Eaton Tandem ELF Current-Limiting Dropout Fuse Installation And Operation Instructions

20 OPERATION AND INSTALLATION INSTRUCTIONS MN280075EN July 2018
Form 6 microprocessor-based rack-mount recloser control
Standard default supervisory input control and
output status contacts
The standard Form 6 rack mount recloser control includes
three control contact inputs and five status contact outputs.
The standard default I/O terminal connections are identified
in Figure13. A discrete interface board accessory is
available if additional I/O is required. The accessory includes
eight control contact inputs and eight status outputs as
identified in Figure14.
All of the control inputs and status outputs are user-
configurable via the Idea Workbench. To avoid configuration
time, the most common control inputs and status outputs
are included as default values. Refer to Figure13 and
Figure14 and Table6, Table7, and Table8. Refer to
Service Information S280-70-4 (ProView 4.X.X) or S280-70-
21 (ProView 5.X.X) Form 6 Control Programming Guide for
additionalinformation.
NOTICE
External leads must be shielded and the shield must
be grounded at both ends. Terminate each lead with
a 320 VAC, 150 Joules metal oxide varistor (MOV), or
equivalent, at the remote end. Attach MOVs between
the leads and ground. Failure to properly shield and
protect leads can result in equipment damage and/or
unintentional operation.
IMPORTANT
Shielding and Surge Protection of Supervisory Cables
All supervisory operation and control monitor leads must
be protected within shielded cables. Refer to Figure15 or
Figure16 as appropriate.

Before placing the control and the recloser
into service
Prior to placing the control and recloser into service,
the following installation procedures must be properly
completed and verified:
CAUTION
Equipment misoperation. Do not connect this control
to an energized recloser until all control settings have
been properly programmed and verified. Refer to the
programming information for this control. Failure to
comply can result in control and recloser misoperation,
equipment damage, and personal injury. G110.3
1. Removable insert labels changed. (Not required –
user-preference option.)
ote:N Refer to Using removable inserts section in this
manual for more information.
2. Control properly mounted for the installation.
3. Recloser installed according to all locally approved
standards and practices.
4. AC and DC disconnect switches installed.
5. Shorting CT terminal-type block installed.
6. Control wiring between control and recloser properly
connected and supported.
7. Control and recloser properly grounded in accordance
with guidelines in this manual and the applicable
recloser manual.
8. DC power and AC voltage sensing connected to
thecontrol.
ote:N The control Power Save feature will turn off the
backlit LCD display and all LEDs if no front panel
keypad is pressed within ten minutes.
ote:N If fuses are blown, check control power polarity.
Replace fuses and re-energize control.
