3.1 Introduction

3.1.1 Mounting

The FCD 302 consists of two parts: The installation box and
the electronic part.

Stand alone mounting

•

The holes on the rear of the installation box are
used to fix mounting brackets

•

Ensure that the strength of the mounting location
can support the unit weight

•

Make sure that the proper mounting screws or
bolts are used

Applications

3.1.1.1 Hygienic Installation

The FCD 302 is designed according to the EHEDG
guidelines, suitable for installation in environments with
high focus on ease of cleaning.

Mount the FCD 302 vertically on a wall or machine frame,
to ensure liquids drain off the enclosure. Orient the unit so
the cable glands are located at the base.

Use cable glands designed to meet hygienic application
requirements, for example Rittal HD 2410.110/120/130.
Hygienic-purpose cable glands ensure optimal ease of
cleaningin the installation.

NOTE

Only frequency converters configured as hygienic
enclosure designation, FCD 302 P XXX T4 W69, have the
EHEDG certification.
