3.3 Accessories for installation

3.3.1 Weather protection cover

CYY 101

The weather protection cover CYY 101 can be

installed directly on upright post of assembly

holder CYH 101 by means of 2 screws (M8),

see fig. 3.7, mounting position ➀.

Installation on vertical or horizontal tubing and

upright posts (max. diameter 70 mm) requires

an additional round post mounting kit (see

chapter 9.1).

3. Installation mycom CLM 121 / 151 - CD/MM

4. Electrical connection

4.1 Connection principles

Warning:

•The instrument must be grounded

before start-up!

•A mains disconnecting device

must be installed close to the

instrument and identified as a

mains disconnecting device for

the CLM 121 / 151-CD/MM

(see EN 61010-1).

•If malfunctions can not be

remedied, the instrument must be

removed from service and

secured to prevent accidental

start-up.

•Repair work can only be carried

out directly by the manufacturer or

by the Endress+Hauser service

organization.

Caution:

•All lines conducting signals are to

be shielded and run separately

from other control lines.

•Immunity to interference can only

be guaranteed for a properly

grounded instrument with a

screened measured value

output line.

The grounding of the screen must

be kept short. No soldered

extensions of the screen!

This is also valid for connection of

junction box VS (see chapter 3.3.2).

•For installation of field housing

(CLM 151) the post must be

grounded. To increase the

immunity to interference cables

should be run inside the post.

Note:

•This instrument has been built

and tested in accordance with

EN 61010-1 and left the

manufacturer’s works in perfect

condition concerning safety

regulations.

•Malfunctions of the instrument can

be remedied by means of the error

list in chapter 7.3 without

intervention in the instrument.

•Alterations to the instrument are

not allowed and make any

guarantee claim invalid.

•After installing and connecting the

instrument and sensors the whole

measuring system has to be

checked for function.
