Installation Step Comments OK

1.EARTH CONNECTIONS

The AC Earth (PE) and DC Earth (TE) terminals aremechanically connected tothe cabinet chassis.

The Common Positive Bus baris internally cabled to DCEarth (TE); thus the positiveoutput of the rectifiers isconnected to ground (TE),and the negative outputrepresents the 48Vdc supplyvoltage.

If required, you can remove the internal cable that connectsthe positive bus bar to local PE.

2.ACCONNECTIONS

Switch OFF the AC input power (external MCBs), beforeconnecting the cable.

Open the clamps that fasten the cable entry rubber gland.

Shape the cable entry rubber gland with a knife to fit themains cables, and draw the cables into the top of thecabinet. It is recommended to do the same with the loadcables at this time. Fasten the cables with strips to thebrackets inside the cabinet. Do not make the cable slot toowide! Use silicon to make the input hole watertight.

Connect the AC cables, max. 35sq mm(AWG 2), to theterminal block in the top of the cabinet as the labelsindicate. Replace the cable entry clamps. Do not power upthe system until the whole installation is complete.

Connect the external AC ground wire to the cabinets mainProtective Earth (PE) terminal. See

Rectifier Installation Mains Supply Balancing Effect

The Flatpack PRSBsystem may be expanded to a maximum of 10 Flatpack 1500 rectifiers.In order to load the AC supply net evenly similar current load from the 3 phases of themains supply it is advisable to mount the required number of rectifiers in the followingorder:

Figure 4 Rectifier mounting order to load the mains supply evenly.

When possible, mount an equal number of rectifiers on each phase, L1, L2 and L3.

Rectifier Installation Handles and Locking Mechanism

The Flatpack 1500rectifier module is equipped with handles that serve two purposes:

Locking the module into position

Open both handles, insert and plug the module into powershelf. Then lock it into position by rotating the handles upwardsand pushing them firmly home; failure to do so will prevent themodule from making proper contact.

Figure 5 Module with released handles

Pulling the module out

Unlock and release the handles by insertinga small screwdriver into the upper holes,

thus releasing the spring mechanisms. Donot use excessive force. The handles willrelease and pop out. When both handles arereleased, use them to pull the module out.

Do not hold or carry the rectifier by itshandles.
