4.4. MIRU Control and
GOLD air handling unit
This section is only of interest if you are wiring electrical
connections to the GOLD air handling unit.
The TBLZ-1-64 connection kit accessory is required. The
connection kit contains a cable adapter and a modular
cable.
Install the cable adapter on the DIN rail inside the electrical
cubicle of the GOLD unit or on another appropriate loca-
tion near this cubicle.
Connect the modular cable between one of the modular
connections on the cable adapter and one of the modular
connections marked ”Internal EIA-485” on the control
unit inside the GOLD unit. See illustration.
Connect the 3-wire cable between MIRU Control and the
GOLD air handling unit.
A twisted-pair cable is recommended.
Connect the cable to terminals 8 (A), 9 (B) and 10 (GND)
on the control circuit card inside the MIRU Control unit.
Connect conductor A to terminal 4 on the cable adapter,
conductor B to terminal 3 and GND to terminal 1. See
illustration.
If more than one MIRU Control unit are to be wired to
one GOLD unit, see Section 4.1 MIRU Control to GOLD in
separate MIRU Control installation instructions.
