Electrical connection
DANGER
Exposed electrical components.
Electric shock and injury due to live components (230V, 50Hz)!
•
Before working on electrical installations, disconnect all affected equipment from the power
supply.
• Observe the requirements for protection class II when laying the power supply cable.
Do not lay live cables.
• Lay the mains connection cables and data cables separately.
• Guide the system components of the ventilation system to the same automatic safety device.
Installation and connection must only be performed by qualified and trained personnel.
NOTE
Insufficient wire cross-section.
Excessive voltage drop and/or contact cannot be guaranteed!
Only use the following cable cross-sections:
• Power
cable:
1.5
mm²
• if selected: Connecting cable for e.g. pressure monitor: max. 0.8 mm²
• if selected: RS485 data cable:
0.25 – 0.5 mm², length max. 500 m
TIP:
When laying the cables, make sure that there is sufficient play, and observe the maximum cable
length.
The communication of the system components (Easy Connect e16 controller, Connect inner
covers, CS2-Connect CO

sensor) can be carried out via the 868 MHz radio network or RS485
data cable.
data cable. Accordingly, the following cabling is possible:
A: Connection/communication of the system components via 868 MHz radio network
B: Connection/communication of the system components via RS485 data cable
The combination of both connection types is possible. For example, communication between the
inner cover [ventilation device] and the controller can take place via RS485 data cable, while the
sensor system communicates with the controller via radio.
The following special features must be taken into account:
The battery-operated FTS19-Connect Indoor/Outdoor humidity/temperature sensors do not
require a mains connection. They communicate with the controller exclusively by radio; it is not
possible to connect an RS485 data cable.
The SK19-Connect switching contact has a 230 V connection, but also only communicates with
the controller by radio. The interface for connecting an RS485 data cable is used here to connect
the safety devices, e.g. a 4 Pa pressure sensor.
