Note:
for safety reasons, ZCS Spa and/or its partners may not carry out any technical repairs or
maintenance work, or move the inverter or battery pack from and to the ground if they are installed at a
height of more than 180 cm from the ground.
Inverters and/or battery packs installed at higher heights must be moved to the ground before they can be
repaired or serviced.

Electrical connections
•
Carefully assess the risks deriving from electric shocks and chemical hazards!
•
Use a multi-metre to check the DC polarity of the battery and cables before connecting the power supply
between the batteries and inverter.
NOTE: an inverted polarity connection may cause irreparable damage to the inverter and batteries.
•
In order to enable safe connection and disconnection of the inverter during installation and maintenance,
a 100A DC disconnecting device must be installed between the 3000SP inverter and battery. This
operation is not necessary if lithium batteries with BMS are used as they have an internal disconnecting
system, such as Pylontech US2000B and US2000PLUS batteries supplied with the Azzurro ZCS storage
inverter.
Note: the Pylontech US2000B and US2000PLUS batteries, as well as the Tawaki Maui 4 kWh and Weco
HeSU 4K4 batteries do not require a disconnecting device for connecting to the storage inverter. The
Cable kit, which includes crimped power cables for connecting the Pylontech batteries to the 3000SP
storage inverter, is supplied separately. It is recommended to ensure that your storage kit is equipped
with this accessory. In the case of Tawaki and Weco batteries, the connection kit is already inside the
package.
•
A 25 AC disconnecting device (circuit breaker) must be installed between the 3000SP inverter and the
power grid. It is also recommended to use a differential with a trip threshold of 30 mA between the
3000SP inverter and power grid.
•
For safety and proper functioning of the system, it is important to use a cable of the appropriate type and
