1. INSTALLATION
1.1 PANEL ASSEMBLY
The controller should be installed in a panel cut out as specified in item 2.1. First remove the mounting clamp and insert the
controller into the panel cut out. Place the unit into the panel cut-out and slide the mounting clamp from the rear to a firm
grip at the panel.
The internal circuitry can be fully removed from the housing without disconnecting any wiring. By using the thumb just
press the tab in the lower part of the front panel, grab firmly the front panel and pull out the circuitry from the housing.
1.2 ELECTRICAL CONNECTIONS
Figure 1 shows the electrical terminals of the controller.
