Installation- G e n e r a l

Re q u i r e m e n t s

C h a p t e r T h r e e

The SP PRO must only be installed by suitably qualified personnel.

Many procedures covered in the INSTALLATION sections of this manual have inherent risks. Whilst the SP PRO is designed to be safe, including safety features never before found in an inverter (such as Earth / Neutral bond monitoring), the voltages connected to or generated within the SP PRO are hazardous and potentially fatal.

It is the responsibility of the installer to ensure the installation and all the wiring is carried out according to all safety standards that are applicable to the installation. The wiring diagrams and installation instructions are given as a guide only and compliance to appropriate standards is the responsibility of the installer.

The following section provides general installation instructions for the

SP PRO

. For information on specific configurations please refer to the “Installation-Specific Applications” Section in this manual and the relevant installation guide supplied with any required installation options.

All installation notes including this manual can be downloaded from the Selectronic web site at: www.selectronic.com.au

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

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 .

Preparation

The selection of a suitable site and good preparation is essential in getting optimum performance from the

SP PRO.

SP PRO Inverter performance is dependant upon the environmental operating conditions, in particular ambient temperature and ventilation. In addition safety aspects must be considered, such as:

• Restrict access to authorised personnel only.

• Consideration of maintenance of ambient temperatures to ensure performance within product specification.

• Positioned away from heat producing devices such as generators.

• Adequate ventilation, adhering to the minimum clearances required for adequate heat dissipation.

Minimum 150 mm clearance from top, bottom and sides.

• In a covered location away from direct rain. The SP PRO has an environmental rating of IP43 which makes it unsuitable for water spray that is greater than 60 deg from the vertical or greater than 0.7 litres per minute.

• In a location shaded from direct sunlight.

• Away from any explosive gas.

• Rodent Proof.

• In a clean environment away from dust, iron filings, workshop pollutants and other small particles.

• Enough room to remove the cover.

• The provision of infrastructure for monitoring - example data cables

The SP PRO should be installed in a separate area to the battery system (where used). The battery bank can emit explosive gas(hydrogen) and this must be vented outside and away from the SP PRO. The battery system should not be accessible by the user.

When batteries are used in the system is recommended that the installation be in lockable area with a separating partition or enclosure for the battery bank.
