General Safety Information

WARNING: Disconnect all power before installing or servicing
this time switch or its connected loads.

1. Follow all local electrical and safety codes, National Electric
Code (NEC), as well as Occupational Safety and Health
(OSHA).

2. If the power disconnect point is out of sight, lock it in the “OFF”
position and tag it to prevent unexpected application of power.

3. This time switch case must be grounded.

4. Do not exceed the maximum current carrying capacity of this
time switch.

5. Always replace the plastic insulator covering the terminal
before turning power “ON”.

be overridden by pushing the ON/OFF load override button(s).This time
switch is designed to directly switch tungsten or ballast loads up to the time
switch rating and inductive or resistive loads up to 30 amps at 120, 208,
240, or 277 volts.

Installation

WARNING: DISCONNECT THE POWER TO THE TIME SWITCH AND
THE LOADS BEFORE INSTALLING THIS TIME SWITCH.

1. Remove the mechanism from the case by depressing the catch at the
top of the case and pulling out. (See Figure #1) The timer is shipped set
for 120VAC operation by means of a selector switch. To operate timer at
208, 240 or 277 VAC, move the selector switch to the appropriate setting,
as marked on the circuit board (See Figure #2). The timer is shipped with
Daylight Savings Time (DST) enabled. To disable this feature insert a
jumper at location marked DST. The ET8215C timer is shipped with the
loads set to be independently controlled (IND), the outputs can be
changed to simultaneous or pulsed operation by moving the jumper to SIM
or PUL respectively. (See Figure #3 and wiring diagrams.)

CAUTION: DO NOT TOUCH THE CIRCUIT BOARD COMPONENTS
SINCE STATIC DISCHARGE COULD DAMAGE THE MICROPROCES­SOR.

2. Mount the time switch in the desired location using the three mounting
holes that are provided. Mount the time switch at eye level, if possible,
providing sufficient room to the left of the enclosure for the cover to swing
open fully. (See Figure #4)

3. Replace the mechanism in the case.

4. Lift the left side of the insulator off of the retaining post and pivot it up
and away to expose the terminal strip.

5. Strip the supply and load wires by removing 1/2 inch of insulation. DO
NOT USE
under the proper terminal plates and tighten the screws firmly. Use AWG
#10 through #18. Connect ground wire to grounding terminal at bottom of
case.

6. Replace the plastic insulator.

7. Be sure that the batteries are functioning properly. This can be checked
by making sure the display is visible. If the display has scrambled
information, press the [RESET] switch. Note that the batteries can easily
be replaced without removing the time switch mechanism or field wiring.
Simply press in and downward (in the direction of the arrows) on the
battery cover. It is recommended that the batteries be replaced with
“AAA” industrial grade alkaline cells at two to three year intervals as part
of the normal time switch maintenance observing battery polarity markings
when installing. No other maintenance is required.
