18 | Smart 108/116 IP
2.3 Pre-Installation Guidelines
 Place cables away from fluorescent lights, air conditioners, and machines that are
likely to generate electrical noise.
 Place the Smart 108/116 IP unit on a flat, clean and dry surface.
 The Smart 108/116 IP unit is not intended for connection to exposed outdoor
lines.
 Ensure that the maximum distance between each computer and the Smart
108/116 IP unit, does not exceed 10 m / 33 ft for RICCs, and 30 m/100 ft for
ROCs.
2.4 Rack Mounting the Smart 108/116 IP Unit
2.4.1 Rack Mounting Safety Considerations
When mounting Smart 108/116 IP onto a rack, avoid the following conditions:
 Elevated operating ambient temperature – The operating ambient temperature of
the rack environment may be greater than the room ambient temperature.
Therefore, take special care when installing the unit in a closed or multi-unit rack
assembly that the environment is compatible with the maximum rated ambient
temperature.
 Reduced airflow – Install the equipment in a rack in such a way that the amount of
airflow required for safe operation is not compromised. Leave a gap of at least 5
cm / 2” on each side of Smart 108/116 IP.
 Uneven mechanical loading – Uneven loading can cause damage to the equipment
or personal injury. Mount the equipment in the rack in such a way that a
hazardous condition does not result due to uneven mechanical loading.
 Circuit overloading – When connecting the equipment to the supply circuit, make
sure that the total power of all the components does not exceed the circuit
capabilities. Overloading of circuits can affect over-current protection and supply
wiring, potentially resulting in fire and shock hazards.
 Unreliable earthing – Maintain reliable earthing of rack-mounted equipment. Pay
attention to supply connections other than direct connections to the branch circuit
(for example, use of power strips).
