Installation Guidelines
This chapter describes the guidelines and wiring recommendations to be followed
when installing SD3100 DC Power Modules. Additional information on installing
SD3100 drives can be found in the instruction manuals listed in tables 1.3 and 1.4 on
page 1-4 of this manual.
The installation of the Power Module can be broken down into the following tasks:
• physically installing the unit
• wiring AC power into the Power Module
• wiring DC power out to the motor armature and field
• grounding the drive
• installing feedback devices
Note that System wiring is to be done according to the supplied wiring diagrams
(W/Es), which are application-specific.
3.1 Planning the Installation
Use the following guidelines when planning your Power Module installation:
• Verify that the selected site will provide sufficient ventilation for the Power Module.
The Power Module’s fan pulls in air from the bottom of the chassis and exhausts it
from the top. The ambient temperature must remain between 0 and 40° C (32 to
131° F).
• Be sure surrounding components do not block service access to the Power Module.
• Verify that the relative humidity will be between at 5 and 95% (non-condensing).
• Do not install the Power Module above 1000 meters (3300 ft) without derating. See
figure A.1, Altitude Derating Chart, in Appendix A.
Refer to figure 2.6 (1250A units), figure 2.8 (1650A units), or figure 2.10 (3000A units)
for Power Module dimensions.
