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 
(Figure 38).
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 Battery 
charging 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.
