Cable connections
Preliminary remarks
The transmitter and receiver units are connected with a cable
(signal cable).
NOTICE
Impairment of device safety and function
Impairment of device safety, calibration or accuracy of the
device due to modification of the signal cable or cable glands.
• The cable glands or signal cables must not be replaced or
modified without the express permission of ABB.
• The max. length of the signal cable (transmitter to receiver
unit) is 150 m (492 ft).
• The max. length of the power cable (power supply to
transmitter unit) is 100 m (328 ft).
• The max. length of the (optional) Ethernet cable is
100 m (328 ft) or more (depending on configuration of local
network).
• The service PC cable is 3 m (9.8 ft) long, but can be extended
to approx. 10 m (32.8 ft).
Notes for installation
• If not pre-assembled at the factory, connect the power cable
and signal cable to the transmitter unit terminal box, see
Transmitter unit – signal cable to receiver unit
on page 26
and
Transmitter unit – power supply / analog inputs
page 20.
• If not pre-assembled at the factory, connect the signal cable
to the receiver unit, see
page 20.
• The input signals (such as external temperature and pressure
sensors) are connected to the corresponding terminals in the
transmitter unit, see
Transmitter unit – power supply /
on page 20.
Use the cable gland for power supply and analog inputs, see
Cable glands on the transmitter unit
on page 18.
If connected to the terminals in the transmitter the factory-
mounted wires should be removed from the terminals in
question.
• The power supply provided may only be installed outside the
potentially explosive atmosphere or in ATEX Zone 2 or CSA
Class I Division 2.
Note
• In the table columns labeled “Signal”, the indicated polarities
of the items are for naming only and do not necessarily
reflect the polarity of real voltages.
• All potentials are floating and none of them should be
grounded to box. This applies to all connection tables.
