BoxFan
BF700S-355RT01I2
With square air inlet and outlet
BoxFan is a fan with low energy consumption and low noise emission. It is ideal for moving air in new installations as well
as for replacing existing fans when energy renovating or as spare part.
BoxFan consists of a box of warm-galvanized sheet metal, which are lined with 20 mm. insulation.
This ensures effective insulation against noise and condensation and makes it resistant to various climate impacts
Inside the box, the fan is mounted on a warm-galvanized sheet metal plate and this is accessed by removing the
inspection hatch.
The fan itself is an EC fan with high efficiency. The motor has built-in electronics for stepless control, which can be
controlled via potentiometer, pressure control or other equipment that can be purchased. See connection diagram.
On this motor, backward curved fan wheels are fitted. The wheel/impeller are of the RadiCal type, which is developed
with high efficiency at the lowest possible noise levels in mind.
Thus, no additional parts are required to cause the fan to provide an energy-friendly and quiet function.

37 CAUTION
Voltage
The fan is a built-in component and has no disconnecting switch.
Only connect the fan to circuits that can be switched off with an all-pole disconnection switch.
When working on the fan, secure the system/machine in which the fan is installed so as to prevent it from being
switched back on.
38 NOTE
Electrical noise and consequent malfunction.
Provide a gap between the supply cable and the control cable when installing these in the application.
Provide adequate distance.
Recommendation: distance> 10 cm (separate wiring).
39 NOTE
Water ingress into wires or cables.
Water ingress at the customer end of the cable can damage the device.
Make sure the end of the cable is connected in a dry environment.
40 Only connect the fan to circuits that can be switched off with an all-pole disconnection switch.
4.3 Requirements
41 Check whether the information on the nameplate matches the connection data.
Before connection the device, make sure the power supply matches the device voltage.
Only use cables designed for the current level indicated on the nameplate.
4.4 RCD
If your system requires the use of an FI relay, it is only permitted to use FI relays that are sensitive to all types
of current (type B or B +). Personal protection is not possible with FI relays when operating the unit, as is the
case with frequency inverters. When connecting the unit voltage supply, pulse-shaped charging currents from
the capacitors in the integrated EMC filter can cause the activation of delayed release FI relays. We recommend
fault current switches with a triggering threshold of 300 mA and delayed release (super-resistant, characteristic
K).
