O & M Manual for the RLC1
Automatic Transfer Switch
26.
Utility - Monitoring and Protection
Provides Utility monitoring and protection functions. If the
Utility fails then the Automatic Transfer Controller will begin
the sequence of operations necessary to transfer the load to
the Generator. All Feature 26 monitoring and protection
functions are "Failsafe" operations.
26M. Generator Utility Sensing
Allows for the switch to operate with generators that have
internal utility sensing. This option comes as a kit that
needs to be field installed.
32G. Time Delay Neutral (TDN)
This feature provides a time delay in the neutral position
during the transfer and re-transfer operations during which
both the Utility source and the Generator source are discon-
nected from the load circuit. TDN cannot be implemented
on a transfer switch using a 2-position contactor.
Jumper selectable at Disable (0 seconds) or Enable (2 sec-
onds).
37A. Service Equipment Rated Transfer Switch
This feature provides the label "Suitable for use as Service
Equipment" and the features necessary to meet the require-
ments for the label.

SECTION 4: INSTALLATION AND WIRING
4.1 General
Eaton ATSs are factory wired and tested. Installation requires sol-
idly mounting the enclosed unit and connecting the power cables
and the auxiliary pilot circuits. Physical mounting procedures and
power cable connections are covered in this section.
Once a transfer switch is properly installed and wired, it should be
mechanically and electrically checked for proper installation and
operation. The procedures for these initial mechanical and electri-
cal checks are outlined in Section 5 of this manual.
BE CERTAIN THAT THE DOOR IS PROPERLY INSTALLED BEFORE
THE TRANSFER SWITCH EQUIPMENT IS PUT INTO SERVICE. THE
DOOR PROVIDES PROTECTION FROM DANGEROUS VOLTAGES AT
THE LINE AND LOAD TERMINALS WHEN THE EQUIPMENT IS IN
OPERATION. FAILURE TO DO SO COULD RESULT IN PERSONAL
INJURY OR DEATH.
