7 Installing Power Cables

7 Installing Power Cables

The chapter describes the procedure to fit:

the earth cablr to the racksthe 48/60 Volts DC from the power cabinet to the racks

Verify that the circuit breakers are opened at the power cabinet

Check the fuse ratings (see SPP 27)Measure the voltages at the power cabinet , make sure the values are inthe specified range

Check that the rack breakers are OFF

Ensure that the rack is delivered in 3-wire system If it’s not the case, change itbefore apply this procedure

Install the Power Bus

Cables in the Cable

3 Fasten the cables to the cable tray every 0.50 m using tie wraps.

Mark the following text on cable (factory mounted clip) at fuse holder side:the number of the BSC on site:

BSC 01 for BSC number 01BSC 02 for BSC number 02

7 Installing Power Cables

the type of cable:

BAT A for the -48 VBAT B for the -48 VBAT RET for the O VES/SG for earth (green/yellow or black cable)

The power cabinet must be previously labeled by the customer

The number of the BSC is given in the site documentation; it does not depend

of the product generation

The ground black cable must be marked by yellow/green adhesive tape

Connect the Racks to

Power Bus

1 Remove the outer cable insulation (if the cable is double insulated)

2 Fit the cable clamps on power bus (to achieve good contact, do not remove

the conducting grease)

3 Tighten the nut correctly.
