Chapter 2: Pre-Installation Planning
WARNING
It is important to respect the clearances above and below the enclosure to allow
airflow to the heatsink.
Nylon Cable Glands
NOTE: Nylon cable glands are permitted for cable or wire fastening.
WARNING
Use watertight compression cable glands rated IP54 for each cable used.
WARNING
Use silicone to seal the cable gland rated IP54 if more than one cable is use in the
same cable gland.
WARNING
The warranty is void if the product enclosures are not sealed correctly and the
installation does not respect the manufacturer recommendations.
WARNING
Ensure all cables enter through the bottom of the plastic enclosure. Do not make
holes on the top or on the sides of the enclosures. Be careful not to damage the
electronic cards located inside the enclosure when drilling at the bottom of the
enclosure.
NOTICE
The use of flexible tube with water and dust tight connectors at both ends is
acceptable.
Cable Support When not Using Rigid Conduits
Support the cables with clips or cable trays whenever possible to avoid damage at the connection points.
IMPORTANT: Refer to the national code for more details about possible installations.
Cable Routing
NOTICE
Never run low voltage (24V and less) wires like communication wires, inputs or
sensors wires in the same conduit or underground trench as a High Voltage (Power)
wire.
When low voltage cables run parallel to high voltage cables (120/230/380 VAC or 24 VDC), place them at
a distance of at least 460 mm (18 inches) from each other to avoid electromagnetic interference. This
also applies to high and low voltage cables running through an underground trench.
If low voltage cables cross high voltage cables, ensure they cross at an angle of 90° to minimize electro-
magnetic interference.
