6.3.6 Installation Wiring
Route cabling through the most appropriate conduit entry
making sure that cables will not foul on the cover assembly
or internal components after refitting. Refer to the actuator
wiring diagram for connection details.
Wire type must meet local and certifying agency (FMC,
FM, IEC Ex, ATEX, etc) requirements and have a minimum
temperature rating of 88 °C.
Terminate the power, control and indication wiring with
appropriate ferrules. Connect wiring to the terminal block
connectors. Ferrules for power connector must be Pheonix
Contact AI 2,5 - 8 or AI 1,5 - 8 series ferrules or equivalent
with a temperature range of -40 to +105
º
C (+40 to +221 °F),
a minimum current rating of 5 A across the temperature
range and approved for field wiring purposes. Take care
to route the wiring away from the spigot housing on the
actuator body.
18 AWG wire is recommended for remote control and
indication connections is with the RIRO option.
WARNING:
Ensure the power supply voltage
matches that stamped on the actuator nameplate.
CMA is configured at the factory for use with one of the
following power supply voltages:
Single-Phase
50 Hz / 60 Hz
110, 115, 120, 208, 220, 230, 240 VAC
DC
24 VDC Only
Supply voltage fluctuations not to /- 10% of the nominal supply
voltage.
Supply frequency tol/- 10%.
6.3.7 Fuses
The DC fuse is a 10 amp, 250 volt, type 3AG. The AC fuse is
a 5 amp fuse which is not serviceable. (Rated to supply 500
watts at 110 volts, which is twice the output power of the
supply).
6.3.8 Relays
Each relay features Normally Open (N/O) and Normally Closed
(N/C) volt-free contacts. Due to the constraints of the Low
Voltage Directive, the maximum allowable voltage that can
be applied to the relay terminals is 150 VAC. For DC the
maximum voltage that can be applied is 30 VDC.
Rated Current is 3 A.
6.3.9 CPT Feedback
The Loop-powered transmitter provides 4 to 20 mA signal
that corresponds to position. Loop supply is 24 VDC nominal
(18-30 VDC max).
6.3.10 Demand
The 4-20 mA command signal is used to control actuator
position.
