather-resistant to UL-50 and ETL
be placed in areas where continuous water could cause damage.
Caution: Do not open the Controller when it is raining.
To make installation easier the Controller has a removable door. Remember to
leave at least 7ins (18cm) to the left of the controller box for the door to swing
open after installation.
Check the model number of your timer: various models are configured differently
to meet national requirements, look for the section covering the model number
on your controller. The model number can be found on the back of the housing,
together with other useful information.
Models 57694, 57696, 57699, 57692
are for installation in Australia, New Zealand, and South Africa using the fit-
ted line cord.
Models 57974, 57976, 57979, 57972
are for 110/117VAC operation and are suitable for either wall-hanging installation
using the line cord fitted or permanent installation. You need to decide which type
of installation you are going to use. Ensure that you have the appropriate electrical
power available at the location you intend to use. If used outdoors with the line
cord, a suitable weatherproof power outlet must be available.

Using the lower mark on the template, affix a No. 8 screw (included), again
leaving the head protruding.
Slip the slotted keyhole in the back of the Controller over the extended upper
screw and allow the lower screw to recess into the lower hole in order to pre-
vent the Controller from swinging. [See Fig.19].
The line cord may now be inserted into the power outlet.
Proceed to section 7.
Installation using permanent wiring
Preparing the Controller for Permanent Installation
Before commencing to install the controller you must remove the fitted line cord
and replace with the pigtail wires provided.
Take off the terminal compartment cover by unscrewing the two screws and
pulling the plastic cover forward. [See figure 18], this reveals the AC Power
Cover [Figure 21].
Remove the rubber weather plug from the hole in the center and unscrew the
one fixing screw, pull the plastic cover forward to reveal the AC wiring.
Use a punch to create a hole in the blind Bottom Mounting Hole on the back
of the controller box [Figure 19: Bottom Mounting Hole].
Loosen the screw on the cord restraint and the three screws on the terminal
block and remove the line cord completely.
Feed the three wires of the pigtail through the exit nipple, under the strain
relief, and cross to the terminal block. Fasten the wires to the terminal block
ensuring that the black wire is connected to the Live terminal marked L, the
white wire is connected to the Neutral terminal marked N, and the green wire
is connected to the Earth terminal marked E. Ensure that the terminal screws
and the strain relief screw are all firmly tightened. Check that the wires are
clear of any obstruction and will not be trapped by the AC Power Cover when
it is replaced.
Replace the AC Power Cover and screw tight, do not force into place, if resis-
tance is met check that no wires are trapped.
The Controller is now ready for permanent installation; follow all the instruc-
tions for the following models to complete the installation. (use expanding
anchors in plaster or masonry if necessary).
