The working voltage range of the 24V power supply is as follows:
Maximum continuous operating voltage: 30.0 V
Minimum continuous operating voltage: 19.2 V
Nominal operating voltage: 24.0 V
Minimum start up voltage: 21.6 V
Maximum power supply requirement at 24V: 60 W
Recommended fuse: 3 A, 50 Vdc
Minimum and maximum voltage values include ripple and noise. Ripple and noise
values must not exceed 5%.
4.6 Cable and fuse size ratings
Maximum continuous input currents are given in section 2.2 Current ratings on page 9
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 150 mm
2
(350 kcmil) 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 150 mm
2
(2 x 350 kcmil) 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 240 mm
2
with a temperature of 90 °C (194 °F). The use of cables
sized using the US national electrical code as shown in Table 4-8 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 4-8 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.
The selection of the correct fuse is essential to ensure the safety of the installation
