14 Safety instructions
General safety
These instructions are for all personnel who install the inverter and do 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 metal toe cap and protective gloves.
• Use caution when you move an inverter power module. Do not tilt the module. The
module is heavy. It can topple over if you handle it carelessly.
• Obey the instructions in the PVS800-57B Commissioning and maintenance
manual (3AXD50000048331 [EN]).
• Be aware of the cooling fan blades. The fans can operate for a few seconds after you
disconnect the electrical supply.
• Be aware of hot surfaces. Some parts in the inverter cabinet 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 doors of the inverter during a rain or when sand or dust can blow into
the unit. Water or sand in the inverter can cause damage in the unit.
• Do not secure the cabinet by electric welding.
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.).
