Mains Supply - Kamstrup MULTICAL 403 Installation And User Manual

MULTICAL® 403

6.2 Mains supply

MULTICAL® 403 is available with supply
modules for either 24 VAC or 230 VAC.
The modules are protection class II and are
connected via two-wire cable (without earth)
through the big cable bush, the second one
from the right, at the bottom of the connection
base. Use connecting cable with an outer
diameter of 5-10 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
must not be protected by a fuse larger than
the one permitted for the given cable size, see
examples below.

or requirements for larger fuses than the
ones listed above, it is necessary to consult a
certified electrician for an individual evaluation
of how the type of installation in question
should be carried out.
In addition please note that work on the fixed
installations, including any intervention in the
fuse box, must be carried out by an authorized
electrician.
