ATB CD Series - Motors with Unidirectional Fan; Motors with Separate Cooling Via Separately Powered; Motors with Temperature Monitoring

25
Motors with unidirectional fan
Make sure that the fan's direction of rotation matches that of the motor.
Motors with separate cooling via separately powered external fans
Make sure by means of the electric control that the main motor can be
operated with the motor switched-on for separate cooling.
Motors with temperature monitoring
Terminals 1TP1-1TP2 or 2TP1-2TP2
The motors are equipped with PTC's as per DIN 44081. Take note of the
temperature data and tripping time
t
A
on the rating plate.
Connect the PTC to an approved tripping device with marking PTB 3.53-
PTC/A or
II(2) G.
Please note!
The tripping device is not explosion-protected. For this reason
install them outside the areas subject to explosion hazards.
The marking confirms whether the electrical data on the interface between
the temperature sensor circuit and the tripping device have been fulfilled. The
use of the tripping device with PTC temperature sensors as per DIN 44081 is
allowed for the thermal monitoring of explosion-protected electrical
machinery.
Being the only overload protection as set forth in EN 60079-14, the
temperature sensors herein described can be used together with an
approved tripping device only if the tripping time
t
A
is specified on the
motor rating plate. (Refer to Section 3, Operation & Repairs, page 42)
