Installation
Chapter Objectives The following data will guide you in planning the installation of Bulletin
1395 drives rated at 1–300HP @ 230VAC and 2–600HP @ 460VAC. For
1395 drives rated at or above 700HP @ 460 VAC, or 750HP @
575VAC/660VAC, refer to publication 2361–5.01 for installation
instructions. Since most start-up difficulties are the result of incorrect
wiring, every precaution must be taken to assure that the wiring is done as
instructed.
IMPORTANT: The end user is responsible for completing the
installation, wiring and grounding of the 1395 drive and for complying
with all National and Local Electrical Codes.
WARNING: The following information is merely a guide for
proper installation. The National Electrical Code and any other
governing regional or local code will overrule this information.
The Allen-Bradley Company cannot assume responsibility for
the compliance or the noncompliance to any code, national, local
or otherwise for the proper installation of this drive or associated
equipment. A hazard of personal injury and/or equipment
damage exists if codes are ignored during installation.

Environment The drive must be mounted in a clean, dry, location. Contamination from
oils, corrosive vapors and abrasive debris must be kept out of the
enclosure. Temperatures around the drive must be kept between 0
°
C and
55
°
C (32
°
F and 131
°
F). NOTE: For drives mounted in Bulletin 2100
MCCs, the ambient temperature may not exceed 40
°
C. Humidity must
remain between 5% to 95% non-condensing. The drive can be applied at
elevations of 3300 feet (1,000 meters) without derating. The drive current
rating must be derated by 3% for each additional 1,000 feet (300 meters).
Above 10,000 feet (3,000 meters), consult the local Allen-Bradley Sales
Office.
Mounting The 1395 drive is of the open type construction and is designed to be
installed in a suitable enclosure. The selection of enclosure type is the
responsibility of the user. The heat sink is electrically isolated and is used
as a mounting surface. Refer to the following figures for dimensions.
WARNING: Shock hazard exists at motor armature terminals if
gravity drop out contactor does not open. The drive must be
mounted in the vertical position. Failure to observe this
mounting practice can result in personal injury or death.
