FRAME 9, 10 AND LARGER (19XR PRODUCT)

The 19XR units with Frame 9, 10, and larger contain:
• PE-A - MOV on the AC precharge control circuit board
• PE-A1 - MOV on the TVSS module
• PE-A2 - Common mode capacitors on the AC common
mode filter circuit board
• PE-B1 - Common mode capacitors on the line side and
motor side power interface circuit boards.
For solidly grounded equipment PE-A, PE-A1, PE-A2 are all con-
nected (in) and PE-B1 is disconnected (out). This is the default
setting for the drive. For high resistance ground system all jumpers
are disconnected (out). High resistance ground systems applica-
tions are non-standard and should be reviewed with Service Engi-
neering/Technical Service Manager and may affect warranty. See
Fig. 18-21.
