Only qualified personnel should work on the equipment, warning signs must be kept legible, the system must be grounded, and the dc‑link capacitor can stay charged for minutes after power removal, so the unit should not be opened until five minutes after power is off.
The inverters support remote control via an RS485 serial link using the USS protocol, and up to 31 inverters can be networked together.
The manual specifies a recommended mains fuse of 10 A for the 250 W MICRO MASTER inverter.
The inverters can handle an overload of 150 % of rated current for up to 60 seconds.
