Caution
• If an external DC supply is not available, a Power Supply Card (model
751313) will be needed. To connect the power cable, refer to Section 6.2
on page 1-24.
• If an external DC supply is available, and you have decided to add an
internal power supply, you must first disconnect the -24 V dc input to
TB2. You need to do this because this input is on the same bus as the
power supply output and it will load the power supply down since the
internal power supplies are adjusted to -27 V dc (enabling the charging
of the battery pack, model 751312). Then connect the power cable
provided to TB3 (the Power Supply Card itself can only be powered via
TB3), refer to Section 6.2 on page 1-24.
