The ROTAMASS Coriolis owmeter is conform
to the European EMC Guideline and fullls the
following standards:
EN 61326-1: 2006;
EN 61326-2-3: 2006;
EN 61000-3-2: 2006;

ROTAMASS is a class A product and should be
used and installed properly according to the EMC
Class A requirements
The function ground terminal or the PE- terminal
have to be connected to protective ground to
ensure electro-magnetic interference protection.
To ensure the EMC specications the following
measures must be carried out :
1. Put the power cables through the ferrite core
clamp before connecting to the terminals as shown
in chapter ´ Installation ´ (Power supply wiring).
2. Put the I/O- cables through the ferrite core
clamp before connecting to the terminals as shown
in chapter ´ Installation ´ (Power supply wiring).
3. Connect protective ground conductor of power
supply to PE- terminal in the terminal box (see
chapter ´ Installation ´ (Power supply wiring).
4. In case of Explosion proof type instrument, fur-
ther requirements are described in chapter 9
“EXPLOSION PROTECTED TYPE INSTRUMENTS”.
The description in this chapter is prior to other de-
scriptions in this instruction manual.
IMPORTANT
Although the products has been designed to
resist high frequency electrical noise, if a radio
transceiver is used near the owmeter or its
external wiring, the transmitter may be affected by
high frequency noise pickup. To test for such
effects, bring the transceiver in use slowly from a
distance of several meters from the owmeter,
and observe the measurement loop for noise
effects. Thereafter, always use the transceiver
outside the area affected by noise.
