Environmental Considerations
TEMPERATURE
The SP PRO is designed for an ambient operating temperature between -20 °C and 60 °C , with a storage
temperature range between –20 °C and 70 °C .
AIR FLOW
For best performance ensure nothing impedes ambient air from being drawn in the bottom of the unit and
that hot exit air is vented away and doesn’t recirculate into the unit. Particular attention must be paid when
installed inside a cabinet or enclosure.
CLEARANCE FROM OTHER EQUIPMENT
A recommended clearance distance of 150 mm around all sides, top and bottom. Particular care must be
taken when mounting near other heat producing equipment.
HUMIDITY TOLERANCE
The SP PRO is designed to operate in a humidity range of 0 – 99% non condensing.
INGRESS OF PARTICLES
The SP PRO has been designed to meet IP rating 43 (Protected against solid objects larger than 1.0 mm /
protected against water falling as a spray at up to 60 degrees from the vertical) i.e. may be installed outside
under cover and is insect and vermin resistant.
Effects of altitude on the SP PRO
Altitude
(m) Derating Factor
@ 40
°C
0, sea level 1.00
1000 0.95
1500 0.90
2000 0.85
The power rating of the SP PRO should be compensated for the effects of altitude by applying the
appropriate derating factor. For example, at 2000 m above sea level, 6 kW x 0.85 = 5.1 kW. The altitude
compensated rating is still at 40
°C .
