6.8 Demand response modes (DRMs)
Inverters of this series feature the demand response modes and use a 16-pin socket as
the DRMs connector.
6.8.1 16-Pin socket pin assignment
DRMs application description
Ø Applicable to AS/NZS4777.2:2015 or Commission Regulation
(EU) 2016/631.
Ø DRM0, DRM5, DRM6, DRM7, DRM8 are available.
Damage to the inverter due to moisture and dust penetration
Ø Make sure the cable glands have been tightened firmly.
Ø If the cable glands are not mounted properly, the inverter can be
destroyed due to moisture and dust penetration. In this case, all
warranties shall be void.
Excessive voltage can damage the inverter!
External voltage connected to the DRM PORT should not exceed +5V.
Information
CAUTION
WARNING
6.8.2 Method of asserting demand response modes
Socket asserted by
shorting pins
Operate the disconnection device.
Do not generate at more than 50% of rated power.
Do not generate at more than 75% of rated power
and sink reactive power if capable.
Increase power generation (subject to constraints
from other active DRMs).
