3.1 Unpack and Inspect
Remove all packing materials and inspect the Controller. If the Controller is damaged, notify your supplier and the
carrier in writing within three days; state the Item Number of the Controller together with your order number and
your suppliers invoice number. Retain all packing materials for inspection. Do not use the Controller if it is damaged.
Check that your package contains the items listed in Table 8 . If any of these items is missing, notify your supplier in
writing within three days.
If the Controller is not to be used immediately, store the Controller in suitable conditions as described in Section 6.1 .
3.2 Fit the Controller
CAUTION
You must allow the correct clearances for air circulation and you must fit the EXC120E Controller onto a
thermally conductive surface. If you do not, the performance of the Controller may be affected at high operating
temperatures.
The Controller can be used on a bench-top or can be fitted in a rack or cabinet. You can operate the EXC120, EXC300
and EXC300M Controllers in a horizontal position or in a vertical position with the front panel at the top. You can
operate the EXC120E Controller in a horizontal position or in a vertical position with the side vents at the top.
When you fit a Controller in a rack or a cabinet, you must allow 15 mm clearance at the sides of the Controller for
air circulation and you must allow 75 mm clearance at the back of the Controller for the cables. Do not obstruct the
cooling-fan on the EXC300 and EXC300M Controllers. The size of the front panel cut-out required and the location of
the front panel fixing holes for the EXC120, EXC300 and EXC300M Controllers are shown in
Figure 6 .
When you fit the EXC120E Controller, you must firmly fit the Controller onto a thermally conductive material, for
example aluminium or steel. The location of the bottom panel fixing-holes are shown in
Figure 7 .
