2 Mounting and Installing
2.1 Introduction
2.2 Mounting of the BMS
Interface
2.3 Installation of the
BMS Interface
Together with the BMS Interface, three cables will be supplied:
- power supply cable
- communication cable to the (solar) control of the water heater
- communication cable to connect the BMS Interface to the building management
system (Modbus)
The BMS Interface should be mounted in the following way:
1. Remove the cover of the BMS Interface
2. Mount the rear side of the BMS Interface to the wall with fitting plugs.
The BMS Interface should be installed in the following way:
1. Connect the power supply cable, via the pull relief, to the
three way connector on the upper right side of the BMS
Interface. Connect the other side of the cable to the
power grid by using a double-pole isolator.
ATTENTION:
Do not power up the system until all the electrical
connections have been made.
2. Connect the communication cable to the water heater,
via the pull relief, to the two way connector on the lower
right side of the BMS Interface.
3. In case of a SGE or SGS solar system, connect this communication cable to the
blue two-way connector on the upper right side of the solar control, which is supplied
with the water heater.
