Figure 72. 120 Vac Inputs and 120/230 Vac Outputs/C445 Power
Notes:
1.
The inputs on the Base Control Module are only used by
this Operation Mode if Fieldwire is selected for one of
the control sources. If Fieldwire is not the Local or
Remote control source, all 4 inputs may be used as
general purpose inputs.
2.
Output 3 may be used as a general purpose output for
this Operation Mode.
3.
If Fieldwire is the Local control source, Input 3 is the
Remote input and 3-wire control is not allowed for this
operation mode. When power is applied to Input 3, the
C445 will be in Remote mode.
4.
If Fieldwire is the Remote control source, 3-wire control
is allowed and Input 3 is the Permissive Input.
5.
Fusing: Although C445 product listings do not require
fusing on the high impedance line voltage measurement
inputs, it may be necessary to provide overcurrent
protection of the supply leads in accordance with
applicable final installation specific local, state and
national electrical codes.
