General
Powerfinn Robust series chargers use modern switching technology. The intelligent
microcontroller extends the battery life by supervising the charging process. The
charger is compact, silent and meets the EU safety and EMC requirements.
For hardware specification, see separate document "Specification".
For detailed technical information, see "Robust technical handbook".
This document applies to software versions 5 and later, upto version 9, if not
otherwise stated.
Information is subject to change without notice.
Guarantee
The charger has a guarantee of two years from the date of purchase. Guarantee
covers manufacturing and component failures and is valid only if the equipment is
installed and used according to the instructions in this manual.
Keep the receipt as evidence of the date of purchase.

Safety Instructions
In addition to the safety measures mentioned in chapter ‘Operations’, the following
personal precautions should be taken whenever charging batteries.
1. For emergency situations ensure in advance that help is available in time of need.
2. Batteries contain acid that is harmful to the eyes, skin and clothes. Always wear
overalls and safety goggles. Never touch the eyes with unwashed hands after
handling batteries.
3. Ensure that a working, fresh water tap is available. If acid gets into the eyes or on
the skin, immediately rinse the area with plenty of water for several minutes. If
visible injury occurs, contact a physician immediately. In case of eye injuries,
always contact a physician.
4. The charging process generates explosive hydrogen gas. Do not smoke or otherwise
bring burning or sparking matter to the vicinity of the battery when it is being
charged.
5. If a short circuit occurs, the battery may explode or the item causing the short
circuit may melt. Keep the work area clear from tools and debris. Remove jewelry,
watches, etcetera before working with the battery.
6. The power cord should be unplugged and the battery must be disconnected from
the charger in case the equipment is left unused for a longer period of time.
7. The charger must be located away from heat sources like radiators and heat
registers.
8. This device is not meant to be used by children or people whose physical, sensory or
mental attributes or lack of experience and knowledge prevent them from using the
device safely unless a person responsible for their safety supervises them or has
instructed them how to use the device.

Installation
The charger should be installed indoors in a low humid area.
These instructions apply to all types of chargers produced at the time of writing; types
prefixed with "R" and "NSR".
The following points must be respected when installing the charger.
1. In fixed installation the operation temperature range is -35°C to +55°. Higher than
+40° ambient temperature will limit the output power.
2. The charging process generates explosive hydrogen gas. Install the charger as far
away from the battery as possible to prevent hydrogen gases from entering the
charger. Keep the space well ventilated. Never use an open flame or equipment
that produces sparks close to the battery or charger.
3. For unplugging the unit, make sure the wall socket is located in an easy access area.
Wall socket must provide protective earth terminal.
4. Install on concrete or other non-combustible surface only.
5. To ensure sufficient cooling, do not cover the charger. Leave a free space of at least
10 cm around all sides. For passive cooled model, leave 50 cm free space above
and below the charger. Passive cooled model is to be installed vertically, with
cable entry downward. Fan cooled model can be installed also horizontally.
Chargers are manufactured in various protection classes. IP class is usually marked
on the product label. If IP class is not marked, or it is IP20, charger should be
installed into a dry environment. To maintain protection class, install IP54 models
vertically, with cable entry downward. IP65 and IP66 models can be installed with
free orientation.

Charger slides to mounting plate from above and can be secured using screws.
For fan cooled models, mounting plate is of different size but of similar type:

Charging configuration
The charger voltage, charging algorithm and configured battery capacity should
correspond to the battery parameters. Attempting to charge a battery with wrong
charging configuration may result in considerable damage. For example, too large
configured battery capacity results in excessive charging current. Do not attempt to
charge non-rechargeable batteries.
When installing the charger, make sure that incompatible charger setups and batteries
cannot be connected together. Connector arrangement is a reliable method. Matching
battery type can be indicated by a label attached to the charger.
Voltage and number of cells
Chargers are available for a variety of battery voltages. Robust series chargers can
charge lead-acid batteries that have number of cells as follows:
charger type/ nominal voltage
number of cells in
the battery
nominal voltage of
the battery
1100/24, 2300/24, 3000/24
12

1100/36, 2300/36

1100/48, 2300/48, 3000/48

48
Also batteries with non-listed number of cells can be charged, if charger is properly
configured. For more information on this, see Robust series technical handbook.
Algorithm
Robust series chargers can charge freely ventilated and sealed lead-acid batteries.
Verify compatibility of the algorithm and the battery with your battery
manufacturer. For descriptions of algorithms, see Robust technical handbook,
chapter "Algorithms".
For step-by-step instructions on how to select an algorithm using the front panel,
see Robust technical handbook, chapter “Editing charging configuration”.
Capacity
Robust series chargers can charge lead-acid batteries that have nominal capacity
between 50 ... 2000 Ah.
For step-by-step instructions on configuring the battery capacity using the front panel,
see Robust technical handbook, chapter “Editing charging configuration”.

Operation
Read these operating instructions carefully before using the charger for the first time.
Also read the chapter "Safety instructions" thoroughly. It must be ensured that
children do not play with the device.
To charge a battery with ”Robust" series charger, follow these instructions:
The factory default setting is
- Algorithm LK10-06 freely ventilated lead-acid
- Battery capacity 50 Ah
- Number of cells is set according to nominal voltage of the charger. For example
nominally 24 V charger is set to 12 cells.
To change the settings, see Robust technical handbook, chapter “Editing charging
configuration".
1. Ensure that the charger is unplugged and that the installation environment meets
the conditions described in chapter "Installation".
Warning: Explosive gases. Prevent flames and sparks. Provide adequate
ventilation during charging.
If charger has been stored in condensing or freezing temperature for an extended
period, allow it to warm up and dry for 12 h before operating.
2. Connect the charger cables to the battery terminals: the positive (+) cable to the
positive (+) terminal and the negative (–) cable to the negative (–) terminal. The
positive cable is red colored. The negative cable is black or blue.
Warning: Connection with wrong polarity might cause personal injuries and
damage the charger and battery.
3. Turn the power on by plugging the power cord in a mains outlet with protective
earth.
4. Charging starts automatically.
STOP
Pressing STOP will PAUSE charging. Pressing STOP again resumes charging.
F1 and F2
F1 and F2 buttons can be assigned various functionality. By default no function is
assigned, so pressing buttons during charging has no effect. Buttons are used when
settings are changed. See chapter “Editing charging configuration” in Robust
technical handbook.
5. To avoid sparking in output cables, press STOP button before disconnecting battery.
