Mechanical Assembly

The following steps defines a recommended procedure for fitting TrustedTM chassis and accessories into a 19” rack.

1. Mount the Trusted Shelves require T8247 support brackets to be fitted first and secured by fitting the first power shelf with M5 x 12 Pan Head Taptite screws and large plain and crinkle washers through the support brackets. The power shelf must then be secured to the support bracket using four M3 x 6 slotted cheesehead screws or similar with a plain washer.

2. Mount the Trusted height above and below each controller and expander chassis must be provided to allow the installation of fan trays and vents. The chassis are secured in position using M5 x 12 Pan Head Taptite screws and large plain and crinkle washers through the inner pair of holes on each chassis mounting flange.

3. Mount a Trusted ears using 4-off M5 x Pan Head 12 Taptite screws, crinkle and M5 plastic cup washers. Fan tray units must be fitted AFTER the module chassis to avoid fouling of the chassis power connector.

Power Supply (T8240) into the swingframe as required. The T8240 Power

Controller and Expander Chassis into the swingframe as required. 2U of rack

Fan Tray Unit above each chassis. Fixings are through the fan tray grille and

4. Check the alignment of the chassis and fan tray units on the front of the swingframe.

5. Fit plastic facia ears over the mounting ears of each module chassis. Fixings are M5 x 12 Pan Head Taptite screws and crinkle washers.

6. Fit blanking plates to mask off unused rack space.

Swingframe

1. If a swingframe is used, it is possible to fit equipment to the side of the assembly. Fit 5-off 220mm trunking brackets to the handle side of the swingframe. Fixings are M5 x 8 Pan Head Taptite screws with large plain and crinkle washers. Example 220mm and 60mm brackets are shown right.

2. Fit 80W x 60H trunking to the brackets fitted in the above step. Fixings are M5 x 8 Pan Head Taptite screws with large plain and crinkle washers. The rear edge of the trunking should align with the rear edge of the brackets.

3. Fit a busbar to the trunking brackets, for DC distribution.

Note: The busbar should be mounted as close as

possible to the power supply that is supplying it. The length of the busbar is determined by the requirements of the system. This may result in additional trunking brackets being required.

When determining the length of busbar required, note the following:

a For output field power, each output Versatile

Field Termination Assembly (VFTA) and each Field Termination Assembly (FTA) will require five busbar terminations.

b PSU to busbar feeds will require three busbar terminations.
