Safety
WARNING! Incorrect operation and work performed incorrectly can cause serious injury and damage to
property. Only qualified staff are authorized to install your inverter and only within the scope of the res-
pective technical regulations. Do not start operation or carry out maintenance work until you have read
the "Safety Instructions" chapter.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modu-
les that are exposed to light.
- Never work with live wires! Prior to all connection work, make sure that the AC and DC wires are
not charged.
- Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
WARNING! An electric shock can be fatal. Danger of electric shock due to incorrect or insufficient solar
module grounding.
- The inverter is designed for negative solar module grounding as standard. Solar module grounding
is carried out via a GFDI fuse in the inverter.
- When operating ungrounded solar modules, remove the GFDI fuse before starting operation and
adjust the inverter grounding settings accordingly.
- When operating positively grounded solar modules, the solar modules are not grounded via the fuse
in the inverter, but rather must be grounded externally to the inverter.
WARNING! An electric shock can be fatal. Normally grounded conductors may be ungrounded and
energized when a ground fault is indicated. The ground fault has to be repaired before operation is re-
sumed.
WARNING! An electric shock can be fatal. Inadequately sized electrical components can cause serious
injuries to persons and damage to (or loss of) property.
- All electrical installations must be carried out in accordance with the National Electrical Code, ANSI/
NFPA 70, and any other codes and regulations applicable to the installation site.
- For installations in Canada, the installations must be done in accordance with applicable Canadian
standards.
- Use 167 °F (75 °C), copper wire for all grounding wires (see NEC table 250.122).
- Voltage drop and other considerations may dictate larger size wires be used.
- Use only solid or stranded wire. Do not use fine stranded wire.
An electric shock can be fatal. Danger of DC voltage from solar modules. When solar modules are groun-
ded, the inverter's insulation monitoring is deactivated.
- Ensure that grounded solar modules are double insulated according to Protection Class II.
- Attach corresponding safety labels to the photovoltaic system where they can be seen easily.
- Set the inverter so that an error message is displayed if the fuse trips.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar modu-
les that are exposed to light.
- The DC main switch is used only to switch off power to the power stage set. When the DC main
switch is turned off, the connection area is still energized.
- All maintenance and service work should only be carried out when the power stage set has been
disconnected from the connection area.
- The separate power stage set area should only be disconnected from the connection area after first
being disconnected from the grid power.
- Maintenance and service work on the inverter power stage set should only be carried out by Froni-
us-trained personnel.
WARNING! An electric shock can be fatal. Danger from residual voltage from capacitors. You must wait
until the capacitors have discharged. Discharge takes 3 minutes.
WARNING! An inadequate grounding conductor connection can cause serious injuries to persons and
damage to (or loss of) property. The housing screws provide an adequate protective conductor connec-
tion for grounding the housing and should not be replaced under any circumstances by other screws that
do not provide a proper protective conductor connection!
