4. Communication

Physically install the GOLD air handling unit, MIRUVENT 
power roof ventilator and the MIRU Control equipment. 
See separate installation instructions.

4.1. MIRU Control and MIRUVENT power 
roof ventilator

Wiring the connections to MIRU Control

Connect the 3-wire cable to terminals 11 (A), 12 (B) and 
13 (GND) on the control circuit card inside the MIRU Con-
trol unit. See illustration. 

A twisted-pair cable is recommended. 

Wiring the connections to the MIRUVENT

MIRUVENT with AC motor and integrated frequency 
inverter

Unfasten and bend up the upper section of the frequency 
inverter. 

Place the upper section in the groove designed to receive 
it in the lower section. 

Connect the communication cable to terminals A, B and 
GND, next to the Bus marking. See illustration.  

MIRUVENT with EC motor and control system

Connect the communication cable to the wiring terminals 
inside the safety switch enclosure. 

Connect conductor A to terminal 4, conductor B to termi-
nal 5 and GND to terminal 6.

The internal electrical connections to the motor control 
system have already been wired.
