Part A System installation and start-up

1 Electrical connection: power supply

1.1 Location and important installation notes PLEASE NOTE !

• Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current

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

• Do not cross or loop cables inside the terminal compartment.

• Use separate cable entries (PG screwed conduit entries) for power supply,

field current cables, signal lines, outputs and inputs.

• Hazardous locations are subject to special regulations, see Section 6.1 and special

installation instructions for hazardous-duty (”Ex”) versions.

• Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight.

Fit a sunshade if necessary.

• When installed in switchgear cabinets, signal converters must be adequately cooled,

e.g. use fans or heat exchangers.

• Do not expose signal converters to intense vibration.

Onl

y for separate systems/signal converters (F Versions)

• Keep distance between primary head and signal converter as short as possible.

Refer to Sect. 1.3.4 for maximum permissible length of signal and field current cables.

• Use the supplied Krohne signal cable A (Type DS), standard length 10 m (33 ft).

• Always calibrate primary head and signal converter together. Therefore, when installing,

ensure primary constant GK is identical; refer to instrument nameplate for the primary

head. If the GK is not identical, set the signal converter to the GK of the primary head.

Refer also to Sections 4 and 8.5.

• Dimensions of signal converter; refer to Section 10.2.
