The cabling specifications depend on the type of communication interface to be
used.
The QT250 and QT800 control box has five threaded M20 holes for cable glands.
When ordering it is important to consider factors like cable type and size, as the
cable glands have a limited cable entry range. Eltorque standard cable glands can
accommodate a cable between 8-14 mm/0.32 – 0.55 in.
To maintain the Eltorque actuator’s IP encapsulation, it is important to use the
correct rated cable glands, see Table 5 on page 19 and chapter 4.5 on page 36.
The actuators have an EMC class A approval according to DNVGL– CG-0339
without the use of EMC glands. They are therefore by default delivered with non-
EMC glands. If you require EMC glands, please notify your sales contact when
ordering.
The default glands for the different communication interface boxes and ordering
information is given in Chapter 8.
If your actuator cannot be installed immediately, it must be stored it in a dry
place until you are ready to install and connect cables. The actuator does not
come prepared for long time outdoors storage when arriving from Eltorque.
Details on storage temperature is found in Table 5: System performance
parameters for QT250 and QT800 actuators on page 19.
If the actuator can be mechanically installed, but not cabled, please ensure that
all glands and gland holes are thoroughly tightened to avoid ingress of moist.
The actuator’s IP rating is not valid until correctly installed.
Eltorque cannot accept responsibility for deterioration caused on site if the
actuator has been opened in ways not described as required in this manual. In
principle, the product should be powered within three years after production to
prevent components from derating. All actuators are thoroughly tested before
shipping to give trouble-free operation, if installed and commissioned properly.
