Changing Power Input Voltage–
Multi Volt Model
ET70415CR
This model can be powered
by any industry standard
50–60Hz AC voltage, 120
to 277 V. To change from
the 120VAC factory setting,
locate the voltage selector
jumper and insert over the
pair marked with the
desired voltage (208, 240, or 277 VAC).
24 Volt Wiring–When Using Bell or Thermostat Wire
Model ET70415CR24 Only
(Load Voltage Above 24 Volts)
This timer must be powered
by 24 VAC, 60 Hz only.
There is no supply voltage
adjustment jumper. If load
voltage(s) are 24V or less,
and/or if the timer power
wiring insulation is rated for
at least 300V, connect timer
power to terminal 1 and 2. If
load voltages are greater than
24V and the timer power wiring insulation is not rated for at least
300V, such as bell or thermostat wire, feed the timer power wiring
through the supplied insulating tube and connect to the two-place
terminal block on the back of the power module. Once installed,
the tubing must extend beyond the enclosure wall and under the
power module so that the timer power wiring remains isolated
from the high voltage load wiring.

SPECIAL INSTRUCTIONS
Load Control Wiring With the logic module removed you
have access to the load control relay terminals. Refer to diagrams
on following pages for terminal designations.
NOTE: Contacts are isolated to enable switching loads of a
voltage different than the timer power voltage. You may need to
connect power to the common (COM) terminals. Add jumpers
as required. Do not mix solid and stranded wires under the
same terminal.
Remote Override Loop override wires in upper compartment
as shown to facilitate removal and installation of logic module.
When installing logic module, you must make sure override wires
are placed in upper compartment, above the power module, or the
logic module will not install properly. Route wiring and insulating
tube through passages in bottom walls of terminal block as shown.
The supplied insulating tube must be used if customer-supplied
field wiring does not have 300 volt or greater rated insulation
(such as bell or thermostat wire). The tubing must extend into the
connector insulator and must extend beyond the enclosure wall
(typically into the conduit).
