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 power module carefully:
•
Use safety shoes with a steel toe cap and protective gloves.
•
Use caution when you move the 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.
•
Do not handle the power module alone, have at least two persons handling the
power module.
•
Keep the spare power module always in the transport package when moving and
storing, and remove it from the package just before replacement work.
•
Obey the instructions in all related PVS980 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 doors 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 DC input and AC output circuits are isolated from the enclosure and the
ground as standard. There is PV system grounding, but floating system is an
option, if inverter grounding is required by Section 250 of the National Electrical
Code, ANSI/NFPA 70, the inverter must be ordered with the grounding. 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.
