2.3 checks to Be perforMed Before
installation
• Make sure the valve to be motorized is the
appropriate one for coupling to the actuator�
• The electrical supply cables must be suitable
for the power rating (see the test certificate
that comes with the actuator)�
• Gather the right tools for the assembly and
for setting the actuator controls�
If a long storage period has occurred, before
reinstalling the actuator, please:
• Check the status of the O-ring seals.
• Check the installation of the plugs or cable
glands on the cable entries�
• Check whether the enclosure covers or the
actuator body are cracked or broken�
• Check the oil level in the actuator and top up
if necessary�
• Put the batteries back into place
(see paragraph 11�3, Maintenance - Lithium
battery change)�
3� INSTALLATION
3.1 workinG condition
The standard actuators are suitable for the
following environment temperatures:
-30°C +85°C (-22°f to +185°f)
Special versions are available for extreme
environment temperatures:
-40°C +70°C (-40°f to +158°f)
-55°C +70°C (-67°f to +158°f)
note:
only for Ex d or Ex d e versions, for
ambient temperature range, see the specific
attached addendum�
iMportant
Check the "temperature environment range"
embossed on the nameplate, for the correct
utilisation with respect to the environment
temperature.
3.2 couplinG Block: disasseMBly froM
the actuator
The bushing is delivered already assembled to
the drive sleeve, even when it is unmachined�
In order to perform the necessary machining,
remove the bushing from its housing� Remove
the fixing screws from the coupling block�
Actuator view from the coupling side, with the
block separated from the gearbox� Do not lose
the seal ring between the coupling block and
the gear reduction unit�
