MODEL ET1700 Series

Installation and User Instructions

WARNING Risk of Fire or Electric Shock

•Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.

•Installation and/or wiring must be in accordance with national and local electrical code requirements.

•For outdoor locations or wet locations (rain-tight), conduit hubs that comply with requirements of the UL514B (standard for fitting conduit and outlet boxes) are to be used.

•This enclosure does not provide grounding between conduit connections. When metallic conduit is used, you must also install grounding type bushings and jumper wire.

•For plastic enclosures, bonding between conduit connections is not automatic and must be provided as part of the installation.

•Use #18 - #10 AWG wires, rated at least 75°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 no wire insulation under the terminal plate on the time switch connector. Firmly tighten terminal screws.

•Do not remove insulator that is covering terminals.

•KEEP DOOR CLOSED AT ALL TIMES when not servicing.

NOTICE

•Do NOT touch circuit board components, contact can create a static discharge, which can damage the microprocessor.

Description

The Intermatic ET1700 Series Electronic 7-Day Time Switch automatically switches loads to a preset weekly schedule with to-the- minute accuracy.

The independent 7-day programming provides complete flexibility for applications where load switching differs each day of the week.

Use the ET1700 series as an ON/OFF timer in applications requiring 7-day load control such as lighting, air conditioning systems, pumps, etc. Each load output of the Time Switch can support up to 14 timed ON and 14 timed OFF events per day. The program can be overridden by pushing the ON/OFF load override button(s).

The ET1700 Series Time Switch is designed to directly switch tungsten or ballast loads up to its rating, and inductive or resistive loads up to 30A at 120, 208, 240, or 277 VAC.

Installation Instructions	Snap out catch

Tilt top forward

1.Remove the mechanism from the case by depressing the catch at the top of the case and pulling out, as shown.

Slide down to remove battery case

2.Set voltage selector for desired input voltage. The timer is shipped with voltage set for 120 VAC. To operate at 208, 240 or 277 VAC, move the selector switch to the desired setting as marked on the circuit board. See location A in Rear View above and detail at the right.

3.The timer is shipped with DST (Daylight Saving Time) enabled. To disable DST, insert a jumper at location marked DST. See location B in Rear View above and detail at the right.

4.ET1725C ONLY—Decide whether you want to control multiple loads simultaneously (SIM), independently (IND), or with a 2-second pulse (PUL) (e.g., for use with mechanically held contactors or bell ringing applications), and make sure the jumper is positioned accordingly. See location B in Rear View above and detail at the right. (The unit is shipped with the loads set for IND.)
