3.1 Notes for installation
y
During the installation work
it is imperative you avoid ...
− Drill chippings, screws or other foreign bodies falling into the device.
− Moisture entering the device.
y
Switch cabinet
− The device is designed only for installation in a stationary switch cabinet.
The switch cabinet must as a minimum provide IP4X protection. According
to EN ISO 13849-2 the switch cabinet must have IP54 protection or higher
when using the safety functions (STO and SBC) in the axis controller.
y
Environment
− The devices must not be installed in areas where they are exposed to
continuous vibration. You will find more information in the appendix.
y
Soiling
− Maximum pollution degree 2 in accordance with EN 60664-1. Further
information on ambient conditions can be found in the appendix.
y
Effective EMC installation
− To obtain the best result for effective EMC installation you should use a
conductive, well-earthed, chromated or galvanised backing plate.
− If backing plates are varnished, remove the coating from the contact area!
The devices themselves have a chromated zinc frame.
Note:
If the ServoOne CM-L charging module and the
ServoOne CM-A active supply unit are installed in the axis group. it is
imperative the operation manuals for the other devices (axis controller,
controller, etc.) are also followed.
3.1.1
Order and arrangement
The following basic guidelines apply to the arrangement and installation of the
ServoOne CM-L charging module and the ServoOne CM-A active supply unit,
ServoOne CM-D active supply unit and the axis controllers.
y
Butt mounting and alignment
− The devices can be mounted directly beside each other without any spacing.
They are fastened to the backing plate using screw joints.

− The ServoOne CM-L charging module must always be mounted directly to
the left of the ServoOne CM-A active supply unit.
− The 24 V DC control supply must be provided by an external power supply
unit (e.g. ServoOne CM-S). For details see <SOCM Manual>. All devices in
the axis group - supply unit (SO CM-P, SO CM-A), axis controller (SO CM),
capacitance module (SO CM-C), expansion module (SO CM-E) and the
controller (MO CM) - are connected together using the 24 V busbars.
Given the same cooling concept, these connections can be made without
additional compensation measures in relation to the device depth.
− DC link busbars are available for the power supply.
− The devices must be mounted in the stipulated order one against the other -
see Figure 3.1. For details see <SOCM Manual>.
Note:
A maximum of 8 cross-communication bus users can be connected and
operated on a ServoOne CM-P supply unit (BG3+4) or ServoOne CM-A or
ServoOne CM-D. A cross-communication group is allowed to consist of a
maximum of 9 bus users.
Note:
It is not allowed to connect SO CM axis controllers BG1 and BG2 directly
to an SO CM-P supply unit BG3+4 or ServoOne CM-A or ServoOne CM-D.
Connection is only allowed if the SO CM-E expansion module is used. Pay
attention to Operation Manual SO CM-E Expansion Module and SO CM
Manual!
