The SCE300 actuator is delivered with the drive details and ange as requested by the
customer, and is ready to be installed onto the valve. Only one insert is included in the
actuator package delivered to end users. Refer to Table 9 for the recommended torque for
the mounting base bolts.
NOTICE
Installation in environments with temperatures outside the rated temperature will
invalidate the warranty. Refer to the nameplate to verify the rated ambient temperature.
NOTICE
In case the screws of the cover, of the terminal compartment and of the OM3 must be
replaced, SS Aisi 316 Class A4 grade 80 screw must be used with minimum yield strength
600 N/mm², the screw size is M6 X 25 mm. Other screws used for the assembly of the
other various parts of the explosion proof enclosure shall be a SS AISI 316 Class A4 Grade
70, with minimum yield strength of 450 N/mm

. Every time the main cover, the terminal
compartment cover and the OM3 are reassembled, make sure to tight all the screws with
5 Nm torque.
NOTICE
For the model E171 and 2000 of the SCE300 Series only: during installation, the user shall
take into consideration that the actuator was assessed at a low risk impact energy at 2J.
WARNING
During operation, the temperature of the actuator surface can reach 30 °C (86 °F) above the
ambient temperature. Use proper PPE when handling high-temperature areas of the actuator.
CAUTION
Using fasteners other than the approved type may result in damage to the actuator or valve.
