2Markings & Symbols
1. To identify the location where the operator's manual is stored or to identify
information that relates to the operating instructions. To indicate that the
operating instructions should be considered when operating the device or
control close to where the symbol is placed.
2. To identify equipment that has risk of electric shock.
3. To identify energy storage timed discharge –that is the time required after
disconnecting the unit from all energy sources and turning off the battery
circuit breaker until the capacitor energy storage in the unit is less than
48VDC.
4. To indicate that caution is necessary when operating the device or control
close to where the symbol is placed, or to indicate that the current situation
needs operator awareness or operator action to avoid undesirable
consequences.
5. To identify any terminal which is intended for connection to an external
conductor for protection against electric shock in case of a fault, or the
terminal of a protective earth (ground) electrode.

Disposal
Electronic Device: Do not throw away
Proper disposal of batteries is required. Refer
to your local codes for disposal requirements.
Recommended Charge
instructions
Charging is only allowed using the provided Elektrobank 14
system, do not try charging with a different charger
3External RCD Requirements
This product requires an external RCD Type A, 30mA to be installed on every
subcircuit powered by the backup port

Version 5.0
Page 7 of 33
4Warnings
1. When the photovoltaic (PV) array is exposed to light, it supplies a d.c. voltage to the PCE.
2. External RCD Type A 30mA is required on backup port (if connected).
3. An RCD is not permitted on the grid/supply side of the device as it is a multi-mode inverter and
an RCD would allow disconnection of the neutral MEN connection for backup loads.
4. It is required that any PV modules connected to the device have an IEC 61730 Class A rating.
5. If the equipment is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
6. Only a qualified professional (e.g. service person) may install the Elektrobank 14.
7. Servicing or replacement of batteries shall not be conducted in the field by anyone other than
Empower personnel. Initial installation is allowed as per this manual.
8. CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
9. CAUTION: Do not open or damage batteries. Released electrolyte is harmful to the skin and eyes.
It may be toxic.
10. CAUTION: The backup port should not be used for devices providing safety or health critical
devices
11. SAFE HANDLING: Elektrobank 14 and battery modules are heavy. To minimise risk when handling
the goods, lift and transport the goods carefully and wear personal protective equipment such as
steel-toe boots and gloves. Use of lifting equipment is recommended
12. SAFE TRANSPORT: Always transport the goods to site in the original packaging. During unpacking,
inspect the goods for damage such as large dents or deep scratches, which may indicate the unit
was dropped. Do not use Elektrobank 14 if it is defective or appears damaged in any way,
internal or external. Contact your supplier for further advice.
13. Touch current is above the limit. Ensure 10mm2 copper PE cable is used for connection to PE
terminal.
14. The Elektrobank 14 cannot be used in multiple inverter combinations as per section 5 of the
AS/NZS 4777.2:2020.

3. Only Copper wire is suitable for use
4. Make sure all grid/earth cabling is rated for outdoor use as per local standards. Recommend
running all external cabling in conduit. Connect cable as in the below image, live (L), neutral (N)
and earth (earth symbol) to terminal block as marked
5. Ensure the main >10mm2minimum earth wire is longer than the live and neutral wire so that if
the cable pulls out the earth wire is the last to be disconnected, It shall be connected to one of
the Grid connector Earth points. The spare Earth port can be used for a second earth that may be
present in the twin core and earth cable used.
6. The wires shall be stripped to 18mm and the connections are push fit spring connections.
a. Insert, push until no copper can be seen and then do an approximately 1kg pull test and
confirm no copper can be seen.
7. At this stage confirm all grid cables, especially earth is well connected mechanically and confirm
with multimeter that the enclosure has continuity to earth.
8. Ensure gland is tightened to IP66 (note –do not replace gland that is provided with the unit)
