Finishing Installation
RISK OF ELECTRIC SHOCK! Power must be turned OFF when you
perform this procedure.
Clean out dust, metal scraps or other debris from the rack interior.
ETC recommends vacuuming the rack interior before installing modules.
Check for loose connections, bare wires or damaged insulation.
Correct air leaks caused by misaligned or removed panels, empty screw holes, or conduit
openings.
Remove the cardboard protective cover from the top fan grille. Spin the top cooling fan
to be sure it is not obstructed.
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
Address your AF cards using the DIP
switches as shown in Figure 7.
Locate the AF card slots at the right
hand side of the rack.
Insert the AF cards into the slots and
push until securely seated, a
tangible click occurs when fully
inserted.
Inspect the CEM3 for loose components or other shipping damage.
Slide the CEM3 into the rack.
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.
Inspect each dimmer module for loosened components or shipping damage.
Slide dimmer modules into the rack. If you are installing a mix of module types, consult
the included project drawings for the correct module order.
Push each module into its slot until it is flush with the front of the rack.
