Preparation; Installation; Maintenance; Inverter Or Generator May Start Automatically - Selectronic SP PRO Instruction Manual

Preparation

Whilst every effort has been made to pack the SP PRO in a way that will provide adequate protection,
damage in transit can occur. Please carefully check the packaging and the SP PRO for signs of damage
and for all components mentioned in the "Included in the Package" section of this manual.
Please report any damage or missing parts to Selectronic or your Selectronic Authorised Distributor.
Please retain the original packaging for the safest and most effective method of repackaging if required.

Installation

• The SP PRO requires adequate ventilation, away from hot equipment. Do not obstruct the
airflow passage of the SP PRO case (top and bottom). Ensure when installed in an enclosed
space that there is adequate ventilation.
• The SP PRO must be located in a place away from electrolyte and corrosive aerosols.
• The SP PRO contains arcing contacts so must not be located near explosive gas mixtures
such as hydrogen from batteries or diesel fumes.

Maintenance

Ensure that all energy sources are isolated before working on connected wiring. The generator
may start or power may be restored by the SP PRO at any time. Never work on equipment or
investigate a problem without following appropriate safety isolation procedures.

Inverter or Generator may start automatically

The SP PRO automatically starts and/or restarts and may restore power or start the generator
at any time. If a fault or overload is detected the SP PRO will shutdown and may automatically
attempt to restart at varying intervals of up to several hours.

Battery

Batteries are very dangerous. Please read the safety information provided by the battery
supplier.
• Battery acid is dangerous.
• Batteries can emit hydrogen gas, which is explosive.
• Batteries connected in series can produce hazardous voltages.
• Disconnecting a DC power connection (even on one battery cell) can cause dangerous high-energy DC
arcs, which can cause serious burns and eject hot particles, and can be difficult to extinguish.
• Disconnecting a DC power connection (even on one battery cell) can cause renewable sources to
produce large voltages (much larger than the battery voltage) on battery terminals and DC wiring. Such
voltages can be lethal. They can also damage the SP PRO. Only suitably trained and qualified personnel
should disconnect any DC power connection, including battery cell connections, and only with suitable
procedures and safety precautions.
• System battery voltages of 60 V or greater are to be treated as a hazardous voltage.
