Buffer power supply system for PoE switches SWBH-60 is designed for uninterrupted power supply of PoE
switches with 52 V DC. It was designed based on switching power supply module with attached DC / DC converter with
high energy efficiency, placed in in ABS (IP44) enclosure.DC/DC converter used to increase voltage allows to reduce
costs of system by limiting batteries to 1 pc. Enclosure has a place for 7Ah / 12V (SLA) battery. Device is equipped with
removable universal mounting plate, which allows to mount PoE switches with dimensions up to 210x128x35 (WxHxD)
[mm]. For example Pulsar’s models: S64WP, SG64WP, SFG64F1WP, SFG64WP, ISFG42, ISFG64.

2. Installation.
2.1 Requirements.
Device is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required
for a given country) with ~230 V mains supply. Unit should be mounted in confined spaces with normal relative humidity
(RH=90% maximum, without condensing) and temperature from -10°C to +40°C. Device must be mounted in a vertical
position with cable glands facing downwards. Mounting in any other position is not permitted. Ensure free convective
airflow around enclosure.
As power supply is designed for a continuous operation and is not equipped with a power-switch, therefore, an
appropriate overload protection in power supply circuit should be provided. Moreover, the user shall be informed about
the method of unplugging (most frequently through separating and assigning an appropriate fuse in the fuse-box).
The electrical system shall follow valid standards and regulations.

2.2 Installation procedure.
CAUTION!
Before installation, cut off voltage in 230 V power-supply circuit. To switch power off, use an
external switch, in which distance between contacts of all poles in disconnection state is not
less than 3mm.
It is required to install in the supply circuits, in addition to power supply, circuit breaker with 6 A
nominal current.
1. Remove mounting plate with mounted power supply
2. Mount device and feed connection wires through glands and filler inserts. Then tighten the glands (unused ones
should be blanked off).
3. Install mounting plate with mounted power supply
4. Connect power cables (~230 V) to L-N clips of PSU. Connect ground wire to clip marked by earth symbol .
Use a three-core cable (with a yellow and green protection wire) to make connection ). Lead the power cables
to the relevant terminals of the power supply via an isolation conduit. Wires should be deisolated to a length of
7mm.
The shock protection circuit shall be done with a particular care: the yellow and green wire
coat of the power cable should be connected to the terminal marked with the grounding symbol on
the PSU enclosure. Operation of the PSU without the properly made and fully operational shock
protection circuit is UNACCEPTABLE! It can cause damage to the equipment or an electric shock.
5. Connect battery in correct polarity.
6. Lock battery with attached strap.
7. Screw switch to mounting plate and connect it using wire with DC 2.1/5.5 plug.
8. Switch on ~230 V supply.
9. After installing and checking proper working, the enclosure can be closed (ensure that cover fits evenly over its
entire surface).

3. Operating status indication.
Moreover, PSU is equipped with LED indicating presence of voltage at PSU output, located on PCB of PSU
module.
4. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the power
supply network. The PSU does not require performing any specific maintenance measures, however, in the case of
significant dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse replacement,
use a replacement of the same parameters.
WEEE LABEL
CAUTION! Waste electrical and electronic equipment must not be disposed of with normal household waste.
According to the European Union WEEE Directive, waste electrical and electronic equipment should be disposed of
separately from normal household waste.
