Xylem IM250R03 Aquavar CPC-FD - Manual (Page 3)

WARNING! The AQUAVAR CPC adjustable speed AC drive with Input Disconnect should ONLY be
installed by a qualified electrician.
WARNING! Even when the motor is stopped, dangerous voltage is present at the Power Circuit terminals
U1, V1, W1 and U2, V2, W2 and, depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
WARNING! Dangerous voltage is present when input power is connected. After disconnecting the
supply, wait at least 5 minutes (to let the intermediate circuit capacitors discharge) before removing the
cover.
WARNING! Even when power is removed from the input terminals of the AQUAVAR CPC, there may be
dangerous voltage (from external sources) on the terminals of the relay outputs.
WARNING! When the control terminals of two or more drive units are connected in parallel, the auxiliary
voltage for these control connections must be taken from a single source which can either be one of the
units or an external supply.
WARNING! The AQUAVAR CPC will start up automatically after an input voltage interruption if the
external run command is on.
WARNING! When the AQUAVAR CPC with Input Disconnect is connected to the line power, the Motor
Terminals T1, T2 and T3 are live even if the motor is not running. Do not make any connections when the
AQUAVAR CPC with Input Disconnect is connected to the line. Disconnect and lock out power to the
drive before servicing the drive. Failure to disconnect power may cause serious injury or death.
NOTE! For more technical information, contact the factory or your local AQUAVAR representative.
WARNING! Do not attempt to install or remove EM1, EM3, F1 or F2 screws while power is applied to
the drive’s input terminals.
WARNING! Do not control the motor with disconnecting device (disconnecting means); instead, use
the control panel start and stop keys, or commands via the I/O board of the drive. The maximum allowed
number of charging cycles of the DC capacitors (i.e. power-ups by applying power) is five in ten minutes.
WARNING! The opening of a branch-circuit protective device may be an indication that a fault has been
interrupted. To reduce the risk of fire or electric shock, current-carrying parts and other components of
the controller should be examined and replaced if damaged or equivalent.
USE OF WARNINGS AND NOTES
There are two types of safety instructions throughout this manual:
• Notes draw attention to a particular condition or fact, or give information on a subject.
• Warnings caution you about conditions which can result in serious injury or death and/or damage to the
equipment. They also tell you how to avoid the danger. The warning symbols are used as follows:
DANGEROUS VOLTAGE WARNING warns of high voltage which can cause physical injury and/or
damage to the equipment.
GENERAL WARNING warns about conditions, other than those caused by electricity, which can result
in physical injury and/or damage to the equipment.
