INSTALLATION
The Model 2601 is a socket-mounted voltage sensing
relay. The pin configuration diagram, below and on the
unit, shows the contacts in the power off or tripped
condition. Connect the wiring to the socket as shown in
the Typical Application Diagram.
Observe the proper
polarity of the input voltage for DC models
.

ADJUSTMENT PROCEDURE
NOTE:
When adjusting the Model 2601 you may wish
to jumper the control circuit contacts to prevent tripping
the load on and off. A variable voltage source and a
digital voltmeter provide the most accurate means of
calibrating the trip point.
For under voltage sensing
, slowly rotate the
adjustment pot counter clockwise until the indicator
light just illuminates and the contacts transfer. Any
voltage below this level will now trip the relay.
A reasonably accurate voltage setting can be obtained
by using only the operating line voltage. Apply the
voltage and follow the adjustment procedure above.
Any voltage approximately 2% to 4% below the nominal
voltage will now trip the relay. To prevent nuisance
tripping you may need to turn the adjustments slightly
lower as needed.

GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 2601.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
NOTE:
When installing the Model 2601 in areas of high
humidity or contamination, the base area and all exposed
metal parts of the socket should be coated with a good
quality silicon grease such as Dow Corning* DC-4 or DC-4x.
Insert the relay into the socket and wipe off excess grease
from around the base. This will help prevent moisture and
other contaminants from entering the base and socket areas.
