Electrical Installation

7.1

Safety instructions

These safety instructions warn against dangers that can arise during electrical
installation of the fan.

DANGER

 Risk of injury due to electrical energy

Immediate danger to life due to respiratory and cardiac arrest.

▪ Erroneous or insufficient execution of the electrical connections, the wiring,

and the cable routing as well as the electrical safeguards of the fan.

u

Only authorized, qualified electricians may carry out the electrical installa-
tion and connect the fan to the power supply.

u

The electrical installation is to be executed in accordance with the standard
EN 60204-1, the technical connection requirements, and the relevant regu-
lations.

WARNING

 Trip and fall hazard due to cables run along the floor

Bruises and other injuries.

u

Motor connection cables run along the floor are to be run properly and pro-
tected by a cover.

u

Indicate the trip hazard with floor markings.

WARNING

 Risk of electrical shock due to electrostatic charge

Subsequent injuries due to response upon being startled.

▪ As a precaution, take protective measures against electrostatic charge

when operating the fan.

u

Ground the fan support.

u

For outside mounting, connect the fan support to the lightning protection
system.

CAUTION

 Electrical hazards due to improper layout/undersizing of the

electric motor and protective devices. 
Operation outside of the specified characteristic curves.

u

Size electrical protective devices according to the electric motor and con-
nection cables.

u

Operate only within the specified characteristic curves (flow rate and differ-
ential pressure) according to the technical data sheet.

7.2

Electrical protective devices

7.2.1

Isolation switch installation

Improper use of isolation switch

The isolation switch is only a protective device for disconnecting the fan from
electrical power during mounting, maintenance, or repair work and not to turn
the fan on and off in the context of operation.

The isolation switch

• is a required protective device,

• shall be installed in an easily-accessible location near the fan,
