The IECEx/ATEX certified LA36 (optional) is designed for installation in dust filled atmospheres such as grain
handling facilities, cement plants, saw mills or other dusty surroundings. Please note that the IECEx/ATEX approval
is only for dust, and NOT for gas.
The IECEx/ATEX versions are suitable for applications in Group IIIC, Category 2D. Zone 21 and 22.
IECEx/ATEX
Operation of the device is only valid if:
• The product is used under the conditions described in the installation - and operation instruction
• Ambient operating temperature -25°C to +65°C depending on duty cycle
• Atmospheric conditions: Pressure 80 kPa (0.8 bar) to 110 kPa (1.1 bar); and air with normal oxygen content,
typically 21% v/v
• Since the signal and power cables are not UV resistant they need to be shielded against UV light, e.g. daylight
or light from luminaries
• The connection between the actuator and the rest of the machine/device shall be conductive,
and furthermore the application shall be grounded in order to remove any Electro Static Discharge. This counts
for both of the actuator’s fixation points (Back Fixture and Piston Rod Eye)
• Safety and operation instructions are accessible and followed
• Not to be opened in areas with dust, and never by unauthorized personnel
• The production of IECEx/ATEX actuators require quality management systems and auditing.
Therefore, only LINAK A/S is allowed to produce, modify or repair actuators in order to sustain the approval.
No changes are to be made on the actuator after delivery
This manual is part of the equipment. The manufacturer keeps the right to modify specifications without advanced
notice. Keep this manual for later use.
Warnings
If the following is not complied with, the IECEx/ATEX certification will not be valid:
• Actuator specifications must be complied with
• If the actuator has no built-in current cut-off, one must be mounted
• Only IECEx/ATEX approved cables are to be used *
• The power supply/signal cables for the actuator must be terminated in a safe location or alternatively by use of an
Ex terminal box certified for special conditions for safe use
• Only special educated LINAK employees is allowed to change or mount IECE/ATEX approved cables.
• Afterwards It is crucial that the tightness is verified before the actuator is powered up.
