Page 12 CH2 Series 4.2 Installation Method and Position 4.2.2 Mounting Method 4.2.1 Installation Position and Clearance This device is cooled by natural convention and suggested an indoor installation or an installation under a sheltered place to prevent the product from exposure to direct sunlight, rain and snow erosion.
Page 13 CH2 Series 4.3.2 Mounting Procedures • Keep the device from water sources such as taps, sewer pipes and sprinklers to prevent water seepage. • The product is to be installed in a high traffic area where the fault is likely to be seen.
Page 14 CH2 Series 3. Secure the Screws and the Rear Panel The panels should be secured onto the mounting position by screws as shown in Figure 4.6. Figure 4.6 Secure the panel 4. Mount the Inverter Carefully mount the inverter into the rear panel as shown in Figure 4.7. Make sure that the rear part of the equipment is closely mounted into the rear panel.
Page 15 CH2 Series 5.1 Additional Grounding Cable Electrical connection must only be operated by professional technicians. Before connection, necessary protective equipment must be employed by technicians, including insulating gloves, insulating shoes and safety helmet. WARNING · Connect this additional grounding cable before other electrical connection.
