4.1  Electrical Installation  

 

 

 

 WARNING 

 

Protective Earth on Ex-Model 

Bearingless  Fans  placed  in  Ex  classified  locations  must  be  connected  to 
protective earth, which must be done with the earth wire according to Table 5.
 

4.1.1  Installation Instructions for Power Supply 

 

 

 

 

WARNING

 

Hazardous voltage may be present. 

Always  isolate  the  electrical  power  supply  before  making  or  changing 
connections to the unit. 

In case of usage of an inadequate AC/DC power supply, mains voltages 
may be present (even if the system is designed for 48 VDC). The usage 
of a galvanically separated power supply, which is certified by a 3

rd

 party 

(UL or CE), is required. 

 

 

Power requirement:

 See section 3.1 for the power consumption of the bearingless fan. Depending 

on  the  operating  point,  one  power  supply  may  be  used  to  power  several  bearingless  fans 
simultaneously, or a supply with a lower power rating may be used. If other power supplies are used 
than the ones tested by 

Levitronix

®

, it is highly recommended to test these under dynamic conditions 

(acceleration and deceleration of the fan up to maximum rotational speed). 

 

Connection:

  Make  sure  the  AD/DC  power  supply  is  off  before  connecting  the  fan  (see  also

 

section

 

3.1.2

). Connector type 

TE D3200 1-178128-3

 is used as the power connector of the fan. Use 

TE D3200 1-179553-3

 to connect the power supply (cable adapter available as accessory). Make sure 

pin allocation is according to 

Table 5

 and connect the cable shield to earth.

4.1.2  Installation of PLC Interface Signals 

To operate the bearingless fan with a PLC, a minimum set of one digital input and one analog input is needed 
for speed control, or a set of two digital inputs and two analog inputs for process (pressure or flow) control. 
The digital and analog outputs can be used to monitor system status and operating parameters (see 

Table 6

). 

 

 

CAUTION 

 

The  analog  inputs  and  analog  and  digital  outputs  are  not 
galvanically isolated from the motor electronics.

 

 

 

Connection: 

Connector type 

TE D1200 1-1827864-6

 is used as the PLC connector of the fan. Use 

TE D1200 1-1903131-6

 to connect the tool control (cable adapter available as accessory). Connect 

the desired interfaces to the respective pins according to 

Table 6

. 

Figure 14

 provides a reference for 

hardware configuration of the PLC inputs and outputs.
