1.9 Proper use
The DC1 variable frequency drives are electrical devices for controlling
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 DC1 variable frequency drives are not domestic appliances. They are
designed only for industrial use as system components.
If the variable speed starter 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 Machinery Safety
Directive 2006/42/EC (e.g., by complying with EN 60204). The user of the
equipment is responsible for ensuring that the machine use complies with
the relevant EU Directives.
The CE markings on DC1 variable frequency drives confirm that the devices
meet the
requirements
set forth in the European Union’s Low Voltage and
EMC Directives (Directives 2014/35/EU, 2014/30/EU and ROHS 2011/65/EU)
when used in their typical drive configuration.
In the described system configurations,
DC1
variable frequency drives are
suitable for use in public and non-public networks.
A connection of a DC1 variable frequency drive to IT networks (networks
without reference to earth potential) is permissible only to a limited extent,
since the device’s built-in filter capacitors connect the network with the earth
potential (enclosure).
In unearthed networks, this can result in hazardous situations or damage to
the device (insulation monitoring is required!).
￫
To the output (terminals U, V, W) of the DC1 variable frequency
drive you must not:
• connect a voltage or capacitive loads (e.g. phase
compensation capacitors),
• Connect 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 use will be considered to be an improper use of the
device.
