Remove The Control From Service; Preliminary Testing With No Ac Available - Eaton COOPER POWER Series M Installation And Operation Instructions

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.

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

1. Disconnect the 24 V control battery.
2. Disconnect control cable from control.

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.
While the SPEAR single-phase recloser control is powered
in this manner, the control battery is being continuously
T312 .3
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.
