X2.3.2 Actuator Termination
Feedback termination at the actuator for the D size Power Module
is the same as for the other size modules (section 5.2.2).
X2.4 Module Cable
A thermostatically controlled cartridge heater and solenoid power
(optional; only connected on spring fail units) are installed in the
power module. The module cable supplies power for the heater
and solenoid and contains the actuator ground.
!
SHOCK HAZARD
Hazardous voltage levels are present in the module cable.
Insure that the electrical power to the drive is off before
connecting the module cable.
X2.4.1 Enclosure Termination
The black and white wires of the triad are connected to the two
position terminal block. Connect the cable by following drawings:
D97103 and A97101 for the ½D, D97096 and A97099 for the D or
D97097 and A97100 for the 2D. The green/yellow wire of the triad
should connect to the green ground screw on the metal backplane.
X2.4.2 Actuator Termination
The cable is terminated in the junction box as shown in drawing
S96502.
X2.5 User Connections
The standard electric power is 240 VAC -20/+10% for D and 2D
modules,1 phase. 120 VAC power is available by using the optional
separately mounted transformer.
The standard electric power for the ½D module is 120 VAC -20/+10%,
1 phase, drawing D97103.
The incoming control signal must be wired. The connections for
auxiliary boards (position transmitter, etc.) are shown in Appendix C.
On 2D size units, there is a junction
box located at each module. One
module cable is required. The
heater power should be connected
between boxes and the solenoid
will only be installed on one mod-
ule.
A cable consisting of 3 twisted
pairs and a triad is supplied as the
module cable. Only the triad and
blue pair are used. Cutback the
remaining wires ensuring no shorts
are present.
