Wall-Mounted Installation; Input Wiring - Distech Controls ECLYPSE ECY-400 Series Installation Manual

Wall-Mounted Installation

1. Use the mounting holes to mark the location of any holes that need to be drilled. You may need to remove terminal block connectors to access some
of the mounting holes.
Figure 9: Mounting hole locations
2. Drill the holes and clean the surface.
3. Mount the module using a No. 8 slotted hex, size: 1/4" (0.6cm) or equivalent mounting hardware appropriate to the wall material type.

Input Wiring

Input options must be properly configured in EC- gfx Program to ensure correct input readings. The table below shows the controller's available universal
input (UIx) wiring methods. For terminal block connector wiring best practices, see General Wiring Recommendations. Inputs can be connected as fol-
lows.
Before connecting a sensor to the controller, refer to the installation guide of the equipment manufacturer.
£
For a wire length less than 75' (23m), either a shielded or unshielded 18AWG wire may be used.
£
For a wire up to 200' (61m) long, a shielded 18AWG wire is recommended.
£
The shield of the wire should be grounded on the controller side only and the shield length should be kept as short as possible.
£
