UL Listing Information

The Control Techniques UL file number is E171230. Confirmation of UL listing can be
found on the UL website: www.ul.com.

Common UL information

Conformity
The drive conforms to UL listing requirements only when the following are observed:
• The drive is installed in a type 1 enclosure, or better, as defined by UL50
• Class 1 60/75°C (140/167°F) copper wire only is used in the installation
• The ambient temperature does not exceed 50°C (122°F) when the drive is
operating
• The terminal tightening torques specified in section 10.2 on page 260
• 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 overload protection level is 150% of
full-load current (FLC) of the drive in open loop mode and 175% of full-load current
(FLC) of the drive in closed loop vector or servo modes. 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 Current
limits in the Unidrive SP User Guide for more information. The drive also provides motor
thermal protection. Refer to Motor thermal protection in the Unidrive SP User Guide.
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.

Power dependant UL information

Unidrive SP Size 1, 2 and 3
Conformity
The drive conforms to UL listing requirements only when the following is observed:
• The correct UL-listed fast acting fuses (class CC up to 30A and class J above 30A),
e.g. Bussman Limitron KTK series, Gould Amp-Trap ATM series or equivalent, are
used in the AC supply. The drive does not comply with UL if MCBs are used in place
of fuses.

AC supply specification

The Unidrive SP is suitable for use in a circuit capable of delivering not more than
5000rms symmetrical Amperes at 264Vac rms maximum (200V drives), 528Vac rms
maximum (400V drives) or 600Vac rms maximum (575V drives).
