• Make sure the equipment is correctly connected to the protective earth conductor of the mains voltage
supply of the system installation through the mains lead.
• Power to the equipment must be via a fused spur.
• The power plug must be inserted in a socket outlet provided with a protective earth contact. The
electrical supply at the socket outlet must provide appropriate over-current protection.
• Both the mains supply and the quality of earthing must be adequate for the equipment.
• Before connecting up the equipment, check that the mains power supply voltage rating corresponds
with the local mains power supply and that the mains fuse is of the correct type and rating.

Location

• Ideally a cool area is preferred not in close proximity to power distribution equipment or other
potential sources of interference.
• Do not install the equipment in places of poor ventilation.
