1. Only use insulated tools suitable for the voltages this meter is used for Do not connect while the circuit is connected to a power or current source Only place the meter in a dry environment Do not mount the meter in an explosive area or exposed to dust mildew and or insects Make sure the used wires are suitable for the maximum current of this meter Make sure the AC wires are connected correctly before activating the current voltage to the meter e Do not touch the meter s connection clamps directly with your bare hands with metal blank wire or other conducting material as you will risk an electric shock that could cause possible injury serious injury or death Make sure the protection covers are replaced after installation e Maintenance and repair of the meter should only be carried out by qualified personnel Never break any seals if present on this meter to open the front cover as this might influence the functionality or accuracy of the meter and will void all warranty e Do not drop or allow physical impact to the meter as there are high precision components inside that may break and affect the meter measurement negatively e All clamps should be properly tightened e Make sure the wires fit properly in the connection clamps e If the wires are too thin it will cause a bad contact which can spark causing damage to the meter and its surroundings DmmMeteringR 2011 3 PRO1250D CT MODBUS MID User manual 0153 Ex2.
