1 Electrical connection: power supply

1.1 Important installation notes

1.1.1 Location Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current installations with

Do not cross or loop cables inside the terminal compartment.

Use separate cable entries (see below) for power supply, field current cables, signal lines, outputs and inputs.

Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight. Fit a sunshade if necessary.

When installed in cabinets, signal converters must be adequately cooled, e.g. use fans or heat exchangers.

1.1.2 Only for separate systems/signal converters (W versions) Use the supplied KROHNE signal cable A (Type DS), standard length 5 m (16 ft).

1.1.3 Cable entries

line voltages up to 1000 V” or equivalent national regulations.

Do not expose signal converters to intense vibration.

Keep distance between flow sensor and signal converter as short as possible. See Sect. 1.3.4 for maximum permissible length of signal and field current cables.

Always calibrate flow sensor and signal converter together. Therefore, when installing, ensure primary constant GKL is identical; see instrument nameplate for the flow sensor. If the GKL is not identical, set the signal converter to the GKL of the flow sensor. Refer also to Sections 4.

NOTE: Ensure gaskets are fitted correctly and maintain the following max. torques!

3 Gasket

A) M 20 cable entries These cable entries may only be used for flexible electrical cables if the relevant electrical regulations so allow,

B) ½" NPT adapters C) ½" PF adapters For most North American systems the regulations require that electrical conductors be laid in conduits,

1/2" NPT or 1/2" PF adapters: 4 Nm / 2.8 ft × lbf

Max. torques for M 20 only: 3 Nm / 2.1 ft × lbf

e.g. National Electric Code (NEC). Do not fix rigid metal conduits (IMC) or flexible plastic conduits to the M 20 cable entries, refer to “Point B, C” below (1/2” NPT or PF adapters).

particularly for power voltages > 100 V AC. In such cases, use the 1/2" NPT or 1/2" PF adapters to which flexible plastic conduits can be screwed. Do not use rigid metal conduits (IMC)! Lay conduits such that no moisture can penetrate into the converter housing. Should there be risk of any condensation water forming, inside cross-section of the conduit around the cables at these adapters with a suitable sealing compound.

be kept closed. The selected creepage distances and clearances have been sized in conformity with VDE 0110 and IEC 664 for contamination category 2. Supply circuits and output circuits are designed to meet the standards

Safety isolation: the flowmeters (signal converters) must be provided with an isolating facility.

Use of the KROHNE shielded signal cable type DS with foil screen and magnetic shield will ensure proper operation of the equipment.

Connect shields via stranded drain wires. Underwater and underground installation possible. Insulating material is flame-retardant to IEC IEC 332.1 / VDE 0742. Signal cables are low in halogen, unplasticized, and stay flexible at low temperatures.

The grounding conductor should not transmit any interference voltages. Do not ground any other electrical device together with this conductor. The flow sensor is connected to ground by means of an FE functional ground conductor. Special information on grounding various flow sensors is contained in the separate installation instructions for flow sensors. These instructions also contain detailed descriptions on how to use grounding rings and how to install flow sensors in metal or plastic pipes or internally coated pipelines.
