SAFETY INSTRUCTIONS AND ALARMS!
Prior to installation and use of the unit, please read this Manual carefully. Installation, connection and maintenance shall be executed by a qualified
specialist considering the local rules, normative acts and practice. Prior to connecting peripherals to the board, please read the Manual. The Company
shall not assume any liability for personal injuries or damage to property in case of failure to observe these safety requirements, if the product is
modified without manufacturer’s consent
Electrical power switching and unit maintenance shall be performed only by qualified employee following the manufacturer manual and applicable
safety instructions.
 To reduce a potential risk during maintenance or installation works appropriate safety clothes shall be worn.
 Electrical power to power mains must be connected via appropriate rating circuit-breaker.
 All control gears need to be powered from the main switchgear equipped with appropriate protection of wires powering the control box.
 Assembly, wiring and start-up of the control gear should by done by qualified staff only.
 For applications subject to strong vibrations (1.5 mm pk-pk 10/55 Hz), secure the cables connected to the μPC using clamps placed around
3 cm from the connectors.
 The entire length of the input/output connections must be less than 30 m, according to EN 61000-6-2.
 Installation must be performed according to the standards and legislation in force in the country where the appliance is used.
 In the event of malfunctions do not attempt to repair the controller, but rather contact the service.
Without additional elements the control gears can work inside a building. Assembly outside in a moderate climate is permissible if an additional
heating module is assembled.

Cabling
Connect power leads of the control gear and
frequency converter of the fan drive according to
the Electric diagram.
The wire cross-sections have been selected for long
term current capacity for cables arranged in the air
(supported on brackets, cable racks, in perforated trays) with
spacing from the wall of min. 0.3 cable diameter, insulated with PVC,
for 3-conductors loaded.
Due to the protection selectivity, length, cable placement method
and short-circuit currents, revise the feeders’ cross-sections in the
table below.
