Warnings
Only authorized personnel trained in the setup, installation, commissioning, and
operation of the product may work on the product and plant.
♦
SED2 variable speed drives operate at high voltages.
♦
Operation of electrical equipment inevitably involves the use of dangerous voltages
in some components.
♦
Emergency stop facilities in accordance with EN 60204 IEC 204 (VDE 0113) must
remain operative in all operating modes of the control equipment. Resetting the
emergency stop facility must not result in an uncontrolled or undefined restart.
♦
In cases where faults in the control equipment could cause significant equipment
damage or severe physical injury (e.g. potentially dangerous short circuits), take
additional external precautions or provide facilities to ensure or enforce safe
operation even in the event of a short circuit (e.g. independent limit switches,
mechanical interlocks, etc.).
♦
Certain parameter settings may cause the variable speed drive to restart
automatically after a power failure.
For reliable motor overload protection, the motor parameters must be configured
accurately.
The equipment incorporates internal motor overload protection in accordance with
UL508C, section 42. Refer to P0610; I
protection can also be provided via an external PTC temperature sensor (disabled by
default, P0601).
The equipment is suitable for use in a circuit delivering max. 10,000 symmetrical amps
(rms), and is designed for a maximum voltage of 230V/460V/575V when protected by a
type H or K fuse.
Do not use the variable speed drive as an "emergency stop facility".
