Description
WARNING: Disconnect the
power to the Time Switch
and the loads before instal-
lation.
1. Remove the mechanism
from the case by de-
pressing the catch at the
top of the case and pull
ing out, as shown.
CAUTION: Do not
touch circuit board
components since
static discharge could damage the microprocessor.
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.)

• Electrical shock hazard. To avoid fire, shock, or death, disconnect all
power before installing or servicing time switch or connected loads.
• Follow local electrical and safety codes, National Electric Code (NEC)
and Occupational Safety and Health Act Codes (OSHA).
• If the power disconnect point is out of sight, lock it in the OFF position
and tag it to prevent unexpected application of power.
• This time switch must be grounded.
• Do not exceed maximum current carrying capacity.
• Always replace the plastic insulator covering the terminal before
powering ON.
WARNING–Risk of Fire or Electric Shock
