7. Before deciding on an installation site consider the following guidelines e Verify that NEMA 1 drives can be kept clean cool and dry e The area chosen should allow the space required for proper air flow as defined on page 3 3 Be sure that NEMA 1 drives are away from oil coolants or other airborne contaminants e Do not install the drive more than 3300 feet above sea level without derating output power For every 300 feet above 3300 feet derate the output current 1 Verify that the drive location will meet the environmental conditions in Appendix A Be sure there is adequate clearance for air circulation around the drive For best air movement do not mount VTAC 9 drives directly above each other Note that no devices are to be mounted behind the drive This area must be kept clear of all control and power wiring See Figure 3 4 for recommended air flow clearances 3 4 Mounting the Drive Figure 3 4 Minimum Mounting Clearances 6 if mounted below another VTAC 9 drive VTAC 9 drive or other device Ga 2 0 4 0 0 75 Determining the Total Area Overall dimensions and weights are illustrated in Figure 3 5 to
