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.

Digital Time Switch

Indoor/Outdoor

NEMA 3R-Rated

Enclosure

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.

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.

120VAC

277VAC (Default)

208~240VAC

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.

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.
