4 1204 Reflected Wave Reduction Device with Common Mode Choke
Determining the Maximum Cable
Length for your System The following tables will help you determine the maximum cable length for
your system.
1336 Plus / Plus II /Impact/1336T 3.7-7.5 kW (5-10 HP) and 3.7-7.5 kW (5-10 HP) Motors
Table A: 380-400V Drives
Table B: 480V Drives
Table C: 600V Drives
(1) Type A = No phase paper or misplaced phase paper, lower quality insulation systems, corona inception voltages between 850 and 1000 volts.
Type B = Properly placed phase paper, medium quality insulation systems, corona inception voltages between 1000 and 1200 volts.
1329 R/L = “Control Matched” motors for use with Allen-Bradley drives, premium grade insulation system, typical corona inception voltage is 1600 volts.
(2) Includes wire run in conduit.
(3) High line condition is defined at rated input system voltage +10% with a fully rated motor condition.
(4) Maximum cable length is restricted by power dissipation within the 1204-RWC package at 40°C (104°F) ambient under rated load.
(5)
When used on 600V systems, 1329 R/L motors have a corona inception voltage rating of approximately 1850V.
(6)
Not recommended with 1204-RWC.
Call factory for advice on using the 1204-RWC with drives other than the 1336 family of AC drive.
