Safety Information
Note: Read the following information before installing and using the
BEAM RST 050.
Your RST 050 is a low power electronic device.
When it is ON, it stores and supplies energy to the attached Beam equipment.
The design of your RST 050 system complies with international safety standards.
Warning: Do not open equipment. There are no user-serviceable
parts inside. Return product to manufacturer for servicing.
If a DC power supply is to be used, its output must comply with the
Safety Extra Low Voltage (SELV) requirements of IEC60950.
All connectors must only be connected to equipment ports which
comply with the Safety Extra Low Voltage (SELV) requirements of
IEC60950.”
Ensure adequate ventilation. Do not use equipment in a gas-tight
chamber.
Do not short circuit output.

RST050 INSTALLATION &USER MANUAL

Welcome
Congratulations on purchasing a Beam Standby Battery RST 050!
This user manual contains all the information you need to use the Beam RST 050
and discover the advantages of Beam Communications and Iridium Network
technology.
What is the RST 050?
The RST 050 is a complementary product to the Remote Satellite Terminal RST100
or RST200 that provides intelligent standby power for telephony, data, geo-location
alert/monitoring, telemetry and advisory function for special applications.
The RST050 is used where the requirement is for full functionality to be provided by
the Beam installation in the absence of normal power.
Figure 1 - The RST 050
The RST050 Backup Battery is a simple product to install using the same mounting
procedure and accessories as other Beam products. DC power from an acceptable
external AC or DC supply is connected to the RST050 and the supplied
interconnection cable is used to connect the Backup battery to the attached terminal.

Getting Started
Connecting the RST050
The RST050 is easily connected to a compatible Beam Satellite Terminal. Follow the
simple step by step directions below:
Step 1
Using the connector cable supplied with the RST050 connect the Battery terminal to
the Beam Satellite terminal as shown in figure 1. The AC power supply from the main
terminal will now be used to supply power to the Battery Backup
Figure 1
Step 2
Using the power supply that was supplied with the Beam Satellite terminal, connect
this to the ‘Power Input” connector of the RST050 Battery Backup as shown in figure
Figure 2

Step 3
In order for the Battery Backup to charge the connector cable must be connected to
at least the battery terminal. Therefore, it is not possible to charge the battery simply
by having the mains power input terminal connected on its own.
The battery cells inside the RST050 are disconnected from the Battery status sensing
circuitry when the 4 pin output cable is not plugged in. Therefore, when the cable is
plugged in, the battery is then linked in circuit ready for use or charging.
Battery Status Indication
The RST050 Battery Back up has been designed with an intelligent charging system
to ensure correct and efficient operation of the battery terminal. The following
information is important to understand how the Battery Back up effectively operates
and in what state the LEDS will appear.
Status LED
If the Battery Status LED is red (with AC power connected), this means that the
battery is flat, and charging is required. The jumper cable MUST be plugged in to the
RST050 for the battery to be charged. Once charged, and if the RST050 is going to
be shelved (not connected to a system until required), it is recommended to un-plug
the 4-pin cable, so that there is no idle current draining the battery.

Power Information
The RST050 Battery Backup power requirements are detailed as follows:
Parameter Specification
Supply Voltage Range 11 to 16v DC
Supply Voltage (Nominal) 12v DC
Supply Current (Maximum) 3A at 12v DC
Supply Current (Average) 0.3A at 12v DC
The RST050 is solar-cell compatible. The solar cell rating must meet or exceed the
power requirements of the supplied plug pack, allowing the RST050 to provide the
same operation during backup as provided by the plug pack installation. The use of
self-regulating cells is recommended.

Battery Maintenance
The RST050 is designed to maximise the life of the batteries used whilst also
maximising service availability to the user in the event of a normal supply interruption.
No special maintenance is required by the user apart from observing the
environmental requirements for the unit.
Battery Charge Modes
The RST050 uses a 3-stage charge algorithm (voltages quoted are at 25Celsius, and
are temperature compensated):
•Under initial charge, the RST050 provides a constant current (boost) charge
until the battery voltage reaches 24.7Vdc.
•The RST050 will then provides constant voltage charging at this 24.7Vdc
voltage, until either:
oThe current the batteries draw drops to C/100 (50mA for the 5Ah cells
used) after which the charger switches to standby-charge-mode, or
oA total charge time of 7.5 hours has lapsed, after which the charger
switches to standby-charge-mode.
In standby-charge-mode the charge voltage drops to approximately 22Vdc and the
batteries are left in this charge mode, continually topping up charge.
