3500 Flat Panel Industrial PCs

Installing the System into a Panel
The system’s rugged design allows it to be installed in most industrial environments.
The system is generally placed in a NEMA 4/4X/12 enclosure to protect against
contaminants such as dust, moisture, etc. Metal enclosures also help minimize the
effects of electromagnetic radiation that nearby equipment can generate.
Mounting Considerations
Once you have established a location for the 3500, install it in the enclosure
according to the instructions that follow:
•
Select a NEMA rated enclosure and place the unit to allow easy access to the system
ports.
•
Account for the unit’s depth when choosing the depth of the enclosure.
•
Provide a NEMA 4 seal by mounting the unit in an approved enclosure that has a 14
gauge (0.075"/1.9mm thick) steel or (0.125"/3.2mm thick) aluminum front face.
•
Mount the unit in an upright position.
•
Place the unit at a comfortable working level.
•
Consider locations of accessories such as AC power outlets and lighting (interior
lighting and windows) for installation and maintenance convenience.
•
Prevent condensation by installing a thermostat-controlled heater or air conditioner.
•
To allow for maximum cooling, avoid obstructing the airflow.
•
Place any fans or blowers close to the heat generating devices. If using a fan, make
sure that outside air is not brought inside the enclosure unless a fabric or other
reliable filter is used. This filtration prevents conductive particles or other harmful
contaminants from entering the enclosure.
•
Do not select a location near equipment that generates excessive electromagnetic
interference (EMI) or radio frequency interface (RFI) (equipment such as high power
welding machines, induction heating equipment and large motor starters).
•
Place incoming power line devices (such as isolation or constant voltage
transformers, local power disconnects, and surge suppressers) away from the system.
The proper location of incoming line devices keep power wire runs as short as
possible and minimizes electrical noise transmitted to the unit.
•
Make sure the location does not exceed the unit’s shock, vibration, and temperature
specifications.
•
Install in the rack or panel in such a way as to ensure that it does not cause a hazard
from uneven mechanical loading.
•
Incorporate a readily accessible disconnect device in the fixed wiring on permanently
connected equipment.
•
Avoid circuit overloading of the supply circuit.
