Xylem IM250R03 Aquavar CPC-FD - Manual (Page 40)

Applicable Standards
Drive compliance with the following standards is identified by the standards “marks” on the type code label.
Mark Applicable Standards
UL 508C and UL Standard for Safety, Power Conversion Equipment, second
C22.2 No. 14 edition and CSA Standard for Industrial Control Equipment
UL 508A UL Standard for Safety, Industrial Control Panels
C22.2 No. 14 CSA Standard for Industrial Control Equipment
Compliance is valid with the following provisions:
• The motor and control cables are chosen as specified in this manual.
• The installation rules of this manual are followed.
The AQUAVAR is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 600 V maximum.
For open type enclosures, that is units without the conduit box and/or cover for enclosures, that is units without
the conduit box and/or cover for IP21/UL type 1 units or without the conduit place and/or top cover for IP54
units, the unit must be mounted inside an enclosure per National Electrical Code and local electrical codes.
UL/CSA Markings
A UL mark is attached to ACS550 drives to verify that the drive follows the provisions of UL 508C.
A CSA mark is attached to ACS550-U1 type drives to verify that the drive follows the provisions of C22.2
NO. 14.
The ACS550 is suitable for use in a circuit capable of delivering not more than 100 kA RMS symmetrical
amperes, 600 V maximum. The ampere rating is based on tests done according to UL 508.
Branch circuit protection must be provided in accordance with local codes.
The ACS550 has an electronic motor protection feature that compiles with the requirements of UL 508C
and, for ACS550-U1, C22.2 No. 14. When this feature is selected and properly adjusted, additional
overload protection is not required unless more than one motor is connected to the drive or unless
additional protection is required by applicable safety regulations. See parameters 3005 (
MOT THERM
PROT ) and 3006 ( MOT THERM RATE ).
The drives are to be used in a controlled environment.
Note: For open type enclosures, i.e. drives without the conduit box and/or cover for IP21 / UL type 1
drives, or without the conduit plate and/or hood for IP54 / UL type 12 drives, the drive must be mounted
inside an enclosure in accordance with National Electric Code and local electrical codes.
Brake choppers, when applied with appropriately sized brake resistors, will allow the drive to dissipate
regenerative energy (normally associated with quickly decelerating a motor). Frame sizes R1 and
R2 have a built-in brake chopper as standard equipment. For frame sizes R3…R6, contact your ABB
representative for appropriate parts.
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 the disconnecting device (disconnecting means);
instead, use the control panel start and stop keys and , 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.
