Carrier 19XR - Power Jumper Configuration (Head Line); Frame 7 (19 Mv Product)

14
Power Jumper Configuration (Head Line)
PowerFlex 755TL product contains protective MOVs (metal ox-
ide varistors), common mode capacitors, and discharge resistors.
To protect against drive damage and/or operational problems these
devices must be configured correctly.
FRAME 7 (19MV PRODUCT)
The 19MV units with Frame 7 contain:
• PE-A - MOV on the AC precharge control circuit board
• PE-A1 - MOV on the TVSS (Transient Voltage Surge Sup-
pressor) module
• PE-A2 - Common mode capacitors on the AC common
mode filter circuit board
• DR - DC bus conditioner capacitor discharge resistor
See Fig. 14-17. For solidly grounded equipment these are all con-
nected (jumper IN). For any other ground system consult Service
Engineering. Default power jumper settings are all connected
(jumper IN); jumper OUT is marked with a red X in the figures.
