Checking Rack Installation before Installing Modules

It is a good idea to check the installation before applying power to the rack.

Before Applying Power to the Rack

Step 1:

Clean out dust, metal scraps or other debris from the rack interior.

ETC recommends vacuuming the rack interior before installing modules.

Step 2:

Check for loose connections, bare wires or damaged insulation.

Step 3:

Correct air leaks caused by misaligned or removed panels, empty screw holes,

or conduit openings.

Step 4:

Remove the cardboard protective cover from the top fan grille. Spin the top

cooling fan to be sure it is not obstructed.

Step 5:

Check resistance between phases, Neutral and Earth for short circuits:
a: Phase to Phase; resistance should be 500k ohms or higher
b: Phases to Earth; resistance should be 500k ohms or higher
c: Neutral to Earth; resistance should be very close to 0 ohms
d: Phases to Neutral; resistance should be 500k ohms or higher

Installing Advanced Features (AF) Cards (Optional)

If your rack is an Advanced Features

rack, it should be supplied with AF cards

from the factory. Normally these will be

pre-fitted for you, however if you do need

to fit the cards use the following

procedure:

Step 1:

Address your AF cards using

the DIP switches as shown in

Figure 34

Step 2:

Locate the AF card slots at the

right hand side of the rack

Step 3:

Insert the AF cards into the

slots and push until securely seated, a tangible click occurs when fully inserted.

Installing the Control Electronics Module (CEM3)

Step 1:

Inspect the CEM3 for loose components or other shipping damage.

Step 2:

Slide the CEM3 into the rack.

Step 3:

Push on either side of the CEM3 until it is flush with the front of the rack. Do not

push in the centre as you may cause damage to the display.

W A R N I N G :

RISK OF ELECTRIC SHOCK! Power must be turned OFF when you perform

this procedure.
