5 INSTALLATION OF MULTIPLE CLUSTERED MASS SINE ULTRA’S
This installation instruction serves as a guideline for the safe
and effective installation of the Mass Sine Ultra in a multiple
configuration, i.e.
•
a parallel configuration, or
•
a split phase configuration, or
•
a three phase configuration, or
•
a combination of a split phase or three phase in a parallel
configuration.
5.1
Purpose of a multiple configuration
There are several reasons for a multiple configuration of the
Mass Sine Ultra:
•
If more output power is needed than one Mass Sine Ultra
can supply, two up to ten Mass Sine Ultra’s can be
connected in parallel;
•
If redundancy is required, Mass Sine Ultra’s can be
connected in parallel to maintain reliable power supply if
one of the Mass Sine Ultra’s fails in operation;
•
Three Mass Sine Ultra’s can be connected in a 3-phase
configuration to supply three phase AC power. By
connecting more Mass Sine Ultra’s in parallel as well,
virtually unlimited three phase power can be made
available.
5.2
General installation guidelines
When using Mass Sine Ultra’s in a multiple configuration, the
following requirements are:
•
Only identical Mass Sine Ultra’s with the same article
numbers may be used in a multiple configuration;
•
Maximum number of Mass Sine Ultra’s in parallel: 10;
•
Maximum number of Mass Sine Ultra’s in a three phase
-parallel configuration: 3 x 3;
•
Installation and commissioning of multiple Mass Sine
Ultra’s requires configuration of MasterBus settings and
programming of MasterBus events by means of a
MasterBus control panel or a PC (in combination with a
MasterBus USB-interface) with MasterAdjust software
installed. The installer must be familiar with MasterBus
configuration tools and the programming of such events;
•
Allow sufficient ventilation to prevent build-up of hot air.
When installing multiple Mass Sine Ultra’s either side by
side or vertically above each other, at least 10 cm / 4 inch
free space must be kept in between the units. If
necessary, adequate measures must be taken to avoid
one Mass Sine Ultra heating up the other.
