3.4 Mounting supply unit,
liquid cooling housing variant
Arrange the devices starting from the supply unit to the right (up to ServoOne
DC BG5) or left (from ServoOne DC BG6a) sorted in descending order by power
rating to minimise thermal interaction. Pay attention to the notes on effective EMC
installation prior to mounting the devices and components in the switch cabinet.
• Align the supply unit BG5 and all ServoOne DC axis controllers in a line along the top edge
of the devices (see line A in Figure 3.8). This action is necessary to be able to supply the DC
power using the pre-assembled cables.
• Align all ServoOne DC axis controllers and the supply unit BG6a in a line along the top edge
1.
of the devices (see line A in Figure 3.9). Move down the mounting bores for DC axis controller
BG6a and the supply unit BG6 by approx. 20 mm (see red line B in Figure 3.9). This action is
necessary to be able to make the DC link connections.
• Align all ServoOne DC axis controllers and the supply unit BG7 in a line along the top edge
of the devices (see line A in Figure 3.10). Move down the mounting bores for the supply unit
BG7 by approx. 28 mm and for the DC axis controller BG6a by approx. 20 mm (see red line
B in Figure 3.10). In addition, a distance of ≥ 40 mm must be maintained at the side (in the
figure to the right of the supply unit BG7). This action is necessary to be able to make the DC
link connection.
Mark out the position of the tapped holes and the pipe fittings on the backing plate.
Drill holes and cut a thread for each fixing screw in the backing plate.
Note the mounting distances. Also pay attention to the bending radius of the
2.
connection cables. For dimensional drawings/hole spacings see Figure 3.8 to
Figure 3.10 and Table 3.2.
Mount the supply unit vertically and butt-mounted in a row on the backing plate.
3. The contact area must be bare metal.
On screwing the hose connections (not included in the scope of supply) into the
pipe fittings, lock the pipe fittings using a 22 mm open-ended wrench to prevent
damage due to the application of torque to the device.
4.
Pay attention to a perfectly sealed connection without leaks (e.g. using Teflon
sealing tape).
You will find further notes on the liquid cooling in chap. A.4, p. 80.
