1.11 Proper use
The DB1 series of variable frequency drives are electrical devices for control-
ling variable-speed drives with three-phase motors. They are designed for
installation in machines or for use in combination with other components
within a machine or system.
The DB1 variable frequency drives are not domestic appliances. They are
designed only for industrial use as system components.
If the variable frequency drive is installed in a machine, it is prohibited to
place it into operation until it has been determined that the corresponding
machine meets the safety and protection requirements set forth in Machi-
nery Safety Directive 2006/42/EC (e.g., by complying with EN 60204).
The user is responsible for ensuring the machine's usage is in compliance
with EC Directives.
The CE labels applied to the DB1 series of variable frequency drives confirm
that the devices comply with the Low Voltage Directive (2014/35/EU), the
Electromagnetic Compatibility (EMC) Directive (2014/30/EU), and the RoHS
Directive (2011/65/EU) when the typical drive configuration is applied.
In the described system configurations, the DB1 series of variable frequency
drives are suitable for use in public and non-public systems.
Connection of a DB1 variable frequency drive to IT networks (networks wit-
hout reference to ground potential) is permissible only to a limited extent,
since the device’s built-in filter capacitors connect the mains to the ground
potential (housing).
In ungrounded networks, this can result in hazardous situations or damage to
the device (insulation monitoring is required!).
￫
You must not connect any voltage or capacitive loads to the
output (terminals U, V, W)
•
connect a voltage or capacitive loads (e.g. phase compensa-
tion capacitors),
•
nor multiple variable frequency drives in parallel,
•
make a direct connection to the input (bypass).
￫
Always observe the technical data and connection conditions!
For additional information, refer to the equipment nameplate or
label at the variable frequency drive and the documentation.
Any other usage constitutes improper use.
