CHAPTER 3 - Installation of the drive
3.5 Reference to safety standards
3.5.1 Installation operations
WARNING !: Qualified personnel only are allowed to operate on the installation,
in trouble shooting and, in general, for any type of intervention on the drive.
This personnel must have adequate documentation supplied by ABB Servomotors, this
manual in particular.
It is forbidden for non qualified personnel to intervene on the terminal board of the convertor
or open the connection box of the servomotor.
3.5.2 Residual voltage
WARNING !: In the BHL-D convertor capacitors of great capacity are present,
which, for functional reasons, cannot always be discharged in a time shorter than
5 seconds, after the interruption of supply.
It is forbidden to touch inside the BHL-D convertor before at least three minutes have
passed after the interruption of supply. Potentially lethal voltages may be present on
the dc intermediate circuit and on the associated circuits!
A proper warning, placed visibly, must be present on the BHL-D convertor to warn about this
danger, according to what established in EN 60204-1 § 6.2.3.
3.5.3 Supply sectioning device
WARNING !: Since the BHL-D convertor is prepared to be put in an electric
cabin, possibly also containing other apparatus, the supply sectioning device
manually controlled, required by EN 60204-2 § 5.3.1, can be the one common
to the whole electric cabin and must - in any case - be inserted care of the
manufacturer of the machine.
3.5.4 Stop function
WARNING !: Stop functions, as prescribed in EN 60204-1 § 9.2.2, in particular
0 category stop, must be realized by the manufacturer of the machine,
because they are related to the logic of the machine, which obviously differs
according to the type of machine driven, following the instructions contained in
the present manual.
3.5.5 Emergency stop
WARNING !: Also emergency stop, according to EN 60204-1 § 9.2.5.4, must be
foreseen following the specific characteristics of the machine driven. Therefore it
must be realized by the manufacturer of the machine.
