*overall cable length above 1000ft/300m shall be avoided
DC resistance must not exceed 4Ω; according to IEC62386-101:2014.
Both Electrical and Logical limitations of Digital bus shall be considered when sizing / designing of the lighting control system.

Wiring Input interfaces on controller
Warning
: negative terminals are common internally. Loops should be avoided
Maximum cable length for inputs: wiring DC resistance must not exceed 100Ω

**care should be taken applying cable lengths above 1650ft/500m as it can harmfully influence stability.
Separation of circuits
Warning
: the wiring shall be installed in accordance with National Electric Code and local codes rules; the power wiring
must be separated accordingly from the class 2 signal wiring
Power wiring - AC power input and the relay outputs
Signal wiring - Ethernet, input interfaces and Digital Bus A/B
Electrical limitations of each Digital bus
Max current load on each bus = 175mA
When connecting devices calculate power consumption of
the devices on the bus
• Control Gear: 2 mA**
• Lightsweep™ Digital Switch Interface: 2 mA
• Lightsweep™ Digital Multisensor 2: 3 mA
Logical limitations of each Digital bus
• Max number of Digital control gears applicable per bus: 64 pcs
• Max number of Digital input devices applicable per bus: 64 pcs
Input devices are GE Digital switches and sensors. In terms
of connecting 3rd party Digital devices please contact
support.
Lightsweep™ system requires wired network for operation
and wireless (Wi-Fi) network for commissioning and setup
(In case of standalone deployment, this can be a temporary
network).
Lightsweep™ devices should be placed into an independent
broadcast domain in the network, separated from any other
devices and communications. These Controllers can obtain
their IP addresses with DHCP, therefore an active IPv4 DHCP
service should be available in this network segment. Static
IP addresses are not supported.
The hand held device with the commissioning application
should be connected to the same network segment. The
proper Wi-Fi coverage in the whole commissioning area is
an essential need.
