and base. When assembling them, pay attention to the mating number (QA code) in
order to assure the protection rating in a hazardous location.
Please read the operation manual and wiring diagram carefully before installation.
Verify that the supply voltage is in accordance with the data on the nameplate to
prevent short circuit or damage to the electrical/electronic parts caused by incorrect
power input.
Turn power off before wiring or maintenance.
There are grounding devices both inside and outside of the actuator. The ground
wires should be connected properly.
The metal plugs in the conduit entries are for transport only. For long term
protection appropriate flameproof cable glands and power cables must be fitted.
These must withstand a minimum temperature of 105°C (221°F). Please refer to
section 1.2.3
To avoid functional failure caused by a static load, do not touch any components on
the PCB with metal tools or bare hands.
Use proper cable glands in order to seal the conduit entries correctly. Don’t mount
the actuator with conduit entries in upright position in order to prevent water
ingress.
After manual operation, the actuator shall be returned to its unloaded position by
handwheel before electrical operation of the actuator.
The actuator should be installed in an upright or horizontal position. Do not mount
upside down or below the horizontal position.
Periodically inspect the actuator enclosure to prevent dust from accumulating.
Perform below inspections prior to installation. The actuator may not be used if any
of the below items is unqualified.
Check the actuator markings and certificate number in order to check if it
does comply with the intended application.
All parts of the housing must be assembled and fastened in the right
manner.
USE FASTENERS WITH YIELD STRESS ≥ 700MPa.
All the explosion-proof parts may not show cracks or functional defects.
