2.Installation Manual

1.Caution during operating

Please pay attention to the following points when installing the machine.

(1)If the equipment is hoisted, lowered or transported, it must be supported at both sides by a minimum of two people so there is no danger of it falling.

(2)If a forklift, etc. is used to transport the equipment, make sure there is nothing that could impede the forklift on its route to the final destination.

(3)When installing the equipment, be sure the site meets the following criteria:

1)There must be no dripping water in the area.

2)The environment must be free of harmful elements, such as humid or acidic air, air with a saline or sulfur content, where there is poor ventilation, or where air pressure or temperature is abnormal.

3)The equipment must not be placed at an angle or subjected to vibration or shock (this includes during transportation).

4)The equipment must not be kept where chemical products are stored or where gasses are generated

5)The site’s power supply must be of the correct voltage and frequency for the equipment.

6)The site must be connected to a fully earthed cable with sufficient ground resistance to meet standard values.

(4)After installation, be sure to dispose of waste product packaging with care and with full respect for the environment.

(5)As the imaging unit is easily portable, take special care that it is not knocked, dropped or subjected to strong shocks.

(6)Use clamps to secure any excess cable for the imaging unit.
