Grounding safety rules for electricians
• Comply with all relevant electrical safety regulations of the installation country or
region.
• Always connect protective earth (PE) to the inverter and associated equipment to
ensure personal safety and electromagnetic compatibility.
• Ensure that grounding connections are sized to meet safety regulations.
• Chaining is not allowed. In multi-inverter installations, connect each inverter to the
protective earth (PE) of the distribution board separately.
• Never ground the DC+ or DC- live conductors.
Notes:
• PVS300 is a transformerless inverter; the DC side and AC grid are not
galvanically separated. Therefore the inverter must not be used with solar
modules which require DC+ or DC- conductor grounding.
• The inverter has two protective earth terminals which are:
- a screw terminal connection inside the AC connector
- a PE screw for a cable lug connection to the right side of the AC connector.
• As the touch current of the inverter may be higher than 3.5 mA AC or 10 mA DC in
case of failure of the protective earthing conductor, a fixed protective earth
connection is required. See
Selecting the power cables on page 37 .

General safety
WARNING! Ignoring the following instructions can cause injury or death, or
damage to the equipment.
• The inverter is not field repairable. Never attempt to repair a malfunctioning unit;
contact your supplier, local ABB representative or Authorized Service Center for a
replacement.
• Protect the inverter so that dust from drilling cannot enter it during installation.
Electrically conductive dust inside the unit may cause damage or malfunction.
• The inverter is heavy and should be lifted by two persons wearing appropriate
personal protective equipment.
• Choose an installation location where audible noise from the inverter(s) is least
likely to disturb people.
• Do not obstruct the inverter cooling air inlets and outlets. The mounting plate is
designed to maintain a small gap between the inverter body and the wall.
Safe start-up and operation
These warnings are intended for everyone involved in planning the operation, start up
or operation of the inverter.
