3–2 1302 Preinstallation
Publication 1302-5.0 — January, 1998
It is important to properly plan before installing a 1302 Drive to
ensure that the Drive’s environment and operating conditions are
satisfactory. Note that no devices are to be mounted behind the
Drive. This area must be kept clear of all control and power wiring.
Read the following recommendations before continuing with the
Drive installation.
Before deciding on an installation site, consider the following
guidelines:
•
The area chosen should allow the space required for proper airflow
as specified in the next section.
•
Do not install the Drive above 1000 meters (3300 feet) without
derating output power. For every 91.4 meters (300 feet) above
1000 meters (3300 feet), derate the output current by 1%.
•
Verify that the Drive location will meet the following
environmental conditions:
Operating temperature (ambient): 0 to +40
°
C (32 to 104
°
F)
Storage temperature (ambient): – 40 to +65
°
C (–40 to +149
°
F)
Humidity: 5 to 95% (non-condensing)
•
Verify that NEMA 1 Drives can be kept clean, cool, and dry.
•
Be sure NEMA 1 Drives are located away from oil, coolants, or
other airborne contaminants.
•
Verify that the AC power distribution system meets the service
conditions specified in table
Determining Total Area Requirements
Figures 3.1 and 3.2 provide drive dimensions for enclosures B and C
as an aid in calculating the total area required by the 1302 Drives.
Appendix A lists drive weights.
