SPEAR™ Single-Phase Recloser System
INSTALLATION AND OPERATION INSTRUCTIONS
MN280048EN June 2016
WARNING
Hazardous voltage . Before applying power to the
control, confirm that male pins of the input power
receptacle are electrically insulated to prevent
unintentional contact with 120/240V AC voltage .
Failure to do so may result in severe personal injury or
death .
T372 .1
IMPORTANT
Connect the control battery before AC power is applied. The
battery must be disconnected prior to shipping or storing
the control.
To keep the battery charged, energize the control with
AC power. See
Customer connections for AC power
. In
addition, if power to the control is not possible a separate
portable charger accessory is available. Catalog Number
KA43ME7001 provides a 120 Volt battery charger to power
individual batteries.
IMPORTANT
To avoid damage to the wiring or batteries, do not transport
the control with the batteries installed.

When shipped from the factory, the battery will be
placed on top of the control enclosure in the carton.
The battery leads will be taped to the battery casing.
Connect the battery plugs into the mating connectors
to complete the battery circuit.
Control power
The control voltage is auto-ranging from 96 to 265 VAC.
The transformer required for power should be a minimum
of 0.5 kVA. This input power is used for multiple purposes
including powering the control and battery recharge circuit,
providing heater voltage (recloser and control), and for
voltage monitoring.
Battery replacement and disposal
The 24 VDC control battery has a life expectancy of four
years. It is recommended that the battery be replaced after
four years or if the battery fails a battery test (after sufficient
recharge time) - whichever occurs first.
otee:
N
Battery life is decreased at higher temperatures.
Dispose expired batteries in an environmentally responsible
manner. Consult local regulations for proper battery
disposal.
Operation upon loss of AC power
The control is equipped with an 8 Amp-Hour 24 VDC lead
acid battery for operation upon loss of AC power. The
control maintains full operation from the battery for 48-hour
maximum (20 °C).
The control continuously monitors the battery voltage.
To prevent battery damage, the control shuts down
automatically upon detection of low battery voltage (below
21 VDC for 60 seconds). Refer to the
section for additional battery monitoring information.
Control programming settings and parameters—including
sequence of events recorder and data profiler—are stored
in non-volatile memory and retained upon loss of control
power. The time/date clock will continue to operate for
approximately four days after loss of control power (battery
and AC power). After this time period elapses, the control
time will be set to 12:00 AM, Jan. 1, 2000.
The control clock may require resetting if the operating
power has been disconnected for more than four days.
Refer to
Service Information MN280012EN SPEAR Single-
Phase Recloser Control Programming Guide
for information
on setting the control clock.
otee:
N
When AC power is present, the control will operate
regardless of back-up battery presence.
If the connected phase loses AC power and the applicable
alarm is configured by the user, the ALARM red indicator
LED will illuminate and the ALARM log on the LCD Display
will indicate NO AC PRESENT
IMPORTANT
If the control shuts down due to low battery voltage before
AC power is restored, and the connected energized recloser
is CLOSED, no electrical operations are possible until AC
power is restored or the battery is replaced and connected.
A control that has shut down due to low battery voltage
before AC power is restored will have a blank LCD display
(no text message shown).
Battery monitoring
Battery monitoring occurs whether AC power is being
supplied or not. Battery monitoring occurs every 1 – 2
seconds. This Battery monitoring does not take place during
a battery test.
The BATTERY LED will illuminate for the following
conditions:
●
●
Battery voltage rises above 37 volts
●
●
Battery voltage drops below 22 volts for 60 seconds
●
●
If the SPEAR single-phase recloser control is operating on
battery power
only
and battery voltage drops below 21
volts for 60 seconds. At this time, the battery disconnect
alarm is issued.
●
●
Battery test failure
If the SPEAR single-phase recloser control is still operating
on battery power and the battery voltage is still below 21
volts for 60 seconds after a battery disconnect alarm has
been issued, the battery is disconnected from powering the
control and the control shuts down.
The BATTERY LED will turn off if the battery voltage is
below 37 volts and above 22 volts for 30 seconds.
