Introduction
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
section of this manual on page 2.
Please report any damage or missing parts to your supplier immediately.
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). When installed in an enclosed space, ensure that
there is adequate ventilation. The SP PRO must be located in a place away from electrolyte and
corrosive aerosols.
The SP PRO must be installed in a fixed installation. The SP PRO is not suitable for mobile
applications that are subject to vibration or g-forces greater than 2g. The SP PRO must not be
transported after installation into a containerised, cabinet or similar system if they could be subject
to excessive g-forces.
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. A backup 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 may start automatically
The SP PRO automatically starts and / or restarts and may restore power at any time. If a fault or
overload is detected the SP PRO will shut down and may automatically attempt to restart at varying
intervals of up to several hours.
Backup Generator may start automatically
The SP PRO automatically starts and / or restarts a backup generator (when a Grid Fail / Generator
Backup option is installed). If a fault or overload caused the SP PRO to shut down, then it will
automatically attempt to start and restart the backup generator.
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.
•
Batteries are capable of sourcing extremely high output currents. Short circuit or high overload currents
can be extremely hazardous and cause high current arcs, burns and explosions.
•
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 in place.
•
System battery voltages of 60V or greater are to be treated as a hazardous voltage.
