OVR – Three phase mechanically ganged reclosers
Operator’s quick reference guide for OVR-15, OVR-27 & OVR-38
Product related Safety Notices
The OVR three phase reclosers should be installed within the design limitations as
described on the nameplate and the instructions mentioned in instruction and
maintenance manual. In addition, always follow your company’s safety procedures.
For the safety of the personnel performing maintenance operations on the recloser
or connecting equipment, all components should be electrically disconnected by
means of a visible break and securely grounded.
For detailed information, please refer the instruction manual provided with the
equipment or contact ABB representative.

Disclaimer
This document is to be read along with the instruction manual of the product.
This document has been carefully checked by ABB but deviations cannot be
completely ruled out. In case any errors are detected, the reader is kindly requested
to notify the manufacturer. Other than under explicit contractual commitments, in no
event shall ABB be responsible or liable for any loss or damage resulting from the use
of this document or application of the equipment.
A. Powering-up the recloser
It is assumed that the recloser is already installed as per instructions provided in instruction manual. Ensure the cabinet is properly grounded,
that all MCBs are OFF (lower down) and that the service selector switch is in DISCHARGE position.
1. Open the front, upper & lower auxiliary doors of LV cabinet.

2. Connect external auxiliary power supply to the LV cabinet.
a. Dis-engage the female connector from the male counterpart in the LV
cabinet
b. Connect the external two core auxiliary supply cable to the connector as
indicated in the instruction manual
c. Connect the 2 Pin female connector on the auxiliary supply cable, to its
male counterpart inside the LV cabinet
d. Once engaged, the connection has to be firmly secured by turning &
advancing the circular cap on the female connector over the male
connector
e. Check auxiliary power at 201 - 202 terminal blocks mounted on the back
side of lower auxiliary door.
f. The auxiliary voltage should be as mentioned on rating plate of the LV cabinet.
3. Battery connection
a. While dispatching the equipment from factory, the battery connections
are kept open to reduce internal discharge.
b. Check battery voltage across terminals K20 –J13 and K21 – J13.
c. Voltage in both the cases should be more than 11 V dc. If battery
voltage is less than 11V DC, charge the batteries externally with
external battery charger till voltage across each battery is 12 V dc each
or replace the batteries with new set.
d. After ensuring both battery voltages are more than 11V, check and
firmly connect the 2 pin Green color Male-Female connectors F26 & F27
as per schematic diagram. This will connect the two 12V batteries in
series.
e. Check the voltage across battery terminals to be around 24V
f. Switch ON the MCB: D10-24 MCB for battery
4. Control cable connection to LV cabinet.
a. Insert 24 pin female socket inside the LV cabinet from bottom thru cut
out provided.
b. Fix the floating gland plate (on the cable) to cover the cut out by inserting
4 nos. M6 threaded welded studs on the floating gland plates through the
4 nos. holes provided at the four corners of the cut out and fix with 4nos.
M6 nuts & the M40 nut on the floating gland plate.
c. Connect 24 pin male plug to 24 pin female socket in the LV
5. Put the “Service-Maintenance” rotary switch DS-02 to “Service”
position.
6. Connect communication equipment as applicable.
7. Close both auxiliary doors and switch ON all the MCBs on the
lower auxiliary door.
With the availability of external auxiliary power as per specification,
the LV cabinet will start-up as follows.
a. Relay will startup in approximately 10 Sec.
b. The “Recloser Ready” LED on relay should become green in
approximately 100 Sec.
c. If “Recloser Ready” indication doesn’t turn green after 100
Sec., refer instruction manual for assistance or contact ABB
customer support

D. Handling reclosers during long outages
1. Recloser needs auxiliary power for general application. This power is generally derived from the distribution feeder itself
with the help of control transformer or fed from substation auxiliary source. In case of temporary unavailability of auxiliary
power (few hrs. in a day), the recloser is feed via internal battery bank of the LV cabinet.
2. If battery bank is healthy and in fully charge condition i.e. ≥ 24 Vdc, for the power outage can be of < 24Hrs. without any
special attention required.
3. If power outage is for more than 24 Hrs OR typically > 10 CO operations after power failure, then it is considered as long
power outage requiring special attention of batteries.
4. During long outages, the batteries might get drained to such a level that it might go into deep discharge stage i.e. battery
bank voltage goes below 18 V.
5. In this situation recloser will not be able to recharge the batteries automatically and external charging may be required.
Such situation might also damage batteries permanently and thus required to be replaced.
6. To avoid such situation, in case of power outage more than 24 Hrs. switch OFF the battery MCB D10-24. After the power is
resume, switch ON the battery MCB D10-24
7. If power outage is more than a month, then charge the batteries on regular interval externally to keep ensure the battery
bank voltage more than 21 VDC.
