Rockwell Automation 161 SERIES A - Manual (Page 6)

Bulletin 161
iv
ATTENTION
•
To prevent any injuries or damage, do not touch any components located within the housing – either
with your hands or with any other objects – if mains voltage is applied or if the DC-bus capacitors
are not discharged. Do not carry out any work on the wiring or check any signals if mains voltage is
applied.
•
Exercise particular caution if automatic restart is activated. To prevent injuries caused by the
automatic restarting of the drive following a power failure, install a switching component at the
mains that is deactivated in the event of a power failure and that may only be switched on again on
return of the power supply (e.g. contactor etc.). Earth the drive at the connections intended for this.
ATTENTION
•
Ensure that the input voltage corresponds to the voltage indicated on the product nameplate.
Environmental influences such as high temperatures and high relative humidity are to be avoided as
well as dust, dirt and corrosive gases. The mounting location should be well ventilated and not
exposed to direct sunlight. Install the device on a non-flammable, vertical wall that does not transmit
any vibrations. Attention! Do not apply mains voltage to the output terminals U/T1, V/T2 and W/T3.
•
Please contact the motor or machine manufacturers if standard motors with frequencies >50 Hz are
to be used.
•
All Bulletin 161 drives are checked for dielectric strength and insulation resistance. Insulation
resistance measurements e.g. as part of a check may only be taken between the power terminals
and earth. Do not carry out any measurements at the control terminals.
•
In normal operation apply the START/STOP commands via the control terminals or the control panel
and not by disconnection and reapplying input power to the drive or motor contactor. Do not install
any capacitors or suppressors to the drive output terminals.
ATTENTION
•
To ensure that your Bulletin 161 drive functions safely and reliably, all the pertinent safety
regulations, e.g. accident prevention regulations, professional association regulations, EN, VDE
regulations etc. must be observed. As these regulations are implemented differently in different
countries, the user must observe the regulations that apply for his particular country. Rockwell
Automation cannot release the user from complying with the latest relevant safety regulations.
