It contains important instructions that need to be followed during installation, operation and maintenance. Save these instructions for future reference on operation and maintenance. Danger of battery explosion from sparking. Danger of electric shock. High DC voltage is supplied to the MPPT when a connected PV array is exposed to light. Ensure that both the DC and PV system is fully shut down and properly isolated prior to disconnection of any existing cabling and prior to making any electrical connections. Install the product in a heatproof environment.
Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the equipment.

The battery manufacturer's safety instructions should always be observed.
Protect the solar modules from incident light during installation, e.g. cover them. Ground the frame of the PV panels to reduce the impact of lightning. Do not connect the solar charger to a grounded PV array. On the MPPT 100/20 model only, a separate ground path for the chassis ground is permitted because the chassis is isolated from the positive and the negative terminals. Never touch uninsulated cable ends. Use only insulated tools. This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only. Using this equipment outside of its specifications may impair its safety protections.
Connections must always be made in the sequence described in the Installation [11] chapter of this manual. The installer of the product must provide a means for cable strain relief to prevent the transmission of stress to the connections. In addition to this manual, the system operation or service manual must include a battery maintenance manual applicable to the type of batteries used. For the 100/15 model only This product shall be installed inside a suitable fire enclosure. The installer is responsible for ensuring that the final system complies with applicable fire protection requirements of IEC 62109-1 and relevant local regulations. Page 1 Safety precautions
