1 General Information
Failure to follow safety instructions may cause serious injury, equipment damage, or voided
warranty.
1.1 Safety Instructions
Installation, maintenance and repair works must be performed by trained personnel.
The handling shall follow the safety and warning instruction contained in this manual.
The user should read and follow instructions contained in this operation manual included with
the product. Failure to do this may result in damages and void warranty. Sun Yeh will not be
liable for damages due to operator negligence or misuse.
Local health and safety legislation shall be complied with.
In a few cases, the surface temperature may exceed 60°C (140 ℉). Please check the surface
temperature before operation, using an appropriate thermometer and wearing protective gloves
before operation.
1.2 Installation Notices
All setting of opening the cover must be made in the safe place, prevent the spark from
making the possibility of explosion.
Operating by handwheel: Do not use excessive force when operating the handwheel as this
can damage the actuator or valve.
1.2.1 General
DO NOT install in ambient temperatures that exceed 70 °C (158 °F).
DO NOT, under any circumstances, remove the cover of the actuator while in a hazardous
location when the power is still live inside the actuator. This could cause ignition of a
hazardous atmosphere.
DO NOT, under any circumstances, use an explosion-proof electric actuator in a hazardous
location that does not meet the specification which the actuator was designed for.
Mount, test, and calibrate actuators in non-hazardous location.
When removing the actuator, care must be taken not to scratch, scar or deform the flame
path of the cover or base of the actuator. That will negate the protection rating of the
enclosure in a hazardous location.
The explosion proof electric actuator is shipped with mating surfces of the cover and base.
When assembling them, pay attention to the mating number (QA code) to assure the
protection rating in a hazardous location.

Please read operation manual and wiring diagram carefully before installation.
Verify that supply voltage is in accordance with the data on nameplate to prevent short
circuit or electrical/electronic parts damage caused by incorrect power input.
Turn power off before wiring or maintenance.
There are grounding devices both inside and outside of the actuator and the ground wires
should be connected properly.
The metal plugs in conduit entries are for transit only. For long term protection fit suitable
flameproof cable gland and power cable should be with a minimum withstand
temperature105 °C (221°F). Please refer to 1.2.3 (P.3).
To avoid functional failure caused by static, do not touch any components on the PCB with
metal tools or bare hands.
Do not parallel wire multiple actuators together without using an extra relay.
Use proper techniques when installing conduit and properly seal the connection. Do not
mount the actuator with conduit entries in upright position to prevent condensation from
entering the unit.
Actuator should be installed in an upright or horizontal position. Do not mount upside
down or below a horizontal position.
Periodically inspect actuator enclosure to prevent dust from accumulating.
Perform below inspections prior to installation. Not allowed to adopt if any item is
unqualified.
Check the marking and certificate number to see if it conforms to the indicated
application.
All the parts of the housing are assembled in the right manner and fastened.
USE FASTENERS WITH YIELD STRESS ≥ 700MPa.
All the explosion-proof parts should be made without cracks or functional defects.
1.2.2 CSA Certification Considerations
KEEP COVER TIGHT WHILE CIRCUITS ARE ALIVE.
AFTER DE-ENERGIZING, DELAY 10 MINUTES BEFORE
OPENING THE COVER.
SEAL REQUIRED WITHIN 18 INCHES (450 mm) OF ENCLOSURE (for Divisions
only).
SEAL REQUIRED WITHIN 2 INCHES (50 mm) OF ENCLOSURE (for Zones only).

3.4 Actuator Selection
3.5 Sizing
The actuator shall be sized to ensure that its torque output meets the load requirements of valve
and its ability to overcome the required duty cycle of application (As a MINIMUM, a 30% safety
factor is suggested for the calculation of torque requirement).
a.
If the maximum torque of 5” valve is 80 Nm 80 × 1.3 (safety factor) = 104 Nm
104 Nm < 150 Nm (OME-3) OK!
104 Nm > 90 Nm (OME-2) Not OK!
b. In cases where the actuator does not fit directly onto the valve, a mounting kit is required. Please
ensure the bracket and coupling are properly designed and manufactured to withstand the torque
output of the actuator.
