flowIQ® Gateway
6.5 Connecting the power supply
By connecting to 24 V or 230 V supply, there is a risk of electric shock.
6.5.1 Battery supply
flowIQ® Gateway can be delivered with battery supply with a number of various batteries. Optimal
battery lifetime is obtained by keeping the battery temperature below 30 °C. An info code/alarm
indicates if the battery level is low. The battery cannot and must not be charged and must not be
short-circuited. Used batteries must be handed in for approved destruction, e.g. to Kamstrup A/S.
6.5.2 Mains supply
flowIQ® Gateway is available with supply modules for either 24 VAC/VDC or 230 VAC.
The supply modules are protection class II and are connected via a two-wire cable (without earth)
through the big cable bush at the bottom of the connection base. Use connecting cable with an
outer diameter of 5-8 mm and ensure correct cable stripping as well as correct mounting of cable
relief. If connecting to 230 VAC, it is important to make sure that the whole installation complies
with current regulations. The supply cable for the meter must never be protected by a fuse larger
than the one permitted.
In case of doubt, it is recommended to take advice from an authorized electrician and get an
individual assessment of the execution of the installation in question. In addition, note that
work on fixed installations and any intervention in the fuse box must be done by an authorized
electrician only.
If flowIQ® Gateway is ordered with 24 VAC/VDC or 230 VAC power supply, please follow the steps
below to connect power.
