5.3 MASTERBUS CONNECTORS
The CS15TL/CS20TL is equipped with 2 x 2 MasterBus
connectors (A and B) to install two MasterBus networks.
Network A is reserved for the string box connected to the
CS15TL/CS20TL. The other network (B) is reserved for
future upgrades.

Proceed as follows to remount the communication module:
• Close any unused holes in the glands, using the
premounted caps.
• Insert communication module, using the guidance rails.
• Fix the Phillips screws at both sides of the front plate
(see figure 4).
For MasterBus connection of the CS-IT20
isolation transformer, refer to section 6.6.
The CS15TL/CS20TL is compatible with the
Sunmaster XL and XS inverter series, so it can
be combined with these inverters in the
MasterBus network.
5.4 MASTERBUS NETWORK
All devices that are suitable for MasterBus are
marked by the MasterBus symbol.
MasterBus is a fully decentralized data network for
communication between the different Mastervolt system
devices. The communication network is based on CAN-
bus which has proven a reliable bus-system. New devices
can be added to the existing network by just extending the
network. This gives the MasterBus network a high degree
of flexibility for extended system configuration. Mastervolt
also offers several interfaces, making even non-MasterBus
devices suitable to operate in the MasterBus network.
CAUTION: Never connect a non-MasterBus
device to the MasterBus network directly! This
will void warranty of all MasterBus devices
connected.
5.5 HOW TO SET UP A COMMUNICATION
NETWORK
Every device that is suitable for the RS 485 and
MasterBus network is equipped with two data ports. When
two or more devices are connected using these ports,
together they form a local data network.
Keep the following rules in mind:
Figure 11
Figure 12
MasterBus needs a terminating device on both ends
of the network. This is not needed for RS485.
