4 Topics Installation of the base system 1. Ä Chapter 4.1 ‘Safety instructions’ on page 23 2. Ä Chapter 4.2 ‘Installing the device’ on page 26 3. Ä Chapter 4.3 ‘Establishing the electrical connections’ on page 27 4. Ä Chapter 4.4 ‘Supplying the controller with voltage’ on page 31 4.1 Safety instructions DANGER! Risk of death by electrocution! Observe the following safety instructions when performing the measures described in section Ä ‘Installation of the base system’ on page 23.
Always take the following measures before working on the controller: 1. Switch off all loads. 2. Switch off the DC load circuit breaker (solar module) and secure it against being switched on again or safely cover the solar module (ensure that wind cannot blow off the covering!). 3. Switch off the external battery fuse: Remove the fuse insert from the fuse holder (safety fuse) or switch off the DC line circuit breaker and secure it against being switched on again. 4.
CAUTION! Danger of bodily injury. The device weighs over 6 kg. If in doubt, install the device with two persons. CAUTION! Danger of destroying the device through overloading – Conform to the technical specifications, especially the connection values. See type plate and section Ä ‘Technical data’ on page 124. – When selecting the solar module, note that the open-circuit module voltage is higher than the value specified on the type plate at temperatures below 25 °C.
4.2 Installing the device CAUTION! Danger of damage to the inverter and reduction of power. Observe the following safety requirements during installation: – – – – – – – The mounting location and immediate environment are permanently fixed, vertical, flat, non-inflammable and not subject to constant vibration. A free space of at least 60 mm must be present on all sides of the controller (③ in Fig. 5). The controller must be easily accessible and the display easily readable.
4. 60 mm Use the screws/dowels supplied to fasten the controller to the mounting surface. ི 60 mm 60 mm ི ི ཱ 60 mm ཱ ི Fig. 5: Fastening openings ① /② and free space ③ 4.3 Establishing the electrical connections CAUTION! Always make connections in the following sequence: 1. First connect the load and then the source. Example: First connect the cable to the controller and then to the battery. 2. First connect the positive pole then connect the negative pole.
NOTICE! Use the cable pass-through holes plugged with rubber stops on the bottom of the casing as follows: – 2 large cable pass-through holes for the battery cables; 5 medium-sized cable pass-through holes for the module and "PE" cables; 3 small cable pass-through holes for the sensor cables (1 as a reserve). Feed each cable through the corresponding cable pass-through hole lying opposite to the cable connection, see Fig. 2.
4.3.3 Connecting the battery voltage sensor NOTICE! The external battery voltage sensor cable allows the controller to directly measure the voltage at the battery. This voltage value can be used for compensation of voltage drops across the battery cables. This means that the voltage measurement is not affected by (e.g.) powerdependent voltage drops across the battery cables. ✔ A 2-pin plug with screw terminals for connecting the sensor cable is supplied with the device.
CAUTION! Danger of damaging the devices (e.g. computer) connected to the StecaLink master bus, StecaLink slave bus or the UART interface. The galvanic isolation normally present at the AUX IO, StecaLink master/slave bus and UART connections is disabled if the connected peripheral devices are connected to the "PE" connection of the controller via a common ground/ equipotential bonding cable.
4.4 Supplying the controller with voltage ✔ At least the battery and the solar module have been connected as described previously. 1. Fit the terminal cover so that the danger notice is legible (and not upside-down). 2. Fit the fastening screws. 3. Switch on the external battery fuse: Insert the fuse insert into the fuse holder (safety fuse) or switch on the DC line circuit breaker.
Fig. 7: Display after switching on the external battery fuse NOTICE! The battery can be charged from multiple sources. The following applies: – – – – 32 The battery can be charged by multiple controllers connected to the battery in parallel. The MPPT 6000-M can assume control of other MPPT 6000-S devices. In this type of master/ slave system, a single MPPT 6000-M can control up to 22 MPPT 6000-S devices.
5 Initial commissioning of the base system CAUTION! Danger of damage to the device and reduction of power. Only technical professionals may perform the work described in this section. NOTICE! A basic system consists of only a single MPPT 6000-M or a single MPPT 6000-S. The description of the initial commissioning process only covers the absolute minimum settings necessary. Please consult the relevant sections below for information on further configuration possibilities.
Set the language 1. Press SET. The main menu appears and the Device On/Off entry is selected (Fig. left). NOTICE English is set as the default menu language at the factory.
