Installation
CAUTION/ATTENTION:
Height above sea level:
If installing a BT300 Bypass at an altitude
higher than 3,280 feet (1000 m), de-rating is
required.
Élévation au-dessus du niveau de la mer. En
cas d’installation d’un BT300 Bypass à une
altitude supérieure à 1000 m (3280 pieds), un
déclassement doit être prévu.
CAUTION/ATTENTION:
Never run control or drive input wires in
the same conduit as the drive output
wires.
Séparer les câbles d’entrée de
commande ou de variateur des câbles
de sortie de variateur.
Environmental Conditions
Install the BT300 Bypass in a heated, indoor,
controlled environment that is free of moisture and
conductive contaminants, such as condensation
and dust.
The air entering the unit for ventilation/cooling must
be clean and free from corrosive materials.
The ambient temperature must be between 14°F
and 104°F (-10°C and 40°C), and the relative
humidity must be 0 to 95%, non-condensing.
NOTE: Do not mount unit in direct sunlight.
Cable Length
• Place the motor cables sufficiently far from
other cables.
• Avoid placing the motor cables in long parallel
lines with other cables.
• If the motor cables run in parallel with other
cables, see Table 2 for the minimum separation
required between the motor cables and other
cables.
