Quick Start Up
Important Safety Information
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
WARNING
Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the
equipment and possible injury or death.
This variable speed drive product (PACMotion VFD) is intended for professional incorporation into complete
equipment or systems as part of a xed installation. If installed incorrectly it may present a safety hazard. The
PACMotion VFD uses high voltages and currents, carries a high level of stored electrical energy, and is used
to control mechanical plant that may cause injury. Close attention is required to system design and electrical
installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only
qualied electricians are allowed to install and maintain this product.
System design, installation, commissioning and maintenance must be carried out only by personnel who
have the necessary training and experience. They must carefully read this safety information and the
instructions in this Guide and follow all information regarding transport, storage, installation and use of the
PACMotion VFD, including the specied environmental limitations.
Do not perform any ash test or voltage withstand test on the PACMotion VFD. Any electrical measurements
required should be carried out with the PACMotion VFD disconnected.
WARNING
Electric shock hazard! Disconnect and ISOLATE the PACMotion VFD before attempting any work on it. High
voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the
electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power
terminals prior to commencing any work.
Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have
elapsed after turning off the supply.
Ensure correct earthing connections and cable selection as dened by local legislation or codes. The drive
may have a leakage current of greater than 3.5 mA; furthermore the earth cable must be sufcient to carry
the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or
MCB should be tted in the mains supply to the drive, according to any local legislation or codes.
Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external
control circuits.
The “Safe Torque Off” Function does not prevent high voltages from being present at the drives power terminals.
