Warnings
Only authorized personnel trained in the setup, installation, commissioning and operation of the product may work
on the product and plant.
Danger
♦ SED2 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 60 204 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 end switches, mechanical
interlocks, etc.)
♦ Certain parameter settings may cause the VSD to restart automatically after a power
failure
Caution
For reliable motor overload protection, the motor parameters must be accurately
configured.
The equipment incorporates internal motor overload protection in accordance with UL508C,
section 42. Refer to P0610; I
2
t is the default for ON. Motor overload 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 AC 230 V / 460 V / 575 V when protected
by a type H or K fuse.
Do not use the VSD as an “emergency stop facility" (see EN 60 204, 9.2.5.4).
