Connecting
The SITRANS LUT400 is available in AC or DC power models.
1. To wire for power, strip the cable jacket for approximately 70 mm (2.75") from the end
of the cable, and thread the wires through the gland
1
.
2. Connect the wires to the terminals as shown: the polarity is identified below the
terminal block.
3. Ground the device according to local regulations.
Cables
The SITRANS LUT400 is designed to work with two conductor shielded transducer
cables.
1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof
applications.
Notes for AC power connections:
• The equipment must be protected by a 15 A fuse, or circuit breaker on all
current-carrying conductors in the building installation.
• A circuit breaker or switch in the building installation, marked as the disconnect
switch, must be in close proximity to the equipment and within easy reach of the
operator, and must disconnect all current-carrying conductors.

Warning:
Do not use a coaxial transducer cable
extension with the SITRANS LUT400. High voltage
transmitted on shield of coaxial cable could result in
personal injury, damage to equipment, or poor device
performance.
