The Series 18H Vector Control is thoroughly tested at the factory and carefully packaged
for shipment. When you receive your control, there are several things you should do
immediately.
1. Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered your control.
2. Verify that the part number of the control you received is the same as the part
number listed on your purchase order.
3. If the control is to be stored for several weeks before use, be sure that it is
stored in a location that conforms to published storage specifications. (Refer to
Section 7 of this manual).
The location of the 18H is important. It should be installed in an area that is protected
from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and
vibration. Exposure to these elements can reduce the operating life and degrade
performance of the control.
Several other factors should be carefully evaluated when selecting a location for
installation:
1. For effective cooling and maintenance, the control should be mounted vertically
on a flat, smooth, non-flammable vertical surface. Table 3-1 lists the Watts
Loss ratings for enclosure sizing.
2. At least two inches clearance must be provided on all sides for air flow.
3. Front access must be provided to allow the control cover to be opened or
removed for service and to allow viewing of the Keypad Display. (The keypad
may optionally be remote mounted up to 100 feet from the control.)
Controls installed in a floor mounted enclosure must be positioned with
clearance to open the enclosure door. This clearance will also provide
sufficient air space for cooling.
4. Altitude derating. Up to 3300 feet (1000 meters) no derating required. Above
3300 ft, derate the continuous and peak output current by 2% for each 1000 ft.
5. Temperature derating. Up to 40 C no derating required. Above 40 C, derate
the continuous and peak output current by 2% per C. Maximum ambient is
55 C.
