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.
