Manual Energy Storage Inverter ESI-S
8.2 Step 1: Visual and installation check
WARNING: Make sure that the inverter supply is isolated during the visual and
installation check. For safety reasons, this must be done upstream of the inverters
and before removing the right protective cover. In multi-unit inverters, ensure that all
units are disconnected from the supply.
In order to perform a successful installation and commissioning, only the right side of
the protective cover of the inverter needs to be removed.
WARNING: The left side of the protective cover should not be removed because there
are live parts underneath. When the right side of the protective cover is removed, open
the auxiliary power fuse holder. Failure to adhere to these guidelines may result in
lethal electric shock and/or inverter damage.
WARNING: Connect the correct polarity of the battery to the ESI. Wrong polarity of
battery may result in severe damage to the inverter and/or battery.
WARNING: Make sure that the inverter is installed at a location where no
conductive dust is present. Conductive dust when distributed in the inverter panel
may lead to equipment failure.
−
Check that the mechanical and electrical installation fulfils the requirements
described in
Chapter 5
and
of this manual.
−
Pay attention to the ambient temperature noting the inverter cooling
requirements.
−
Check visually the condition of the inverter (e.g. for transportation damage).
−
Remove the anti-corrosion capsules which are affixed at the inside of the inverter,
at the bottom (next to the fan and IGBT assembly).
−
Check the tightness of all connections including power cable connections section
and tightness, CT connections, digital I/O connections on the ESI-Manager and
the control board connections inside the inverter.
−
Ensure that the feeding cable protection devices are rated appropriately (see
8.3 Step 2: Setting the address of each unit in a multi-unit inverter
and terminate the CAN bus
Each inverter is defined by an inverter address. This address is by default set to 1.
