3. Structured Wiring Box
Janus can be installed into nearly any structured wiring
enclosure using either the Universal Rack Ears or Universal
DIN Rail Brackets� Structured wiring enclosures are a
convenient and professional way to manage wiring and
mount supporting devices such as power supplies and SI�FI�

2. Using Universal DIN Rail Bracket
Similar to the Universal Rack Ear, the Janus Universal DIN Rail Bracket
features a symmetrical hole pattern which provides six total mounting
locations on Janus� Each Universal DIN Rail Bracket has multiple
threaded holes which accommodate
set screws to lock the Brackets in place
along the DIN Rail�
ALTERNATIVE MOUNTING OPTIONS
1. Using Universal Rack Ear
The symmetrical hole pattern of the Janus Universal Rack Ear allows these multi-functional Brackets to be
mounted on either side of Janus in any orientation� This makes it possible to mount Janus to virtually any
surface in multiple positions�

Note: Only 1 Bus IN and 1 Bus OUT
port can be used at any given time.
4. Connecting IP Control
SI�FI is intended to be treated as any other bus device, and plugged in to a motor port, the BUS IN port, or a
Somfy Data Hub� Regardless of which of these ports you plug the SI�FI in, your entire system will be controllable
over IP�
**SI�FI requires a separate cable connecting it to the IP network of the site**
UTP Face
3. Connecting BUS Devices
All motor ports on the UTP Face of Janus accept device inputs and can be used if the port is not needed for
a shade� Janus supports the use of 8 shades and 8 devices simultaneously if all motors are plugged in to the
Terminal Block Face while all devices are connected to the UTP Face�
