Power supply output must be low impedance (for example, directly from 

batteries). DO NOT power low-voltage versions of the control from high-voltage 

sources with resistors and zener diodes in series with the control power input. 

The 2301A control contains a switching power supply which requires a current 

surge to start properly. 

To prevent damage to the control, do not power low-voltage versions 

of the control from high-voltage sources. 

High and low voltage models of 2301A Speed Controls are available. Low 

voltage models require a supply of 10 to 40 Vdc, 12 W. High voltage models 

require a supply of 88 to 120 Vac or 90 to 150 Vdc., 12 W. The ac supply may be 

50 to 400 Hz. 

If a battery is used for operating power, an alternator or other battery charging 

device is necessary to maintain a stable supply voltage. 

To prevent damage to the control, make sure that the alternator or 

other battery-charging device is not connected to the control when 

the battery is disconnected from the control. 

Location Considerations 

Consider these requirements when selecting the mounting location: 

· Adequate ventilation for cooling 

· Space for servicing and repair 

· Protection from direct exposure to water or to a condensation-prone 

environment 

· Protection from high-voltage or high-current devices, or devices which 

produce electromagnetic interference 

· Protection from excessive vibration 

· An ambient operating temperature range of –40 to +85 °C (–40 to +185 °F) 

Do not mount the control on the engine. 

Electrical Connections 

External wiring connections and shielding requirements for a typical control 

installation are shown in the plant wiring diagram, Figures 2-4 and 2-5. These 

wiring connections and shielding requirements are explained in the balance of 

this section.
