supply prior to every installation or repair

operation.

Ground the control unit!

The unit must not be operated outside the

temperature range stated in the user's manual

or in aggressive or explosive environments.

Do not usedamaged equipment orconductors

to connect the unit to power mains.

Do not change the power cord length at your

own discretion. Do not bend the power cord.

Avoid damaging the power cord.

Do not position any heating devices or other

equipment in close proximity to the unit

power cord.

Do not touch the unit speed controller or the

control panel with wet hands. Do not carry out

the unit maintenance with wet hands. OFF

The unit must be disconnected from the power

supply prior to maintenance operations.

In case of unusual sounds, smoke disconnect

the unit from power supply and contact the

service centre.

SAFETY REQUIREMENTS

www.blaubergventilatoren.de

Freemax / AC208A2

The units are designed for connection to AC 230 V/50 Hz single- or 400 V / 50 Hz three-phase power mains depending on the unit type. The

cable cross section must be in compliance with the unit power consumption, wire type, maximum heating temperature, insulation type, cable

length and installation type.

Use cables with copper wires only!

The unit is connected to power supply on the terminal block according to the wiring diagram and terminal marking. Connect the control and

power cables in compliance with the terminal marking and polarity.

Connection to power mains must be performed via an automatic circuit breaker with magnetic trip, integrated into xed house cabling with

the tripping current exceeding the unit current consumption.
