Installation
Chapter Objectives The following data will guide you in planning the installation of the
Bulletin 1395. 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.
ATTENTION: 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). 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 high horsepower 1395 drive is delivered in a three bay NEMA 1
cabinet. Mounting holes, cable entries and conduit areas are detailed in
Figure 4.1. Refer to Figure 4.1 for cabinet dimensions.
ATTENTION: 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.
ATTENTION: The installation of the drive must be planned
such that all cutting, drilling, tapping and welding can be
accomplished with the drive removed from the enclosure. The
drive is of the open type construction and any metal debris must
be kept from falling into the drive. Metal debris or other foreign
matter may become lodged in the drive circuitry resulting in
component damage.
