3 Product overview
3.1 Function
•Transformer control unit for speed control of voltage-controlled 3 ~ fans.
•In the case of R-DT/RTRD types, steps are manually set via the integrated 5-step switch.
•In the case of RUDT types, steps are manually set via both separate 5-step switches.
Switching between both settings is done via an external contact, e.g. from a time switch:
–Terminals 1-2 bridged Operation with step from switches "A" (left)
–Terminals 2-3 bridged Operation with step from switches "B" (right)
•Integrated operating indicator lamp (goes out in the case of motor fault).
•Remote control (ON/OFF) via potential-free contact (terminals RT - RT). If remote OFF lamp for
power not OFF!
•Switch-off with locking mechanism, e.g. for frost protection thermostat via a potential-free contact (
“FS - FS” terminals). Recommissioning is the same as after a motor fault.

4 Installation
4.1 General notes
Attention!
Mounting, electrical connection, and start-up operation may only be carried out by an electrical
specialist in accordance with electrotechnical regulations (e.g. EN 50110, EN 60204, IEC 364)!
•The 5 electrical safety rules must be observed!
•Cover neighbouring electrical equipment during installation work.
•Before installation remove the device from the packing and check for any possible shipping
damage! Start-up is not allowed in the case of transport damage!
•At a weight greater than 25 kg for men / 10 kg for women, the device should be lifted out by two
persons (according to REFA). The values may differ from country to country.
•Wear safety shoes and gloves for handling!
•Assemble the device on a clean and stable base. Do not distort during assembly! Use the
appropriate mounting devices for proper installation of the unit!
•Do not mount equipment on vibrating base!
•Do not allow drilling chips, screws and other foreign bodies to reach the device interior!
•The device should be installed in a location where it will not be disturbed, but at the same time can
be easily accessed!
•Depending on the housing model use supplied stoppers for cable inlets, cut off necessary cable
inlets respectively to the cable diameter. Or alternative use cable inlet for cable glands. Any cable
ducts openings not used must be sealed!
•The required protective earth connection is established using screws between the housing parts in
metal terminal space covers and housing casings. Commissioning is only permissible after these
screws have been properly attached!

L-BAL-E285-GB 1907 Index 002 Part.-No.
5/12

•Metal screwed-connections are not permitted in plastic housing parts because there is no potential
equalization.
•Care must be taken to avoid direct radiation from the sun!
•The device is designed for vertical installation (bottom cable inlet). A horizontal or reclined installa-
tion is only permissible after technical release of the manufacturer!
•Be sure to observe proper heat dissipation (see Technical data, heat dissipation).
4.2 Minimum space requirement
In order to ensure sufficient ventilation of the device, clearance on all sides of at least 50 mm has to
be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance
applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating exists. This
layout is only then permissible when the air suctioned from the upper unit does not become warmer
than the permissible ambient temperature (see Technical data). I.e., a correspondingly larger clear-
ance or thermal shielding is required.
4.3 Mains connection
Power from the mains is connected to terminals: PE, L1, L2, L3 and N (only for 400 V version). Here, it
must be strictly observed that the mains voltage lies within the allowable tolerance specifications (see
Technical data and nameplate affixed to the side).
The mains voltage must comply with the EN 50160 quality characteristics and the defined standard
voltages in IEC 60038!
Danger due to electric current
•The internal transformer is not short-circuit-proof, note: maximum size of line fuse detailed in the
operating instructions. When using automatic circuit breakers, you must use a 3-poled type with “C”
characteristics.
•To prevent transformer overloading, exclude two-phased conductance by taking measures at the
customer location. Alternative to phase monitoring, a motor overload protector with phase-failure
sensitivity can be used as the backup fuse. Set it to the rated current of the transformer-induced
control device.
4.4 Motor connection
The motor leads are connected to the terminals: PE, U, V, W. Several fans can be connected to the
controller-the maximum total current of all motors must not exceed the current rating for the controller.
Motor protection via connection of TB thermostatic switches (not suitable for PTC thermistors). When
the thermostatic switches are triggered (motor fault), the device switches off. Restart is performed
once the drive has cooled down either by switching the mains voltage off and on again (after approx. 2
minutes) or via the switch.
Attention!
If multiple motors are connected, connect thermostatic switches to the TB-TB (TK-TK) terminals in
series.

4.5 Operation signalling contacts/voltage output
Operating indicator contacts, e.g. for shutter control (for contact load, see connection diagram).
•Potential-free contacts (only available in the case of R-DT.. and RTRD..EK types):
–If the device is switched on when mains voltage is applied (stage 1 - 5), the internal relay is
energised ( > in the case of R-DT.. types, terminals 11 - 14 bridged, in the case of RTRD14EK,
terminals 21 - 24).
–In the case of switch-off via the remote control (RT - RT terminals interrupted) and in the case of
a motor fault (TB-TB / TK-TK terminals interrupted), the relay is de-energised ( > in the case of
R-DT.. types, terminals 11 - 12 bridged, in the case of RTRD14EK, terminals 21 - 22 bridged).
•Voltage output in the case of R-DT.. and RUDT.. types:
–The L↓ and N↓ terminals are directly connected to the mains connection, meaning that there is
continuous voltage when mains voltage is applied, even in the switch position “0”.
–The mains voltage at terminal L' is switched via the internal relay (voltage ON
L' - L↓ terminals
bridged).
•Voltage output in the case of the RTDRD14EK type:
–Terminal 1 (N) is directly connected to the mains connection.
–The mains voltage at terminals 2 and 3 is switched at the same time with the relay for potential-
free contacts.
Examples of the connection of throttle actuator motors in the case of R-DT.. and RUDT.. types
•For motors with 1-wire control (see
| 1K | )
–damper “OPEN”: if fan is running, “230 V” at terminal L'
–damper “CLOSE”: constant voltage at terminal L↓, if fan is not running (also in switch position
“0”)
•For motors with spring return (see
| 2K | )
–damper “OPEN”: if fan is running, “230 V” at terminal L'
–damper“CLOSE:”via spring return (if no voltage at) L'
•For motors with 2-wire control only in the case of R-DT.. types (see
| 3K | )
–damper “OPEN”: if fan is running, voltage at terminal 14
–damper “CLOSE”: voltage at terminal 12, if fan is not running (also in switch position “0”)
