When using EMS2-ROSF devices with a rated operational current I
(AC51) conjunction with the adapter EMS2-XTH, note that the permissible
thermal continuous current depends on the type of mounting and the ambi-
ent temperature. See diagram below.
Moreover, the maximum permissible current must not be exceeded, even in
startup.

It is not permitted to use the motor starters described in this
Section in potentially explosive areas (ATEX).

The maximum current during start-up of the motor is derived by multiplying
the motor rated current with the "startup factor", which with standard asyn-
chronous motors is usually between 6 and 10.
Contact the motor manufacturer to establish the actual value.
