SPEAR™ Single-Phase Recloser System
INSTALLATION AND OPERATION INSTRUCTIONS
MN280048EN June 2016
Alarm condition
During a battery test a 5Ω, 55 watt resistor is placed across
the battery terminals for approximately 5 seconds. The
SPEAR single-phase recloser control measures the battery
voltage, if the voltage drops below 22.8 VDC the BATTERY
LED illuminates (Figure 37) and a battery alarm is issued, if
configured, at the end of the test.

IMPORTANT
Disconnect switches for AC sensing and power connections
are necessary to isolate the SPEAR single-phase recloser
control for testing and servicing.
CAUTION
Hazardous voltage . Open CT secondaries can
generate high voltages . Contact with CT pins of the
disconnected cable can cause electric shock and may
result in personal injury . Open recloser contacts and
open disconnect switches before disconnecting
control
cable .

CAUTION
Hazardous voltage . Cable conductors attached to
controls will remain at 53V DC and 120/240V AC
potential while connected to the control . Contact
with any pins at the end of the cable directly or
indirectly connected to a control can result in personal
injury or equipment damage . Disconnect battery and
external power sources in the control then remove
control cable at control end before disconnecting from
recloser
end .

1. Disconnect the 24 V control battery.
2. Disconnect control cable from control.
3. Remove control AC sensing and power connections
from the control.
4. Disconnect any serial communications port connection
5. Disconnect the ground from the control.
6. Carefully transport the control to a suitable service
facility.

Preliminary testing with no AC available
If the SPEAR single-phase recloser control is not in service
and requires energization for preliminary testing, it can be
powered up with battery power only.
1. Open the swing panel and locate the pushbutton switch
recessed inside the control side panel (Figure 39).
2. Momentarily (4-5 seconds) press the switch with a
non-conductive tool (Figure 39). The control will power
up.
3. To power down the SPEAR single-phase recloser
control, unplug the battery (disconnect the black/red
battery connector).
4. Perform a battery charging cycle. Refer to
in the
Battery test and charging procedures
section of these instructions.
IMPORTANT
While the SPEAR single-phase recloser control is powered
in this manner, the control battery is being continuously
discharged. When the battery voltage drops below 21V DC
for 60 seconds, the control will automatically power down.
If the battery is left in a discharged condition, the battery(s)
will sustain permanent irreversible damage. Therefore, a
battery charging cycle should always be performed after this
procedure to bring the battery(s) back up to full charge.
