AFE in IP21 Rittal Enclosure – Installation/Wiring
Fuses and Circuit Breakers
The IP21 Rittal enclosure for the AFE includes a motor-controlled circuit
breaker (MCCB) and DC bus output fusing. The MCCB is used for precharge
operation. For details on MCCB and precharge operation, see
. For
fuse and circuit breaker information, see
. Local/national electrical
codes can determine additional requirements for the installations.
Power Wiring
Most start-up difficulties are the result of incorrect wiring. Verify that the
wiring is done as instructed. Read and understand the instructions before you
begin to installation the AFE.
Power Cable Types Acceptable for 400…690 Volt Installations
Various cable types are acceptable for PowerFlex Active Front End installations.
For many installations, unshielded cable is adequate, provided it can be
separated from sensitive circuits. As an approximate guide, use a spacing of 0.3
meters (1 ft) for every 10 meters (32.8 ft) of length. In all cases, avoid long
parallel runs. Do not use cable with an insulation thickness less than or equal to
15 mils (0.4mm/0.015 in.). Use only copper wire. Wire gauge requirements
and recommendations are based on 75 °C (167 °F). Do not reduce wire gauge
when using higher temperature wire.
Unshielded Cable
THHN, THWN, or similar wire is acceptable for PowerFlex Active Front End
installation in dry environments provided adequate free air space and/or
conduit fill rates limits are provided.
Do not use THHN or similarly coated
wire in wet areas
. Any wire that is chosen must have a minimum insulation
thickness of 15 mils and cannot have large variations in insulation
concentricity.
ATTENTION:
The following information is a guide for proper installation.
Rockwell Automation does not assume responsibility for the compliance or
noncompliance to any code, national, local, or otherwise, for the proper
installation of this unit or associated equipment. A risk of personal injury and/
or equipment damage exists if codes are ignored during installation.
ATTENTION:
National Codes and standards (NEC, VDE, CSA, BSI, and so forth)
and local codes outline provisions for safely installing electrical equipment.
Installation must comply with specifications regarding wire types, conductor
sizes, branch circuit protection, and disconnect devices. Failure to do so can
result in personal injury and/or equipment damage.
