the meter/distribution system; SPD (test impulse D1) for signal line according to EN
6164321.
All DC cables should be installed to provide runs as short as possible, and
positive and negative cables of the same string or main DC supply should be bundled
together, avoiding the creation of loops in the system.
This requirement for short runs
and bundling includes any associated earth/bonding conductors.
Spark gap devices
are not suitable for use in DC circuits as once conducting, they continue conducting
until the voltage across their terminals is typically less than 30 volts.
Safety criterion
ETL is the standard applied by Electrical Testing Laboratories to the
Digiwatts system to certify that it meets the requirements of the highest
safety criterion of the USA and Canada.
The Digiwatts system has been tested and listed by ETL to meet the
requirements of UL1741 Static Inverters and IEEE 1547 Standard for
Interconnecting Distributed Resources with Electric Power Systems.
The
Digiwatts system is also listed under CSA Std C22.2 No.107.1-01.
