Section 3: Installation
3.5
Electrical Connections
Before powering the actuator check that the supply voltage details on the nameplate
are correct for the receiving plant. Access to terminals for electrical connections and
commissioning is via the terminal cover, since all settings are non-intrusive. The removal of
any other covers without Emerson approval will invalidate the warranty; Emerson will not
accept responsibility for any damage or deterioration that may be caused.
NOTICE
All accessories (including cable glands) must comply with approved specifications for the
site requirements and be certified according to the standard directive.
3.5.1
Plant Requirements
Protection devices (overcurrent breakers, magneto-thermal switches, or fuses) should be
provided at the plant by the administrating customer to protect the mains line in case of
motor overcurrent or loss of insulation between phases and earth.
3.6
Removing the Terminal Board Enclosure
Using an 8mm Allen key, loosen the four screws and remove the cover.
WARNING
Be careful to not damage the joint surfaces of the terminal cover or seal during removal.
CAUTION
Using a fastener other than the approved type may result in damage to the actuator or
valve. Refer to Table 7.
NOTICE
If the screws of the cover must be replaced, a SS AISI 316 must be used with minimum yield
strength of 450N/mm
2
(65,266psi).
CAUTION
Failure to use proper torque values can result in damage to the actuator and/or valve.
