Inverter External Alarm
The SP PRO provides an alarm output which can be wired to an external alarm buzzer or light etc. A shutdown
alarm is indicated by a continuous ON condition and an alert alarm is indicated by a slow intermittent ON/OFF
condition. If the SP PRO is shutdown or idle the urgent alarm output is ON.
Alert conditions can be prevented from raising the alarm, via SP LINK.
Environmental Considerations
TEMPERATURE
Your 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 minimum distance of 250 mm around the top and sides plus 200 mm from the bottom is recommended.
HUMIDITY TOLERANCE
Your SP PRO is designed to operate in a humidity range of 0 – 99% non condensing.
INGRESS OF PARTICLES
Your SP PRO has been designed to meet IP rating 43 (Protected against solid objects larger than 1.0mm /
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

The power rating of the SP PRO should be compensated for the effects of altitude by applying the
appropriate derating factor. For example, at 2000m above sea level, 6 kW x 0.85 = 5.1 kW. The altitude
compensated rating is still at 40
°C
.
