1.1. General safety precautions

MPPT solar charger manual 1. Safety precautions 1.1. General safety precautions Read this manual carefully. 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 product is not allowed to be mounted in a user accessible area. Ensure that the equipment is used under the correct operating conditions. Never operate it in a wet environment. Never use the product at sites where gas or dust explosions could occur. Ensure that there is always sufficient free space around the product for ventilation. Refer to the specifications provided by the manufacturer of the battery to ensure that the battery is suitable for use with this product. 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. 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 [10] 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. Page 1 Safety precautions
