14 UL listing information
The drives have been assessed to meet both UL and cUL requirements.
The Control Techniques UL file number is E171230. Confirmation of UL
listing can be found on the UL website: www.ul.com.
14.1 Common UL information
Conformity
•
Size 1 to 3 standard drives conform to
C
UL
US
Type 1 as standard
•
Size 4 to 6 standard drives conform to
C
UL
US
open type as standard,
and
C
UL
US
Type 1 when the optional conduit box is installed
•
Size 1 to 3 E12/E54 and E12/E66 drives conform to
C
UL
US
Type 12
as standard
•
Size 4 to 6 E12/E54 drives conform to UL Type 12 as standard
For further information, refer to section 2.2
The drive conforms to
C
UL
US
listing requirements only when the
following are observed:
•
The standard Affinity drive is installed in a Pollution degree II
environment, or better, as defined by UL508C
•
The E12/E54 Affinity drive is installed in a Pollution degree III
environment, or better, as defined by UL508C
•
The terminal tightening torques specified in section 3.10.1
•
If the drive control stage is supplied by an external power supply
(+24V), the external power supply must be a UL Class 2 power
supply
Motor overload protection
The drive provides motor overload protection. The default overload
protection level is no higher than 113% of full-load current (FLC) of the
drive in open loop mode and no higher than 114% of full-load current
(FLC) of the drive in RFC mode. It is necessary for the motor rated
current to be entered into Pr
0.46
(or Pr
5.07
) for the protection to
operate correctly. The protection level may be adjusted below 150% if
required. Refer to section 8.2
information. The drive also provides motor thermal protection. Refer to
section 8.3
Overspeed Protection
The drive provides overspeed protection. However, it does not provide
the level of protection afforded by an independent high integrity
overspeed protection device.
14.2 Power dependant UL information
14.2.1 Affinity size 1 to 6
Conformity
Size 1 to 6 standard, size 1 to 3 E12/E54 and E12/E66 drives conform to
C
UL
US
, and size 4 to 6 E12/E54 drives conform to UL listing
requirements when the following are observed:
Ambient conditions
Size 1 to 6 standard, size 1 to 3 E12/E54 and E12/E66 drives
The surrounding air temperature does not exceed 40°C (104°F) when
the drive is operating.
Size 4 to 6 E12/E54 drives
The surrounding air temperature does not exceed 35°C (95°F) when the
drive is operating.
Fuses
Size 1 to 3
•
The correct UL-listed fast acting fuses (class CC or class J up to 30A
and class J above 30A), e.g. Bussman Limitron KTK-R series,
Ferraz Shawmut ATMR series or equivalent, are used in the AC
supply. The drive does not comply with UL if MCBs are used in place
of fuses.
For further details on fusing, refer to in Table 4-3 and Table 4-4 on page 72.
Size 4 to 6
•
The UL-listed Ferraz HSJ (High speed J class) fuses are used in the
AC supply. The drive does not comply with UL if any other fuses or
MCBs are used in place of those stated.
For further details on fusing, refer to Table 4-5 on page 73.
Field wiring
Size 1 to 4
•
Class 1 60/75°C (140/167°F) copper wire only is used in the
installation
Size 5 and 6
•
Class 1 75°C (167°F) copper wire only is used in the installation
Field wiring connectors
Sizes 4 to 6
•
UL listed wire connectors are used for terminating power circuit field
wiring, e.g. Ilsco TA series
14.3 AC supply specification
The drive is suitable for use in a circuit capable of delivering not more
than 100,000rms symmetrical Amperes at 264Vac rms maximum (200V
drives), 528Vac rms maximum (400V drives) or 600Vac rms maximum
(575V and 690V drives).
14.4 Maximum continuous output current
The drive models are listed as having the maximum continuous output
currents (FLC) shown in Table 14-1, Table 14-2, Table 14-3 and Table
14-4 (see Chapter 12
on page 228 for details).
The following values also apply to the E12/E54 drives.
Table 14-1 Maximum continuous output current (200V drives)
Fire Mode - Important Warning
When Fire Mode is active the motor overload and thermal
protection are disabled. Fire Mode is provided for use only in
emergency situations where the safety risk from disabling
overload protection is less than the risk from the drive tripping
- typically in smoke extraction operation to permit evacuation
of a building. Fire Mode is activated by setting Pr
1.53
(
Fire
mode set speed
) to a non-zero value and asserting digital
input 4. When operating in Fire Mode the drive displays a
flashing warning
Fire mode active
. Care must be taken to
prevent inadvertent activation of Fire Mode, as well as
ensuring that after using or testing the function the input is
returned to the normal state, as confirmed by the absence of
the flashing warning. Care must be taken to ensure that
Pr
1.53
or Pr
1.54
are not inadvertently re-allocated to
different inputs or variables. It should be noted that, by
default, Pr
1.54
is controlled from digital input 4 and changing
Pr
6.04
or Pr
8.24
can re-allocate this digital input to another
parameter. These parameters are at access level 2 in order
to minimize the risk of inadvertent or unauthorized changes.
It is recommended that User Security be applied to further
reduce the risk (see section 5.10
on page 97). These parameters may also be
changed via serial communications so adequate precautions
should be taken if this functionality is utilized.
