Safety EN-US
WARNING! Incorrect operation and incorrectly performed work can cause serious injury and damage
to property. Only qualified staff are authorized to commission the inverter and only within the scope of
the respective technical regulations. Do not commission the inverter or carry out maintenance work un -
til you have read the safety rules.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modu -
les that are exposed to light.
- Prior to all connection work, disconnect the AC and DC supply to the inverter.
- Only an authorized electrician is permitted to connect this inverter to the public grid.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC voltage from solar modu -
les.
- 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 Fro -
nius-trained service technicians.
WARNING! An electric shock can be fatal. Inadequately sized electrical components can cause seri -
ous injury and damage to property.
- All electrical connections must be made in accordance with the National Electrical Code, ANSI/
NFPA 70, and any other regulations applicable to the installation site.
- Installations in Canada must be carried out in accordance with applicable Canadian standards.
- Use min. 194 °F (90 °C) copper wire for all grounding wires (see NEC table 250.122).
- For all AC/DC wires, use a minimum of 167 °F (75 °C).
- Voltage drop and other considerations may mean larger cable cross sections need to be used.
- Use only solid or stranded wire. Do not use fine stranded wire.
WARNING! An electric shock can be fatal. Danger of residual voltage from capacitors. Wait until the
capacitors have discharged. Discharge takes 5 minutes.
WARNING! An inadequate ground conductor connection can cause serious injury and damage to pro -
perty. The housing screws provide an adequate ground conductor connection for grounding the hou -
sing and should not be replaced under any circumstances by other screws that do not provide a reliable
ground conductor connection.
WARNING! Work performed incorrectly can cause serious injury and damage. The surge protection
device should only be installed and connected by licensed electricians. Observe the safety rules! Prior
to all installation and connection work, disconnect the AC and DC supply to the inverter.
CAUTION! The inverter can be damaged by soiling or water on the terminals and contacts in the con -
nection area.
- When drilling, make sure that terminals and contacts in the connection area do not become soiled
or wet.
- The wall bracket without the power stage set does not possess the same degree of protection as
the complete inverter and, therefore, should not be attached without a power stage set.
Protect the wall bracket from soiling and moisture during installation.
CAUTION! Danger of damaging the inverter due to improperly connected terminals. Improperly con -
nected terminals can cause thermal damage to the inverter and may cause a fire. When connecting the
AC and DC cables, make sure that all terminals are tightened securely using the proper torque.
