Commissioning; Safety Instructions; Checks Prior To Commissioning - ABB SwirlMaster FSS430 Commissioning Instructions

DANGER
Danger of explosion if the device is operated with the
transmitter housing or terminal box open!
Before opening the transmitter housing or the terminal box,
note the following points:
— Check that a valid fire permit is available.
— Make sure that there is no explosion hazard.
— Before opening the device, switch off the power supply
and wait for t > 2 minutes.
NOTE
Damage to components!
If the cable is not fastened to the strain relief, the shielding
will not have a functional earth. Furthermore, there is a risk of
the cable being pulled completely out of the transmitter
housing should there be accidental strain, which would
interrupt the electrical connection. The sheath of the bus
cable must not be damaged. Otherwise, the IP rating IP67
for the flowmeter cannot be ensured.
1. Use the cable connected to the sensor to make the
electrical connection between the sensor and the
transmitter.
2. Unscrew the cover from the terminal compartment at the
rear of the transmitter.
3. Remove the insulation from the cable sheath, the shielding
and the wires as specified (see Fig. 27).
4. Insert the cable into the terminal compartment through the
cable gland and fasten the cable to the strain relief at a
height level with the shielding to prevent accidental
disconnection.
5. Tighten the cable gland.
6. Connect the bare wires to the corresponding terminals
(see Fig. 28).
7. Screw on the cover for the terminal compartment fully and
tighten hand-tight. Make sure the gaskets for the cover
are seated properly.

Before opening the transmitter housing or the terminal box,
note the following points:
— Check that a valid fire permit is available.
— Make sure that there is no explosion hazard.

CAUTION
Risk of burns on the sensor due to hot measuring media.
The surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
Before starting work on the sensor, make sure that the
device has cooled sufficiently.

Checks prior to commissioning

The following points must be checked before commissioning:
— The power supply must be switched off.
— The power supply must match the information on the
name plate.
— The wiring must be correct in accordance with the chapter
titled „Electrical connections" on page 21.
— The earthing must correct in accordance with the chapter
titled „Earthing" on page 22.
— The ambient conditions must meet the requirements set
out in the technical data.
— The sensor must be installed at a location largely free of
vibrations.
— The housing cover and its safety locking device must be
sealed before switching on the power supply.
— For devices with a remote mount design, ensure that the
sensor and transmitter are assigned correctly.
