Information
11 UL Listing Information
Size 0 drives have been assessed to meet UL requirements.

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
• The surrounding air temperature does not exceed 40°C (104°F) when the drive is
operating
• The terminal tightening torques specified in Figure 3-8 Features of the size 0 to 6
drive on page 25.
• 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 150% of full-load current (FLC) of the drive in open loop mode and no higher
than 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 the Unidrive SP User Guide for more information. The drive also
provides motor thermal protection. Refer to the Motor thermal protection section of 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.

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 Table 2-1 in section 2.1 Ratings on page 8.

• 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 2-2 in section 2.1 Ratings on page 8.
