Page 5: Install The Module
Barrel Temperature Control Module Install the Module To install your module into the chassis: 1. Turn off the chassis power supply. If you insert or remove the module while backplane power is on, an WARNING electrical arc can occur. This could cause an explosion in hazardous location installations. - Page 6 Barrel Temperature Control Module 5. To remove, press the releases at the top and bottom of the module, and slide the module out of the chassis slot. card guides top and bottom releases retaining clips Publication 1746-IN020B-EN-P - July 2002...
- Page 7 Barrel Temperature Control Module Remove/Install the Removable Terminal Block The module ships with an attached an 18-position removable terminal block (RTB). When you install the module, it is not necessary to remove the RTB. If you ever need to remove it, follow this procedure: 1.
