Chapter 2 Installing and Removing Power Components

How to Install or Remove Fixed Configuration Power Components

Required Tools and Equipment

You need the following tools to perform this task:

ESD-preventive wrist strap

Crimping tool and lug specific die

3/8 in. ratchet wrench with 10-mm socket

Torque wrench with 10-mm 6 pt. socket and rated accuracy at 30 in.-lb (3.39 N-m)

Torque wrench with 10-mm 6 pt. socket and rated accuracy at 20 in.-lb (2.26 N-m

Steps

To wire the DC PDU, perform the following steps:

Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the rear (MSC) side of the chassis or a bare metal surface on the chassis.

Step 2 Remove the upper plastic terminal block safety cover (leave the lower safety cover in place; as shown in Figure 2-11). Using a standard Phillips screwdriver, remove the four screws holding the upper plastic safety cover to the wiring terminal block.

Step 3 Use the crimping tool mandated by the lug manufacturer to crimp the lugs to the DC-input cables and the ground cable. For details on lugs, see the “DC Power Systems” section on page 2-6.

The cable should be sized according to local and national installation requirements.

Note The terminal posts are centered 0.63 inches (5/8 inch) (1.60 cm) apart and are M6-threaded. We recommend that you use an appropriately sized 45-degree angled industry standard 2-hole, standard barrel compression lug.

Step 4 Using the 10-mm socket wrench, attach the ground cable to the ground cable terminal. Then use the torque wrench to tighten to a torque of 30 in.-lb (3.39 N-m).

Step 5 Using the 10-mm socket wrench, attach the three negative cables (the red cables as shown in Figure 2-11) and the three positive cables (the black cables as shown in Figure 2-11) to the terminal block. Then use the torque wrench to tighten to a torque of 20 in.-lb (2.26 N-m).

Step 6 Reattach the upper plastic safety cover with a Phillips screwdriver. Insert and tighten the four screws holding the cover to the wiring terminal block.
