Second step: If the above is not accepted by the customer due to extra power
consumption, ask for customer approval and install the external power supply unit.
Notes on Using the External PSU
 When using the external PSU, confirm that the LED is lit before turning on the main
power. If the main power is turned on while the LED is not lit, this will result in an SC.
 The LED will not light up if the breaker switch is turned off or if the timer is set to off.
 Refer to the last section of this document for instructions on how to switch supply
source between Pro C900 / Pro C901 and the external PSU.
