Mains connection
Mains connection is located on the relay board, terminal
J1
.
The R131VX must be used with a 3-wire mains connection (2W+PE @ min. 0,75 mm
2
,
PE=yellow/green, neutral=blue).
Note:
Terminals marked with hazardous live symbol
requires installation by an
instructed person.
The wires must be secured to the
Cable Anchoring Fingers
on the board using a cable tie.
Each wire must be connected exactly as shown on the fold-out page drawing.
The unit is designed for continous operation.
Warning:
Make sure correct mains voltage 230/115 VAC is selected with the voltage
selector
S2
prior to activating the mains switch.
Mains voltage selector and mains fuse
Prior to connecting mains voltage make sure the correct nominal mains voltage 230VAC
(factory default position) or 115 VAC is selected with
S2
located on the relay board.
The mains fuse
F1
located on the relay board is factory set for 230 VAC operation. A fuse
suitable for 115 VAC operation is included in the connection kit.
Replace with same type and rating only; i.e.:
v
230 VAC: T500mA
v
115 VAC: T1A
LON

Network Installation
All SYSTEM X components (nodes) are connected together in a common
L
ON
W
ORKS
®
communication network.
The network is polarity insensitive and therefore either of the two twisted pair wires can be
connected to either of the LON
®
connectors on the SYSTEM X components.
Due to the risk of cross-talk/interference, it is recommended not to run LON
®
Network cables
close to high voltage cable, or cables carrying video signals.
In countries where the CE approval is mandatory, LON
®
cables with an overall
screen must be used in order to comply with EMC/EMI standard EN 50130-4.
The cable screen should be connected to the cable clamp next to the LON
®
connector.
