UL Listing

13.1

General

Drive sizes 1 to 6 have been assessed to meet both UL and cUL
requirements.
UL listings can be viewed online at www.UL.com. The UL file number is
E171230.
13.2

Mounting

Drives can be installed in the following configurations:
• Standard or surface mounted. This is described in section
3.5.1 Surface mounting on page 28.
• Bookcase mounted. Drives are mounted side by side with no space
between them. This configuration minimizes the overall width of the
installation.
13.3

Environment

Drives are able to meet the following UL/NEMA environmental ratings:
• Type 1. The drive must either be installed with a UL Type 1 kit or be
installed in a Type 1 enclosure.
• Type 12. The drive must be installed in a Type 12 enclosure.
• The remote keypad is rated to both UL Type 1 and UL Type 12.
• Drives must be installed in a pollution degree 2 environment or
better.
13.4

Electrical installation

The following precautions must be observed:
• Drives are rated for use at 40 °C and 50 °C surrounding air
temperature.
• The temperature rating of the power cables must be at least 75 °C.
• If the drive control stage is powered from an external power supply
(+24 V), the power supply must be listed or recognized to UL class 2
with appropriate fusing.
• Ground connections must use UL listed closed loop (ring) terminals.
13.5

UL listed accessories

The following options are UL listed:
• CI-Keypad
• CI-485 Adaptor
• AI-485 Adaptor
• AI-Backup Adaptor
• Remote Keypad
• UL Type 1 kit
• NV Media card
13.6

Motor overload protection

The drives are installed with solid state motor overload protection.
The default overload protection level is less than 150 % of full load rated
current for open loop operation.
The default overload protection level is less than 180 % of full load rated
current for rotor flux control operation.
In order for the motor protection to work correctly, the motor rated
current must be entered into Pr 00.006 or Pr 05.007.
The protection level may be adjusted below 150% if required. See
section 8.3 Current limits on page 95.
13.7

Motor overspeed protection

The drive is installed with solid state motor overspeed protection.
However, this feature does not provide the level of protection provided
by an independent, high-integrity overspeed protection device.

Thermal memory retention

Drives incorporate thermal memory retention that complies fully with the
requirements of UL508C.
The drive is provided with motor load and speed sensitive overload
protection with thermal memory retention that complies with the US
National Electrical Code (NFPA 70) clause 430.126 and Underwriters
Laboratories Standard UL508C, clause 20.1.11 (a). The purpose of this
protection is to protect both drive and motor from dangerous overheating
in the event of repeated overload or failure to start, even if the power to
the drive is removed between overload events.
For full explanation of the thermal protection system, refer to section
8.4 Motor thermal protection on page 95.
In order to comply with UL requirements for thermal memory retention, it
is necessary to set the Thermal Protection Mode (04.016) to zero; and
the Low Frequency Thermal Protection Mode (04.025) must be set to 1 if
the drive is operated in Heavy Duty mode.
Alternatively, an external thermal sensor or switch may be used as a
means of motor and drive overload protection that complies with the
requirements of UL508C, clause 20.1.11 (b). This protection method is
particularly recommended where independent forced cooling of the
motor is used, because of the risk of overheating if the cooling is lost.
External thermal sensor
The drive is provided with a means to accept and act upon a signal from
a thermal sensor or switch imbedded in the motor or from an external
protective relay. Refer to section 4.10.2 Control terminal specification on
page 70.
13.9

Electrical ratings

• Drives are listed for connection to an AC supply capable of
delivering no more than 100 kA symmetrical amperes. See Table 4-5
• Power and current ratings are given in Table 11-1to Table 11-5.
• Fuse and circuit breaker (size 1 only with short circuit rating of 10
kA. Only the listed DIVQ/DIVQ7 type SU203UP ABB (E212323)
circuit breaker may be used) ratings are given in Table 4-6to Table 4-
9.
• Unless indicated otherwise in Table 4-6to Table 4-9, fuses may be
any UL listed Class J or CC with a voltage rating of at least 600 Vac.
• Unless indicated otherwise in Table 4-6to Table 4-9, circuit breakers
may be any UL listed type, category control number: DIVQ or
DIVQ7, with a voltage rating of at least 600 Vac.
13.10

cUL requirements for frame size 4

For frame size 4, models Mxxx-042 00133A, Mxxx-042 00176A, Mxxx-
044 00135A and Mxxx-044 00170A, transient surge suppression shall
be installed on the line side of this equipment and shall be rated 480 Vac
(phase to ground), 480 Vac (phase to phase), suitable for overvoltage
category III, and shall provide protection for a rated impulse withstand
voltage peak of 6 kV and a clamping voltage of maximum 2400 V.
NOTE
Mxxx denotes M100, M101, M200, M201, M300 or M400.
13.11

Group installation

13.11.1 Definition
Group Installation Definition: A motor branch circuit for two or more
motors, or one or more motors with other loads, protected by a circuit
breaker or a single set of fuses.
13.11.2 Limitations on use
All motors rated less than 1 hp
The drives may be used in group installations where each of the motors
is rated 1 hp or less. The full-load current rating of each motor must not
exceed 6 A. The motor drive provides individual overload protection in
accordance with the NEC clause 430.32.
