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.
IMPORTANT
This option may have been installed by the factory. However, certain steps can
only be completed at the installation site. Therefore, review and then perform
those steps which complete the installation process.
INTRODUCTION
When installed, either of these options allows the user to employ precision analog signals to monitor outputs of
the GPD 515 (U1-01, 02, 03, 05–09, 15–24, 26 & 27), the GPD 503 (output frequency, output current, output
voltage, or DC voltage), or the VCD 703 (Un-03, 04, 05, 21-41, 44).
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.
INSTALLATION
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).
WARNING
HAZARDOUS VOLTAGE CAN CAUSE SEVERE INJURY OR
DEATH. LOCK ALL POWER SOURCES FEEDING DRIVE IN
"OFF" POSITION.
