When deciding where to install the switch, ensure that:
• The switch is accessible and cables can be connected easily.
• Water or moisture cannot enter the case of the unit.
• Air-flow around the unit and through the vents in the side of the case is not
restricted. You should provide a minimum of 25mm (1-inch) clearance.
• No objects are placed on top of the unit.
• Units are not stacked more than four high if the switch is free-standing.
