WARNING! An electric shock can be fatal. Inadequately sized electrical compo-
nents 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 appli-
cable to the installation site.
- For installations in Canada, the installations must be done in accordance with
applicable Canadian standards.
- Use minimum AWG 12, min. 167 °F (75 °C), copper wire for the AC connec-
tion of the FRONIUS IG 2000, 3000 and 2500-LV.
- Use minimum AWG 10, min. 167 °F (75 °C), copper wire for the AC connec-
tion of the FRONIUS IG 4000, 5100 and 4500-LV.
- Use minimum AWG 14, min. 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.
WARNING! An electric shock can be fatal. Danger from grid voltage and DC volt-
age from solar modules.
The connection area should only be opened by a licensed electrician.
Never work with live wires! Prior to all connection work, make sure that the AC
and DC wires are not charged.
CAUTION! Danger of damaging the inverter due to an overload of the grid neutral
conductor.
-
Do not connect 2-phase and 3-phase devices to one phase
- Never operate multiphase devices in one phase
CAUTION! Danger of damaging the inverter from improperly connected termi-
nals. Improperly connected 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.
