Table 2: ECB-PTU Controllers protection

The controller must be connected to the mains using the provided detachable connector.

The Network Guide provides extensive information and requirements for powering a controller that uses a BACnet network for communications. It can be

downloaded from our website.

Use an external circuit breaker/fuse on the mains to protect the module against power line spikes. The circuit breaker must be located close to the con-

troller.

Power wiring

The power wires must remain between 1 mm² (17 AWG) and 1.5 mm² (16 AWG). Make sure the cable performances suit the connected

loads.

Operating, handling, or servicing this product must be achieved by a qualified operator. Turn off power before any kind of servicing.

Input Wiring

Each controller has physical connections for six (6) inputs (marked as UIx for Universal Inputs, DIx for Digital Inputs, and SIx for Sensor Inputs). All in-

puts must be configured properly in EC- gfx Program to ensure proper input readings.

All input wiring must be connected using the provided detachable connectors.

Before connecting a sensor to the controller, refer to the installation guide of the equipment manufacturer.

Connectors allow the use of cables up to 1.5 mm² (16 AWG).
