Physical Installation
Location of the RVS-DX is important to achieve proper performance and normal operating life. The
unit should be installed in an area where it will be protected from:
• Direct sunlight, rain or moisture
• Corrosive gases or liquids
• Vibration, airborne dust or metallic particles
When preparing to mount the RVS-DX, lift it by its base, never by the front cover. For effective
cooling as well as proper maintenance, the RVS-DX must be installed on a flat, non-flammable
vertical surface (wall or panel) using four mounting screws. There must be a minimum of 4.7 inches
of clearance above and below the RVS-DX for sufficient airflow. A minimum of 1.2 inches of
clearance is required on each side of the RVS-DX.
The protected chassis is rated to operate over a temperature range of -14°F (-10°C) to +122°F
(40°C). Relative non-condensing humidity should not exceed 93%.
Enclosures
If the RVS-DX is to be mounted in a customer supplied enclosure, the heat dissipation should be
considered when sizing an enclosure. Maximum surrounding air temperature should not exceed
40°C. Since the RVS-DX does have built in bypass after acceleration, the watts loss is minimized.
The RVS-DX watts loss is approximately 0.4 x the FLA in watts. (example: for a motor of 100A,
expect watts loss of the starter to be 40 watts.) Internal enclosure heating can be reduced by using
additional ventilation.
