Caution
• It is essential that the alarm contacts of each computer are connected to a separate alarm system
circuitry.
When mounting the computer, the following has to be observed:
• Never mount the computer near water pipes, drainage pipes, etc.
• Never mount the computer in a place where the weather has direct influence (not in the sun, not in
places where the temperature can rise sharply, etc.)
• Never mount the computer in a humid and/or dusty room and certainly not in the house itself.
Caution
No condensation may take place in or on the computer.
• Use the holes behind the cover screws on the corners of the box to securely fasten the computer.
• Mount the computer on a flat surface with the display at eye level (or a little higher). Ensure that the
gland nuts are at the bottom of the computer.
• Use gland nuts for the connection of the computer. Use the sealing plates to seal gland nuts which
are not used. Seal all gland nuts after connection to prevent the entry of dust, aggressive gases
and/or humidity.
• Ensure that the frequency and voltage of the network for which for this computer is made are the
same as the voltage and frequency present.
• To protect against lightning, place an over voltage protection device in the power supply of the
computer. Provide an ample ground wire.
• Connect each computer to its own circuit breaker from the main electrical service panel.
• It should be possible to disconnect the computer using a switch or plug.
Caution
Ensure the computer is well grounded.
• Separate high and low voltage wires by mounting them in separate cable channels.
• If metal cable channels are used, then ground them.
• Use the correct wires as shown on the connection diagrams.
Advice
• Limit the length of the signal wires as much as possible.
• Avoid crossing high/low voltage wires.
