Safety

SAVE THESE INSTRUCTIONS– This manual contains important instructions for

the Silicon Energy Solar Inverter Models SiE5300, SiE4900, SiE3840 & SiE2900

that shall be followed during installation and maintenance of the Silicon Energy

Solar Inverter [hereafter SiE Inverter(s)].

Safety Precautions/Safety Notes

Only trained qualified electrical personnel are to perform the electrical installation,

wiring, opening and repair of the SiE Inverters. Even when no external voltage is

present, the SiE Inverters can still contain high voltages and the risk of electrical

shock.

The temperature of the heat sinks outside of the device can reach over 70°C (158°F)

in normal operation (Ambient temperature rating: 55°C / 131°F). There is the risk

of burn injury when these parts are touched.

The following general safety precautions must be observed during all phases of

operation, service, installation and repair of this device. Failure to comply with

these precautions or with specific warnings elsewhere in this manual violates safety

standards of design, manufacture, and intended use of the device. The manufacturer

assumes no liability for the customer’s failure to comply with these requirements.

Safety Symbols

To reduce the risk of injury and to ensure the continued safe operation of this

product, the following safety instructions and warnings are marked in this manual.

Warning, risk of electric shock

Presents safety information to prevent injury or death to users and/or

installers.

Earth ground symbol

Caution (refer to accompanying documents)

Presents information to prevent damage to this product.

General Safety Precautions

Personnel must remove all conductive jewelry or personal equipment prior

to installation or service of the device, parts, connectors, and/or wiring.

Trained qualified personnel are required to mount, reconfigure or repair this

device.

Licensed electricians are required to install permanently wired equipment.

Stand on an insulated surface when working on the operating device (i.e.,

ensure that there is no grounding).

Instructions in this manual must be precisely followed and all information

on cautions or warnings must be adhered to.

Use proper lifting techniques whenever handling enclosure, equipment or

parts.

The SiE Inverter must be provided with an equipment-grounding conductor

connected according to local codes and regulations.

The SiE Inverter must be provided with a DC grounding connection

according to NEC and Local Electrical codes. The grounded conductor must

be ungrounded and energized when a ground fault is indicated.

The AC Neutral connection is only for voltage sensing and shall be neither

used to carry currents nor bonded to ground inside the inverter.

These precautions/warnings do not contain all measures pertinent to the safe

operation of the device. If special problems arise which are not described in

sufficient detail for the purposes of the buyer, contact your specialized

dealer or technician.

Safe Installation and Operation

Installation of the device must be in accordance with the safety regulations

(e.g., UL1741) and all other relevant national or local regulations. Correct

grounding and short circuit protection must be provided to ensure

operational safety.

Read all instructions and cautionary remarks in the manual before

installation.

Switch off the circuit breakers before installation and wirings. Avoid

standing water when working on the inverter.

PV arrays will be energized when exposed to light. Cover the arrays with

opaque (dark) material during installation and wiring.

Check both of the AC and DC connections with a digital volt meter prior to

any installation or removal procedures.

Attach the outer cover correctly before switching on the circuit breakers.

Install the inverter out of direct sunlight.

When no external voltage is present; the SiE Inverter can still contain high

voltages and the risk of electrical shock.

Allow at least 5 minutes for the inverter to discharge completely after

disconnecting the AC and DC sources from the inverter.

External heat sinks can reach high enough temperatures in normal operation

to cause skin burn injury when these parts are touched. Pay attention to high

temperature components.

To prevent the risk of fire hazard, do not cover or obstruct the heat sink.

Allow changes in your electrical system to be carried out only by qualified

electricians.

Repair and Maintenance

The SiE Inverter contains no user serviceable parts, except for the fan, the

PV string fuses and the GFDI fuse. Only SILICON ENERGY trained staff is

authorized to carry out internal repair and maintenance of the unit. Please

return the device for repair and maintenance for faults caused by parts other

than the fan and the fuses described above. For maintenance and

replacement of the fuses, please refer to the section 5.4.

WARNING!

DO NOT make alterations or tamper with the assembly in the

inverter without manufacturer’s authorization unless specified

elsewhere in this Manual. This may result in injury, electric

shock, or fire and void the warranty.

Wiring the inverter

Input/Output Terminals: Use wire size #10 AWG to #6, 90°C (194°F)

Copper Wire.

Reconfirm that all connections have been performed properly and all

screws are properly tightened.

WARNING!

All electrical installation and the wiring methods shall be done

in accordance with the local and National Electrical codes

ANSI/NFPA 70 and should follow the important safety

instructions in this manual.

WARNING!

Make sure that you use suitable connecting cables for both the

AC and DC wiring. The cable must be adequately dimensioned

and suitably inert to temperature fluctuation, UV radiation

and other possible hazards.
