2 INTRODUCTION

The EC-FAN GATEWAY is a user configurable BACnet protocol communications gateway that provides a bridging platform
for information flow between BACnet and MODBUS protocols.
This smart device is a simple to use controller that can be applied to managing HVAC applications, but above all a special
accessory for the connectivity of all MODBUS protocol ebm-papst fans to the most commonly used building management
system, BACnet.
The program and its parameters are saved to FLASH memory and EEPROM. This results in the EC-FAN GATEWAY retaining
programmable data irrespective of any power failures and thus eliminates the requirement of a back up battery. The
program can be loaded via PC.

2.1 Installation

Mechanical Fastening

The EC-FAN GATEWAY is installed on a DIN rail. To fasten the unit to the DIN rail, press it lightly against the rail. The rear
tabs will click into place, locking the unit to the rail. Removing the rail is just as simple, using a screwdriver through the release
slot to lever and lift the tabs. The tabs are kept in the locked positions by the springs. Note that DIN rail is not provided in
the scope of delivery.

2.2 Power Supply

2.2.1 AC

The power supply is connected between G and G0 (Cf. Figure 1a). For AC installation, it is recommended to use a 30 VA class
2 safety transformer that provides an output voltage of 24 Vac. This is to supply a single EC-FAN GATEWAY only. When
supplying multiple EC-FAN GATEWAY controllers with the same transformer, the transformer’s rated power must be n x 30VA,
where “n” represents the number of EC-FAN GATEWAY controllers being supplied by this transformer.

2.2.2 DC

The power supply is connected between G and G0 (Cf. Figure 1b). The voltage supply required is 48 VDC (36V min to 72V
max).

2.2.3 Fuse

The power supply to the EC-FAN GATEWAY and terminal (or series of EC-FAN GATEWAYs and terminals) should be
separate from the power supply to the other electrical devices (contactors and other electromechanical components) inside the
electrical panel. A 250 V 800 mAT fuse must be installed in the power supply line. The power supply is functionally insulated
from the rest of the I/O circuit, including the serial connections.

2.3 Installation warnings

2.3.1 Operating Environment

Avoid assembling the EC-FAN GATEWAY controller in environments with the following characteristics:

• Relative humidity greater than 90%

• Strong vibrations or knocks

• Exposure to continuous water sprays

• Exposure to corrosive or pollutant gases (e.g. sulphur or ammonia fumes, saline mist, smoke). This is to avoid

corrosion

• and oxidation of the controller unit

• Strong magnetic and/or radio interference. Avoid installation of the EC-FAN GATEWAY close to transmitting

antennas

• Large and rapid ambient temperature fluctuations

• Environments where explosive mixes of flammable gases are present

• Exposure to dust

2.3.2 Connecting the EC-FAN GATEWAY

• Using an inappropriate power supply from the one specified could seriously damage the EC-FAN G ATEWAY.

• Use cable ends that are suitable for the terminals. Loosen each screw and insert the cable ends, then tighten the

screws once completed, lightly tug at the cables to ensure that they are appropriately fitted.

• Avoid touching or coming into close contact with the electronic components fittet on the boards. This is

recommended to avoid electrostatic discharges from the operator to the components. Electrostatic discharges can
have an extremely detrimental effect on the functionality of the EC-FAN GATEWAY.

• Disconnect the controller from the power supply before performing any maintenance or assembly

connections/operations.

• If and when the EC-FAN GATEWAY is not used in the manner specified by the manufacturer, the rated protection of

the device may be compromised.
