RS-232C/485 Interface Card
Model No. CM085
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 CM085 (Figure 1) is mounted on the Control Board of the GPD 515 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
equipment is received to the commercial carrier who transported the equipment.
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. Plug the 2CN connector on the back of the option card into the 2CN connector (60 pins)
on the Control Board of the Drive. Gently press the card into place until its two mounting holes click into place on
the two spacers at the right side of the Control Board.
NOTE: If this option is being installed on a GPD 515 with speed fedback, the speed feedback card needs to
be temporarily un-installed to allow access to the connector 2CN on the Drive’s Control Board and TC1 & TC2
on the CM085 option card.
