3.2.4 Mounting the MotiFlex
e
100
Ensure you have read and understood the
Mechanical installation and location requirements
in
section 3.2. Mount the MotiFlex
e
100 vertically on its rear side, the side opposite the front panel.
M5 bolts or screws should be used to mount the MotiFlex
e
100. Detailed dimensions are shown
in section 3.2.1.
Note: The 48 A and 65 A MotiFlex
e
100 have a recess at the rear of the product which is
filled with a block of packaging foam. Remove this foam before mounting the drive.
For effective cooling, the MotiFlex
e
100 must be mounted upright on a smooth vertical metal
surface. The MotiFlex
e
100 is designed to operate in an ambient temperature of 0 °C to 45 °C
(32 °F to 113 °F). Output current must be derated between 45 °C (113 °F) and the absolute
maximum ambient temperature of 55 °C (131 °F). All models incorporate cooling fans and are
designed to operate without any additional cooling methods.
Temperature derating characteristics are shown in sections 8.3.5 to 8.3.14.
3.2.4.1 Mounting multiple drives for DC bus sharing
The MotiFlex
e
100 is designed to be mounted in close contact with other MotiFlex
e
100s, to allow
the optional DC busbar kits (Baldor parts OPT-MF-DC-A, -B, -C or -D) to be connected across
the top of the drives. Each busbar kit contains two busbars and the necessary screws. When
mounting drives for DC bus sharing it is essential that they are accurately positioned in contact
with the neighboring drive, otherwise the busbars will not fit.
Mount the rightmost drive first, but do not fully tighten the top left screw. Take the next drive and
hold it against the left side of the first drive. Slide it downwards until the alignment tab (see Figure
4) on the side of the mounting flange fits behind the matching cutout on the first drive’s mounting
flange. Tighten the first drive’s top left screw. Holding the second drive in place, mark its mounting
holes. Remove the second drive, finish the mounting holes and then remount the drive. Use the
same procedure to mount further drives to the left of the second drive.
