UPDATED bullet points (page 11): Safety in installation and maintenance
Precautions before electrical work
These precautions are for all personnel who do work on the inverter, its input and output cables, the
transformer or the photovoltaic generator.
The notice concerns the following PVS800-57 Hardware
Manuals:
Code: 3AXD50000217960 Rev A
Valid: from 21.12.2017 until the release of Rev J of the
hardware manual
Contents: the main new features and changes which are not
yet updated to the manual.
The headings in this update notice refer to the modified
subsections in the original English manual. Each heading also
include a page number and a classifier NEW, CHANGED, or
DELETED. The page number refers to page number in the
original English manual. The classifier describes the type of
the modification.
WARNING! Obey these instructions to prevent injury or death, or damage to the
equipment. You must be a qualified electrician to do installation and service work. Do
these steps before you do installation or maintenance work on the inverter.
□ 1. Clearly identify the work location.
□ 2. Disconnect all possible voltage sources.
• Open the AC main switch-disconnector (Q1), the DC main switch (Q2) and the
auxiliary supply disconnector (Q10) of the inverter.
• Open the disconnector of the transformer as the AC main switch-disconnector
(Q1) does not remove the voltage from the AC busbars of the inverter.
• Open the DC circuit breakers of the solar array junction boxes. The DC main
switch (Q2) does not isolate the DC input fuses, cables or terminals from the DC
voltage supplied by the photovoltaic generator.
• Make sure that reconnection is not possible. Lock the disconnectors to open
position and attach a warning notice to them.
• After you have disconnected the inverter, always wait for 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
