Before installing this option, a TECHNICALLY QUALIFIED INDIVIDUAL, who is familiar with this type of
equipment and hazards involved, should READ this ENTIRE INSTRUCTION SHEET.
DESCRIPTION
The RS-232C/485 Interface Card CM086 (Figure 1) is mounted on the Control Board of the GPD 505 to
input/output various signals from external devices by means of RS-485 serial communication.
RECEIVING
All equipment is tested against defect at the factory. Report any damages or shortages evident when the

INSTALLATION AND WIRING
WARNING
Hazardous voltage can cause severe injury or death. Lock all power sources feeding
Drive in "OFF" position.
1. Disconnect all electrical power to Drive.
2. Remove Drive front cover. Check that “CHARGE” indicator lamp inside Drive is off.
3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals
(L1, L2, L3).
CAUTION
The option card uses CMOS IC chips. If proper electrostatic discharge (ESD)
protective procedure is not used when handling the card, the ICs may be damaged,
resulting in erratic performance of the drive.
4. Refer to Figure 2. Position the option card on four mounting spacers on the Control Board of the Drive.
Gently press the card into place until its four mounting holes click into place on the the spacers.
5. Plug the 2CN cable from the option card into connector 2CN of the Control Board.
