1.10 Installation Safety Information; 1.11 Electrical Installation Safety Information - ABB FSM4000 Series Commissioning Instruction

1.10 Installation safety information

Observe the following instructions:
• The flow direction must correspond to the direction indicated on the device, if labeled.
• Comply with the maximum torque for all flange bolts.
• Install the devices without mechanical tension (torsion, bending).
Install flange and wafer type units with coplanar counter flanges.
•
• Only install devices for the intended operating conditions and with suitable seals.
Secure the flange bolts and nuts against pipeline vibrations.
•

1.11 Electrical installation safety information

The electrical connection may only be performed by authorized specialists according to the
electrical plans.
• Comply with electrical connection information in the manual. Otherwise, the electrical
protection can be affected.
• The line for the supply power must be installed according to the relevant national and
international standards. A separate fuse must be connected upstream and in close proximity
to each unit. The fuses must be identified accordingly. The unit has a protection class of I
and overvoltage class II (IEC664).
• The power supply and the electrical circuit for the magnet coils of the flowmeter sensor are
dangerous and pose a contact risk.
• The magnet coils and signal circuit can be connected with ABB flowmeters sensor only. Use
the supplied cable D173D147U01 for the magnet coil circuit. This does not apply for older
model flowmeter primaries 10D1422, 10DI1425 (≥ DN 500). In this event, the magnet coil is
supplied via the supply power (see name plate for the flowmeter sensor). Use the supplied
signal cable D173D025U01 for the measuring signal.
• Only electrical circuits that do not pose a contact risk can be connected to the remaining
signal inputs and outputs.
• Ground the measurement system according to requirements.
