Table 12-9 Acoustic noise data
* The acoustic noise figure for frame sizes 2C and 2D has been taken
with the bottom right angle ducting removed.
12.1.21 Overall dimensions
Refer to section 3.4 Mounting method on page 17.
12.1.22 Weights
Table 12-10 Overall drive weights
12.2 Cable and fuse size ratings
Maximum continuous input currents are given in section 2.1 Ratings on
page 6 to aid the selection of fuses and cabling. The maximum input
current is dependent on the ripple content of the output current. A value
of 100% ripple has been assumed for the given ratings.
The cable sizing selected when installing a Mentor MP must comply with
the local wiring regulations. The information provided in this section is
provided for guidance purposes only.
The power terminals on Mentor MP frame size 1 drives have been
designed to accommodate a maximum cable size of 150mm
2
(350kcmil)
with a temperature of 90°C (194°F).
The power terminals on Mentor MP frame size 2A drives have been
designed to accommodate a maximum cable size of 2 x 150mm
2
(2 x
350kcmil) with a temperature of 75°C (167°F).
The power terminals on Mentor MP frame size 2B drives have been
designed to accommodate 2 x 240mm
2
with a temperature of 90°C
(194°F). The use of cables sized using the US national electrical code as
shown in Table 12-13 requires the use of a terminal adaptor.
The power terminals on Mentor MP frame size 2C and 2D drives have
been designed for use with busbars. The drive can be used with cables
as shown in Table 12-13 with the use of a terminal adaptor.
The actual cable size depends on a number of factors including:
• Actual maximum continuous current
• Ambient temperature
• Cable support, method and grouping
• Cable voltage drop
In applications where the motor used is of a reduced rating, the cable
sizing selected can be appropriate for that motor. To protect the motor
and the output cabling the drive must be programmed with the correct
motor rated current.
When using reduced cable sizes, the branch circuit protection fuse rating
needs to be reduced in line with the cable size selected.
The following table shows typical cable sizes based on USA and
International standards, assuming 3 conductors per raceway/conduit, an
ambient temperature of 40°C (104°F) and applications with high output
current ripple content.
Table 12-11 Typical cable sizes for size 1 drives
1. The maximum cable size is defined by the power terminal housing
using 90°C (194°F) rated cables as per Table A.52-5 of the standard.
2. Assumes the use of 75°C rated cables, as per Table 310.16 of the
National Electrical Code.
The use of higher temperature rated cable would allow a reduction on
the minimum recommended cable size for Mentor MP shown above. For
high temperature cable sizing, please contact the supplier of the drive.
