ULTRAFLOW® 54 DN15-125

6.11.2.2

Connection of power supply

If ULTRAFLOW® is connected via Pulse Transmitter or Pulse Divider, ULTRAFLOW® is supplied by the supply

module/battery mounted in Pulse Transmitter/Pulse Divider.

Pulse Transmitter/Pulse Divider is fitted with a D-cell lithium battery with connector. The battery is connected to the

output module.

Optimal battery lifetime is obtained by keeping the battery temperature below 30 °C, e.g. by wall-mounting of Pulse

Transmitter/Pulse Divider.

The voltage of a lithium battery is almost constant throughout the lifetime of the battery (approx. 3.65 V). Therefore, it

is not possible to determine the remaining capacity of the battery by measuring the voltage.

The battery cannot and must not be charged and must not be short-circuited.

The battery must be replaced by a corresponding lithium battery with connector from Kamstrup A/S. Used batteries must

be handed in for approved destruction, e.g. to Kamstrup A/S (see chapter 12 Disposal).

The mains supply modules are protection class II and are connected to the interface module via a short two-wire cable

with connector. The modules are powered via a two-wire mains supply cable (without earth connection) through the

cable connector of Pulse Transmitter/Pulse Divider. Use supply cable with an outer diameter of maximum 10 mm and

ensure correct stripping of insulation as well as correct tightening of cable screw connection. (See paragraph 6.11.2.2.4)

Max permitted fuse: 6 A.
