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
from page 39.
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.
Î Section 3 “Operation and Repairs”
Please note!
The ventilator hood air inlet and outlet must not be obstructed,
as there is the risk of heating beyond the permissible
temperature class and of reducing the life of the winding
insulation
Î Fig. 2 and Î Table 2.
This applies in particular to the use of soundproof covers. The
air ducts must checked and cleaned regularly in factories with
heavy soiling.
