5. Mounting
The PowerPlex
®
Mini Module has been designed for stationary installation. This PowerPlex
®
module is used for
loads up to 10 A. We recommend to install the modules in close proximity to the loads to be controlled.
5.1. Installation check list
When planning and installing the PowerPlex
®
system please observe the limited number of system components.
Our recommendation is some 30 PowerPlex
®
modules per system. Maximum values depend on the configuration
scope so that more modules per system could be possible. Mounting covers the following installation steps listed
in Table 6:
Step Action
1 Application-specific system planning
2 Determine the installation site and prepare all necessary devices and tools
3 Put down the serial number
4 Run the cables
5 Prepare the necessary cut-outs for cables and device in the mounting plate
6 Connect the device for start-up
7 Mount and connect all remaining PowerPlex
®
components if not done before
8 Start the system by switching on
9 Check the system behaviour by a complete system test
Table 6: Installation check list
5.2. Recommended installation site
All PowerPlex
®
components can be installed in any location. The PowerPlex
®
HMI devices should be installed in
an area which offers maximum benefit for the user. The PowerPlex
®
modules on the other hand should be installed
close to the connected loads to reduce wiring efforts.
Important
•
Leave enough space for heat dissipation.
•
Please make sure to install the PowerPlex
®
modules in enclosed rooms.
•
Please observe the mounting version so as to reach the required degree of protection.
General requirements of installation site
When choosing the mounting site, various factors that might influence the performance of the device have to be
considered. Table 7 gives you an overview of the major factors.
Ventilation
Please ensure sufficient ventilation by leaving enough space at all sides of the device and ensure that
the vent holes are not blocked. Leave enough space between the devices.
Installation area
Ensure a tight installation on the mounting area. Please consider the vehicle-specific properties and
do not mount components in places where might affect the safety features of the vehicle. In addition,
make sure that the mounting surface is flat and even and not too rough so as to ensure the requested
protection degree.
Cable bushing
Ensure installation at a site where the cables can be laid and connected properly.
Electrical noise pulses
The installation site should provide sufficient distance to any devices that might emit noise pulses.
