Federal Communications Commission (FCC) Notice for ET8415 Time Switch
This document explains the setup and conguration of the Intermatic ET8415 4-Circuit Electronic Astronomic
7-Day Time Switch. The ET8415 time switch automatically switches loads to a preset weekly schedule. The time
switch can support up to 28 xed ON and 28 xed OFF events (56 total) and up to four Astro events. Each event
can be applied to any combination of circuits and days.
The time switch features an LCD and panel-mounted control buttons to set, review, and monitor the time switch
functions, including enabling or disabling Daylight Saving Time (DST) and conguring DST switchover dates.
Follow these instructions to complete the installation and programming for the ET8415 time switch.

Installation
MODEL ET8415CR
NOTICE
Follow these instructions to install the time switch.
1. Open the time switch enclosure door.
2. Press the catch at the top of the case and pull out the mechanism from the case.
3. Choose a knockout to remove from the enclosure.
NOTE: There are five 1/2 inch to 3/4 inch combination knockouts available. There are
two on the bottom of the enclosure, one on each side, and one on the rear.
4. Insert a athead screwdriver into the slot of a 1/2 inch knockout and punch loose and
remove.
NOTE: If a 3/4 inch knockout is needed, remove the 1/2 inch knockout first, then the
outer ring. Smooth edge if necessary.

WARNING Risk of Fire or Electric Shock
• Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.
• More than one circuit breaker or disconnect switch may be required to de-energize the equipment before servicing.
• Bonding between conduit connections is not automatic and must be provided as part of the installation.
• Installation and/or wire must be in accordance with National and Local Electrical Code requirements.
• Use #14 - #8 AWG wires, rated at least 90°C - COPPER conductors ONLY.
• If the power disconnect point is out of sight, lock it in the OFF position and tag it to prevent unexpected application power.
• Make sure there is not wire insulation under the terminal plate on the time switch connector. Firmly tighten terminal screws.
• Replace plastic insulator covering terminals before powering ON.
• KEEP DOOR CLOSED AT ALL TIMES when not servicing.

5. Place the enclosure in the desired location, position at eye level, and provide space for the enclosure door to swing open fully.
6. Drill the holes and then clean out each hole.
7. Insert plastic anchors into the holes, if needed.
IMPORTANT: If you are bringing power wires and wires for connecting applications through the back of the enclosure,
connect the wires before mounting the enclosure. Refer to the wiring diagrams in this manual.
8. Insert the top screw into the top hole and tighten. Hang enclosure.
9. Insert the remaining screws into the other holes and tighten.
10. Replace the time switch in the enclosure.
11. Remove and retain the screw that secures the plastic insulator.
12. Lift the left side of the plastic insulator off the retaining post and pivot it away to expose the terminal strip.
NOTE: Do not remove the insulator.
13. Strip the supply and load wires to 1/2”. Use AWG#14-#8 copper 105º conductors only. Torque to 15.6 lbf-in.
14. Connect the wires to the proper terminals on the time switch connector and tighten the screws firmly.
See wire diagrams.
15. Connect ground wire to grounding terminal at the bottom of the enclosure.
NOTE: Make sure no wire insulation is caught in the terminal.
16. Return the insulator to its original position and replace the screw.
17. Close the enclosure door.
18. Apply power to the time switch.

The time switch operational modes enable users to control multiple loads simultaneously (SIM), independently (IND), or with a
2-second pulse (PUL). In PUL mode an ON event or manual override causes the rst circuit to turn ON for two seconds, then OFF. An
OFF event or manual override causes the second circuit to turn ON for two seconds, then OFF. Loads 1 and 2 and 3 and 4 can be set to
different operational modes.

To combine Astronomic and xed events, only program one event in each ON/OFF event pair for both Astro and Fixed events. For
example, a combination Astro and xed event schedule could be a Sunset ON and a Fixed event off for 10 P.M. It is recommended to
determine your facility schedules in advance and then program the time switch. If applicable, different combinations can be congured
for different loads.
Follow these guidelines to congure a combination Astro and Fixed Event schedule.
