INSTALLATION
Connect the 3-phase wires to the terminals marked A, B
and C. Turn both controls fully counter-clockwise.
Connect the control wires to the terminals with the relay
contact markings. NOTE: The contact markings on the
unit are the TRIPPED condition of the contacts.
Apply power. If the contacts do not transfer when power is
applied (NORMAL indicator on), check that all three
phases are present, and of the correct voltage. If all
phases are correct, rotate the VOLTAGE adjustment
counter-clockwise, to the low position. If the contacts still
do not transfer, remove power from the unit. Reverse any
two of the three input wires, and re-apply power. The
contacts should transfer to the normal condition (normally-
open contact closed, NORMAL indicator ON).
ADJUSTMENT
NOTE: During adjustment, you may want to install a
jumper across the control contacts, to prevent cycling the
load on and off.
Set the trip delay to .2 seconds.
Rotate the VOLTAGE adjustment slowly clockwise until the
contacts transfer to the failed condition (TRIPPED indicator
lit).
Slowly turn the VOLTAGE adjustment counter-clockwise,
until the contacts reset to the normal condition (NORMAL
indicator on).
WARNING
The Model 264 is not to be used in applications
where voltages to be monitored or switched
will exceed voltage specifications for the
particular unit. See ‘Adjustment Range’ in the
Specifications table on the reverse side of this
data sheet.

Installation Instructions
If you installed a jumper across the control contacts to
prevent load cycling, remove it now.
Set the SECONDS adjustment to the desired amount of
trip delay. ThIs trip delay will prevent most nuisance
tripping; however, if nuisance tripping does occur, turn the
VOLTAGE adjustment slightly farther, counter-clockwise.
In making adjustments to eliminate nuisance tripping,
the VOLTAGE adjustment should be rotated in very
small increments, until the true nuisance trips are
eliminated.
