24 Installation Guide APC Silcon 480kW 400V UPS

990-4053

External Connection

To add card slots, you can daisy-chain the APC Silcon Triple Chassis with the standard Triple

Chassis (AP9604) management peripheral, installing the APC Silcon Triple Chassis closer to

the UPS.

4.7.4 Powering the APC Silcon Triple Chassis

The APC Silcon Triple Chassis supplies power to the installed management peripheral cards

and to the Monitoring port, allowing you to power multiple management peripherals.

4.7.4.1 AP9604S Power Considerations

The AP9604S model of the APC Silcon Triple Chassis receives its power from the UPS through

the power connector of the Silcon UPS cable. If the total current required by all the installed

management peripherals exceeds 500 mA, you must use a 24 VDC power adapter. To find out

whether you need additional power, see “Determining power requirements”.

4.7.4.2 Power Adapters

APC offers two models of 24 VDC power adapter.

• The standard adapter (AP9505) can provide an additional 400 mA.

• The universal adapter (AP9505i) can provide 850 mA.

4.7.4.3 Using a Power Adapter

To use the adapter, plug it into a protected power outlet and into the Optional Power port of

the APC Silcon Triple Chassis.

4.7.4.4 AP9604SR Power Considerations

The AP9604SR model receives its power from the UPS through the supplied 24 VDC universal

adapter. The total current required by your management peripherals must not exceed the 850

mA limit of the power adapter. See ““Determining power requirements”.

4.7.4.5 Determining Power Requirements:

To determine the total amount of current required by your management peripherals, add the

individual current requirements for each management peripheral to be installed with the APC

Silcon Triple Chassis to the current requirements of the chassis itself. Refer to this table

NOTICE!

If the power adapter loses power because of a UPS shutdown, its attached management

peripherals may not operate properly, thus adversely affecting the UPS and its protected

equipment.
