IV Smart EC / Modbus | 7 Installation 7.1 Safety information Warning Danger from falling fan or fan parts. Check the surface before installation for load bearing capacity. ◊ Installation may only be carried out by adequately qualified persons, see Table 1: Qualifications ◊ Wear protective equipment during all work in the vicinity of the fan, see 2.2 Personal protective equipment. ◊ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
| IV Smart EC / Modbus Mounting to concrete: ◊ If using Post-Installed Mechanical Anchors (expansion or undercut), anchors must be tested and evaluated to ACI 355.2 requirements. ◊ If using Post-Installed Mechanical Anchors (Adhesive), anchors must be tested and evaluated to ACI 355.4 requirements.
IV Smart EC / Modbus 8 Electrical connection 8.1 Safety information Warning Danger from electrical voltage. ◊ Observe the 5 rules of electrical safety, see 2.3 Five rules of electrical safety. ◊ Prevent the ingress of water into the connection box. ◊ The electrical connection must be carried out by qualified persons, see Table 1: Qualifications. ◊ Wear protective equipment during all work in the vicinity of the fan, see 2.2 Personal protective equipment.
| IV Smart EC / Modbus 8.4 Motor Controls ◊ Each fan contains two EC motors that have their own wire leads landed in the electrical box of the fan. ◊ Each fan type is speed controlled differently. ◊ The IV Smart EC fan is controlled via an analog PWM or 0-10V signal. ◊ The IV Smart EC Modbus is controlled by digital Modbus communications. Each motor must be individually addressed on the job site.

The left side of the below image is the field wiring side. Line voltage (L1, L2, Ground): • Field power connections are to be made in the electrical box • The grounding terminal is electrically connected to the unit through the DIN rail.
IV Smart EC / Modbus 8.6 | 15 Residual current circuit breaker ◊ All-current-sensitive residual current circuit breakers are required for use in alternating-current systems with 50/60 Hz, in combination with electronic devices such as EC motors, frequency converters or uninterruptible power supplies (UPS). 9 Commissioning 9.1 Safety information ◊ Commissioning may only be carried out by adequately qualified persons, see Table 1: Qualifications.
| IV Smart EC / Modbus ◊ Operation may only be carried out by adequately qualified persons, see Table 1: Qualifications. ◊ The device may only be operated by people who understand the function and risks and can act accordingly. ◊ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor. 10.2 Preconditions ◊ Ensure access only to persons who can safely handle the device.
IV Smart EC / Modbus | 17 11.3 Maintenance As set forth in the Limited Warranty, warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is provided. We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning, replacing defective components or other corrective measures.
| IV Smart EC / Modbus 11.4 Variable speed fans Important Varying speeds may lead to increased vibrations dependent on the support structure. ◊ Pay particular attention to damage from vibrations. ◊ After commissioning, start with shorter maintenance intervals. ◊ If no damage occurs, adjust the maintenance intervals up to those stated in the operating instructions. ◊ Responsibility for gradual adaptation is with the system operator/installer. 11.
