Step 3. Select a location to install.
• Install the AC Master in a well-ventilated room protected against rain, snow, spray, vapour, bilge,
moisture and dust.
• Ambient temperature: -20 to 40°C / -4 to 104°F.
• Never use the AC Master at a location where there is danger of gas or dust explosions. Mount
the AC Master vertically with the cables hanging downwards and so that airflow through the
ventilation openings is guaranteed. Mounting the AC Master in another position is possible but
influences the ingress protection degree (IP)!
• No objects are to be located within a distance of 10 cm / 4 inch around the AC Master.
• Do not install the AC Master in the same compartment as the batteries. Do not mount the AC
Master straight above the batteries because of possible corrosive sulphur fumes.
Step 4. Remove the fuse cover and DC fuse(s).
Step 5. Mount the AC Master with four screws to a solid surface.
Step 6. Connect the chassis ground terminal to the central grounding point of the vehicle/ship.
