14 UL Information
Quantum MP frame size 1 drives have been assessed to comply with
both ULus and cUL requirements.Control Techniques UL file number is
E58592. Confirmation of UL listing can be found at website: www.ul.com
Quantum MP frame size 2 drives have been assessed to comply with
UL508A open panel requirements.
14.1 Common UL Information
Conformity: The drive conforms to UL listing requirements only when the
following are observed:
1. The drive is installed in a type 1 enclosure, or better as defined in UL
50.
2. The ambient temperature does not exceed 40°C when the drive is
operating.
3. The terminal torques specified in section 3.8.3 Torque settings on
page 23 are to be used.
4. The drive is to be installed in to a pollution degree 2 environment.
5. 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.
6. Fuses sized as specified in the various tables in Chapter 4 Electrical
Installation on page 26 are to be used. Fusing is to incorporate a
Class J fuse in line with a semiconductor fuse as specified.
7. Field wiring is to be class 1 75°C (167°F) copper wire only.
Motor overload protection
All models incorporate an internal overload protection model for the
motor load that does not require the use of an external or remote
overload protection device.
The protection level is adjustable, and the method of adjustment is
provided with the instructions for the product.
Maximum current overload is dependant on the values entered into the
current limit parameters (motoring current limit, regen current limit and
symmetrical current limit entered as percentage) and the motor rated
current parameter (entered in amperes).
The duration of the overload is dependant on motor thermal time
constant (variable up to a maximum of 3000 seconds). The default
overload protection is set such that the product is capable of 150% of the
current value entered into the motor rated current parameter (Pr 5.07
(SE07, 0.28)) for 30 seconds. The product also provides user terminal
default functionality such that the product can be connected to a motor
thermistor to protect the motor in terms of temperature, in the event of a
motor cooling fan failure.
Over speed 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 AC supply specification
The maximum UL supply voltage is 600 Vac.
The drive is suitable for use in a circuit capable of delivering not more
than 100,000 rms symmetrical Amperes at 575V (size 1A and 1B).
14.3 Maximum continuous output current
The drive models are listed as having the maximum continuous output
currents (FLC) shown in Chapter 2.2 Ratings on page 6.
14.4 Safety label
The safety label supplied with connectors and mounting brackets must
be placed on a fixed part of the drive enclosure where it can be seen
clearly by maintenance personnel for UL compliance.The label clearly
states "CAUTION risk of electric shock power down at least 10 minutes
before removing cover".
