ENVIRONMENTAL RATINGS

Ambient Temperature: –40F to 130F

Humidity: 0-95% RH, Non-condensing

WIRING CONNECTIONS

Screw clamp terminals for up to 2 AWG #8 wires

per position. For supply connections, use 8AWG or larger wires suitable for at

least 105° C. Use copper conductors only.

LIGHTS

Power LED (Orange) – Light illuminates when power is applied to

the timer

Status LED (Green) – Light illuminates when power is applied to load.

INSTALLATION

CAUTION: Before wiring or service, power to this time switch and the

equipment it controls must be turned off. Turning off the timer switch only

will not prevent a shock hazard. Replace cover plate within housing before

supplying power to time switch. Installation should be performed by a licensed

electrician only. Before installing this product read all instructions carefully.

Remove protective cover panel within time switch housing by removing

screws located above timer face and at the bottom of the cover panel.

DIPSWITCH CONFIGURATION

WARNING: Failure to properly conﬁgure the dipswitch will result in

damage to the unit and void the warranty! Before installing and wiring the GE

Time Switch, proper conﬁguration must be selected. This is accomplished as

follows:

INPUT VOLTAGE DIP SWITCH SETTING:

1. Do not apply power to the timer prior to setting correct Input Voltage DIP

switch.

2. Determine the input voltage which will be applied to the timer (i.e. L1 and

L2/N terminals, see wiring diagrams)

3. Set the DIP switch according to the diagram below.

NOTE: Unit is shipped with DIP switches set for 277VAC Input Voltage

CAUTION: Do not check circuits by “sparking” wires to terminals. Damage to

the timer may result.

NOTE: For outdoor locations (model GE 15252), rain tight or wet location

conduit hubs that comply with requirements of UL 514B (standard for ﬁttings

for conduit and outlet boxes) must be used.

1. Remove 2 screws retaining the interior cover panel and remove panel

by prying out with a thin blade at the top.. Select knockouts to be used.

Remove the inner 1/2” knockout by inserting a screwdriver in the slot

and carefully punch knockout loose. Remove slug. If the 3/4” knockout

is required, remove the outer ring with pliers after removing the 1/2”

knockout. Smooth edges with knife if necessary.

2. Place enclosure in desired mounting location and mark the three

mounting holes.

3. Drill holes for #10 screws, start screws in holes.

4. Place enclosure over screws and tighten screws.

5. Connect conduit hubs to conduit before connecting the hubs to the

enclosure. After inserting hubs into enclosure, carefully tighten hub lock

nut. Do not over-tighten.

Dipswitch Setting continued:

6. Install in accordance with all applicable National and Local code

requirements. See Figure 1 and wiring diagrams.

7. Replace interior cover panel and 2 screws.

GROUNDING:

This enclosure is of plastic construction and does not require a ground

connection and does not require bonding in pool applications.

This enclosure does not provide grounding between conduits. When using

non-metallic conduit or cable, connect the ground wires of all cables together

with a wire nut. When metallic conduit is used, use grounding type bushings

and a jumper wire between each conduit.

OPERATING INSTRUCTIONS:

When the Time Switch is installed and power applied, the timer’s dial will turn

clockwise maintaining time. The pointer on the face of the dial points to the

current time

1. Locate the segments around on the outer edge of the timer’s dial. These

segments, each representing 30 minutes, can be pushed down and away

from the edge of the dial (try using the tip of a pen or pencil). Conversely,

segments that have been pushed down can be easily pushed back up by

hand. Be sure all segments are pushed up before programming. Select a

time period (or periods) you want the device turned on, then push down

ALL the segments that fall on or within that time period. For example,

to have the timer turn a device on at 10PM and off at 2AM, push down

the segments representing 10PM and 2AM, and ALL the segments in

between. You may need to turn the dial clockwise to access the desired

segments.

2. Rotate the timer’s dial clockwise until the pointer on the face of the dial

points to the current time of day. Note: Nighttime hours (from 6:30 PM to

6:30 AM) are highlighted with a grey background.

3. Set master switch to the TIMER position.

4. To override timer program and control output load manually:

• set master switch to OFF (center position) to turn load OFF

• set master switch to ON (bottom position) to turn load ON

5. This is a Timer Control and should not be used for power disconnect.

Turn power off at main panel before servicing this switch or the

equipment it controls.

In case of power failure, reset the time of day as explained in step 2.
