2 Installation and Wiring
2.1 Installation
The MD500-EN1 is installed inside the MD500 series AC drive. Before installation, de-
energize the AC drive and wait about 10 minutes until the charging indicator on the AC
drive becomes o. Then, insert the MD500-EN1 card into the AC drive and fasten the
screws to avoid damage caused by external signal cable tension on the signal socket
between boards. The installation is shown in"Figure 2-1 Installation of the MD500-EN1
card".
Note that the ground terminals of both the MD500-EN1 card and AC drive must be
connected properly, as shown in"Figure 2-2 Ground terminal connection between the
MD500-EN1 card and the AC drive".
