Prior to initial commissioning, the rated motor current must be set on the
overload relay by means of the current dial (￫ table 1, ￫ table 2, page 33).
CAUTION

If the overload relay is installed at a cool location (e.g. -5 °C) and
the motor is installed at a warm motor installation site (e.g.
40 °C), it is possible that there will be a delayed release during
an overload if the devices are operated in the lower current
setting range.
The user can select automatic restart "A" or manual reset "H" on the
ZB-.../XTOB... overload relays by means of the Reset selector button.
