Operating Instructions

Non-Contact Safety Switch CES-I-AR-.-C04/C14-…

(Translation of the original operating instructions) 2119563-12-03/20

7. ATEX

Safety switches from series CES-I-AR-.-C04… can be used in potentially explosive atmospheres when equipped with housing

guard AM-C-C04-EX-137528 available as an accessory.
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following

standards:

EN 1127-1

EN 60079-0

EN 60079-11

EN 60079-14

EN 60079-7

EN 60079-31

The safety switch is allowed to be operated only in conjunction with the intended actuator CES-A-BBN-C04-EX-137527 from

EUCHNER and the related connection components from EUCHNER. On the use of different actuators or other connection

components, EUCHNER provides no warranty for safe function.

Safety switches with ATEX rating from EUCHNER are not safety devices as defined by the ATEX Directive.

Important!

In order to achieve the explosion protection stated, all the conditions in the operating instructions

must be met. HIGH RISK product.

Devices with ATEX rating may be operated only with actuators that also have an ATEX rating for

the same zone.

Use connection components and connecting cables from EUCHNER.

The connecting cable must be laid such that it is protected against mechanical damage.

In addition, a mechanical barrier is to be provided on the connecting cable as per EN 60079-14,

section 9.3.9, to prevent flame propagation from the non-potentially explosive atmosphere to the

potentially explosive atmosphere.

= It is essential to mount the housing guard to protect the housing. All the electrical connections must either be isolated

from the mains supply by a safety transformer according to IEC 61558-2-6 with limited output voltage in the event of

a fault, or by other equivalent isolation measures (PELV).

= To prevent electrostatic charging, do not subject the actuator to any processes that generate a large amount of

charge.

Permanently and inseparably connect the actuator to the guard using the non-removable screws supplied.
To prevent electrostatic charging:

Do not subject the switch to any processes that generate a large amount of charge.

Clean only with a damp cloth!
