Safety Message Types

WARNING

Safety information important for human safety. Warning is used for indicating potentially hazardous situations that can cause serious injury or death.

CAUTION

Caution with symbol is used for indicating potentially hazardous situations that can cause minor or moderate injuries.

CAUTION

Caution without symbol is used for indicating situations that may result in equipment or property damage.

NOTE

Note is used for indicating highlighted information that should be regarded with attention.

General Safety

All persons installing and servicing inverters must be:

•

Trained and experienced in general safety rules for work on electrical equipment

•

Familiar with local requirements, rules and regulations for the installation

NOTE

Before installation

Check for damage to equipment and packaging. If in doubt, contact the supplier before commencing installation.

CAUTION

Installation

For optimum safety, follow the steps described in this document. Keep in mind that the inverter has two voltage carrying sides; the PV input and the AC grid.

WARNING

Disconnecting the inverter

Before starting work on the inverter, switch off AC at the mains switch and PV using the PV load switch. Ensure that the device cannot be unintentionally reconnected. Use a voltage tester to ensure that the unit is disconnected and voltage free. The inverter can still be charged with very high voltage at hazardous levels even when it is disconnected from AC grid and solar modules. Wait at least 8 minutes following disconnection from grid and PV panels before proceeding.

For safe disconnection of DC current, turn off the PV load switch (1).

CAUTION

Maintenance and modification

Only authorised personnel are permitted to modify the inverter. To ensure personal safety, use only original spare parts available from the supplier. If non-original spare parts are used, compliance with CE guidelines in respect of electrical safety, EMC and machine safety is not guaranteed.

The temperature of the cooling racks and components inside the inverter can exceed 70ºC. Observe the danger of burn injury.

DC voltages up to 1000 V are present in a PV system even when the inverter is disconnected from the AC grid. Faults or inappropriate use may lead to electric arcing.

WARNING

Before starting work on the inverter, switch off AC at the mains switch and PV using the PV load switch. Before proceeding wait at least 8 minutes after disconnection from grid and PV panels, until the inverter has completely discharged. Failure to switch off AC and PV and wait for discharge may result in personal injury.

The inverter will only detect the option, when the option is installed in an unpowered state.

CAUTION

Do not penetrate or open the housing of the option.

Opening or penetration may result in equipment damage.

1.1 Installation

To install the option:

1. Take the GSM option. Insert the SIM card into the slot labelled 'SIM Card'. See Illustration 1.2.

Push the card fully into position. Secure it by moving the slider to locked position. See Illustration 1.3.
