3.2.10.1 Recommendations for RS-232 Wiring

a) Always power-off all the IPS110 supplies before inserting/removing the RS-232 serial

connector.

b) Use a 9-wire standard 1-to-1 (non-inverting) shielded cable, preferable with metallic or

metallized shells (casings)

CAUTION!

DO NOT CONNECT/DISCONNECT THE RS-232 CABLE
WHILE THE DRIVE IS POWERED ON. THIS OPERATION
CAN DAMAGE THE DRIVE
