2 Installation
Mechanical checks
After removing the shipping braces and shaft blocks (see also the marking on the motor), the motor shaft must be
rotated by hand. In the case of brakemotors the brake must be vented at standstill (maximum of 10 min). This must
be performed after applying voltage as per the circuit diagram at page 15.
Please note!
Save the shipping braces and shaft blocks for subsequent transportation, as the bearings
risk being damaged during transportation.
Site
The completely closed motors are intended for operating sites in which they are exposed to soiling, humidity and
other open air conditions as per the relevant degree of protection.
The motors must be installed in a place with ambient temperatures of –20 °C to a maximum of +40 °C and a max. of
1000m above sea level. Any permissible ambient temperatures (T
a
) and heights (MSL) other than those indicated
above must be specified on the rating plate. Lower temperatures and values not found on the rating plate require the
use of space heaters
Please note!
The ventilator hood air inlet and outlet must not be obstructed, as there is the risk of heat-
ing beyond the permissible temperature class and of reducing the life of the winding insu-
lation.
This applies in particular to the use of soundproof covers. The air ducts must checked
and cleaned regularly in factories with heavy soiling.
