10 Safety instructions

General safety
These instructions are for all personnel who install the inverter and/or perform
maintenance work on it.
WARNING! Obey these instructions to prevent injury or death, or damage to the
equipment.
•
Move the inverter power module carefully:
•
Use safety shoes with a steel toe cap and protective gloves.
•
Use caution when you move the inverter power module. Do not tilt the module.
The module is heavy. Careless handling of the power module may cause it to
topple over resulting in bodily injury and/or damage to the equipment.
•
Obey the instructions in all related manuals
•
Be aware of the cooling fan blades. The fans can operate for a few seconds after you
disconnect the electrical supply. Do not stick fingers or other objects into the fans.
•
Be aware of hot surfaces. Some parts in the inverter cabinet, such as the heat
exchangers are hot after you disconnect the electrical supply.
•
Make sure that the debris from the installation work does not go into the inverter.
Electrically conductive debris in the unit can cause damage.
•
Do not open the panels of the inverter when it is raining, or when sand or dust can
blow into the unit. Water or sand in the inverter can cause damage in the unit.
Note for UL installations:
The AC input and AC output circuits are isolated from the enclosure and the
ground as standard. There is no Photovoltaic System Grounding. If system
grounding is required by Section 250 of the National Electrical Code,
ANSI/NFPA 70, the system installer must install it. The installation must agree with
the requirements of Sections 690.41 through 690.47 of the National Electrical
Code, ANSI/NFPA 70.
Printed circuit boards
WARNING! Use a grounding wristband when you handle the printed circuit
boards. Do not touch the boards unnecessarily. The boards have components
that are sensitive to electrostatic discharge.
Fiber optic cables
WARNING! Obey these instructions to prevent injury or death, or damage to the
equipment.
•
Handle the fiber optic cables with care.
•
When you disconnect the cables, hold the connector, not the cable.
•
Do not touch the ends of the fibers with bare hands as the ends are extremely
sensitive to dirt.
•
Do not bend the fiber optic cables too tightly. The minimum permitted bend radius is
35 mm (1.4 in).
