2.8.11 Overload protection indicator: (OLP)
When
OLP
is indicated on the display one of two conditions has occurred as follows:
a) For an overload condition approximately 110-120% of the WATTS rating of the unit and lasting up to
around 1 minute, an audible alarm will sound and the unit will continue to deliver power directly to the load.
If the overload condition continues the unit shuts itself down.
b) For a larger overload condition the unit shuts itself down immediately.
In both cases it is necessary to restart the unit once the overload has been removed.
In all of the above cases, if an AC utility supply is connected and the AC input breaker switched ON the load will be
automatically be transferred to the utility supply.
2.9 Cooling Fan Operation
The cooling fan management system monitors both the output power and internal temperature of the unit.
The fans will not normally run if the output power is less than 300W, unless the internal temperature exceeds recommended
norms.
In the event that the ventilation openings are obstructed the unit will enter over temperature protection mode (OTP) and
the cooling fan will continue to operate in order to reduce the internal temperature to a safe operating level. Once this
has been achieved the unit will turn on automatically.
3. Maintenance
Scimitar 3000 Series inverters require only minimal maintenance for reliable operation.
The exterior of the unit should be cleaned down periodically with a dry cloth to prevent accumulation of dust and dirt,
paying particular attention to the ventilation openings.
Also, the DC input terminal connections should be checked to ensure that they are sufficiently tight.
4. Troubleshooting Guide
WARNING!
Do not open or disassemble the inverter. Attempting to service
the unit yourself may result in a risk of electrical shock or fire.
Also, the warranty will be void in the event that any seals have
been broken or tampered with.
Scimitar 3000 Series inverters are designed to comply with all relevant EMI Regulations so long as they have been
correctly installed. If incorrectly installed interference with other electronic equipment in close proximity may occur.
• Make sure that the chassis ground lug at the rear of the unit is solidly connected to the ground system of the rack or
cabinet in which it is installed.
• Keep the cables between the battery or other DC source and the unit as short as possible and twist them together about
2 to 3 twists per foot. This will minimise radiated interference from the cables.
