2.0 Safety

2.1 Limitation of liability

This chapter provides an overview of important safety pre-

cautions and information necessary for safe and trou-

ble-freeinstallation,operationandmaintenance.

DisregardingthisManualandsafetyprecautionsspecied

therein may result in considerable danger and possible seri-

ous injury or death.

2.1.1 Intended use

The actuator has been designed and built exclusively for its

intended purpose as described in these instructions.

WARNING

Risk from misuse!

Any utilization of this actuator beyond its intended purpose may

lead to potentially hazardous situations.

Therefore:

• Strictly adhere to all safety precautions and instructions in this

manual.

• Donotallowthisactuatortobesubjectedtoweatherconditions,

strongUVrays,corrosiveorexplosiveairmediaaswellasother

aggressive media.

• Donotmodify,retoolorchangethestructuraldesignorindividual

components of the actuator.

• Never use the actuator outside of the technical application and

operational limits.

Anyinjury,damageorlosscausedbyviolationofthesein-

structions will be the responsibility of the customer.

2.2 Responsibility of the

owner and processor

The actuator is designed for personal use and is also used

in commercial applications by owner or processors.

The processor is the contracting partner of the reseller or

the manufacturer. The processor installs the actuator in a

complete system (application).

The owner of the system is therefore subject to require-

ments of the Occupational Health and Safety Act.

InadditiontothesafetyinstructionsinthisManual,the

owner or processor must do the following concerning these

safety and acci-dent prevention guidelines and environmen-

tal precautions regulations applicable to the site of the sys-

tem’s installation:

• Inform themselves of applicable industrial safety precau-

tions and determine additional hazards that arise due to

thespecicworkingconditionsprevailingatthesitewhere

the actuator is installed using risk assessment. The risk

assessment must be implemented in the form of work in-

structions for the actuator operation.

• Conrmthattheworkinstructionscreatedforthesystem

including the actuator satisfy current legal requirements

and must alter the instructions if they don’t.

• Clearly regulate and specify the responsibilities for instal-

lation,operation,maintenance,andcleaning.

• Ensure that all employees who deal with the actuator have

read and understood this Manual.

• Provide personnel with the required protective equipment.

Inaddition,ownermusttrainpersonnelatregularintervals

and inform personnel of the hazards.

Inaddition,ownerorprocessorsmustensurethattheactua-

tor is in an adequate working condition. They must do the

following:

• Ensure that the maintenance intervals described in these

instructions are complied with.

• Have all safety devices inspected regularly for function and

completeness.

WARNING

Risk from misuse!

AnImproperinstallation,operationandmaintenancecanresultin

seriousinjury,deathorpropertydamage.

Useonlyqualified,instructed,ortrainedpersonnel(asdescribed

below)whohaveread,understandandfollowtheseinstructions.

2.0 Safety

2.2.1 Qualications

Thefollowingqualicationsarespeciedfordierentareas

of activity listed in the Manual.

• An instructed person (Operator)

has been instructed by the customer in an orientation ses-

sion on the assigned tasks and possible dangers in case of

improper behaviour.

• Qualiedpersonnel

basedontheirprofessionaltraining,know-howandexperi-

ence as well as knowledge of the applicable standards and

regulations is able to perform assigned work activities and

to detect and avoid possible dangers on their own.

• A professional electrician

basedonhis/herprofessionaltraining,know-howandex-

perience as well as knowledge of the applicable standards

and regulations is able to perform work on electrical sys-

tems and to detect and avoid possible dangers on his/her

own. The professional electrician has been trained for the

special location where he/she works and knows the rele-

vant standards and regulations.

Only persons who are expected to perform their tasks reli-

ably are permitted as personnel. Persons whose reaction

capabilityisimpaired,e.g.throughdrugs,alcoholormedi-

cation,arenotpermitted.

2.2.2 Specic dangers

The following section lists the residual risks that have been

determined by the risk assessment.

• Heedthesafetyinstructionslistedhere,andthewarnings

insubsequentchaptersofthisManual,toreducehealth

hazards and to avoid dangerous situations.

DANGER

Danger to life caused by electric current!

Touching conductive parts causes a direct danger to life. Damage

to insulation or individual components can cause danger to life.

Therefore:

• Intheeventofdamagetoinsulation,switchothepowersupply

immediately and have the parts repaired.

• Work on the electrical system must be carried out only by profes-

sional electricians.

• De-energize the machine for all work on the electrical system.

• Beforemaintenance,cleaningorrepairwork,switchothepower

supply and perform lockout procedures so it cannot be turned on

again.

• Donotbridgefusesormakethemineective.Whenchanging

fuses,makesureyouusethecorrectamperage.

• Keepmoistureawayfromconductiveparts.Ifyoudon’t,thiscan

cause short circuit.

WARNING

Danger of injury caused by moving components!

Rotating and/or linearly moving components can cause severe injury.

Therefore:

• Donotworkonorplaceanyofyourbody,hands,orarmsnear

moving components.

2.3 Safety equipment

WARNING

Danger due to malfunctioning safety equipment!

Forsafeoperation,besureallsafetyequipmentisingoodworking

order.

Therefore:

• Always check functionality of safety equipment according to the

maintenance plan.

• Never disengage safety equipment.

• Safetyequipmentmayneverbeby-passedormodied.

Integration in an emergency-stop system

required (for certain applications)

The actuator is only intended for installation into an an appli-

cation or system. It does not have its own operating control

elements and does not have an independent

emergency-stop-function.

Installtheactuatorsothatitispartofanemergencyshut-o

system and can be stopped if necessary.

Theemergencyshut-osystemhastobeconnectedinsuch

a way that a disruption of the power supply or the reactiva-

tion of the power supply after a power disruption cannot

cause a hazardous situation for persons and objects.

Theemergencyshut-osystemsmustalwaysbefreelyac-

cessible.

NOTE

The processor decides which applications require the

installation of an emergency shut-off system.

CAHB-20 series

The following safety features may have been

installed:

A thermal switch is integrated into the motor inside to pre-

vent damage from overheating. If overheating occurs when

theactuatorisoperating(overspecication),theswitch

wouldbeactivated,thepowerwouldbecut-o;afterthe

temperaturefallsbelowthethreshold,theswitchwillrestore.

CAUTION

Topreventdamagefromoverheating,donottrytooperate

actuator until its temperature has fallen below the threshold for

the switch to operate.

A driving screw nut converts the rotation of the gear unit into

linear motion. If an overload occurs when the actuator is

operating,aballdetentclutchwilloperate,thusstoppinglin-

ear motion.

E design only

CAUTION

Continued operation of the clutch can result in overheating and

damagetothelinearactuator.Ifclutchactivates,switchoffpower

immediately.

2.4 Changes and

modications on the

actuator

To avoid hazardous situations and to ensure optimal perfor-

mance,donotmakeanychangesormodicationstotheac-

tuatorunlesstheyhavebeenspecicallyauthorizedby

Ewellix.
