Terminal Information - Power (Frames 1-5)
Note: On Frame 1 and 2 units, L1, L2, L3, A+ and A- terminals are located on a separate Terminal Board. On Frame 3, 4 & 5 units, they are
busbar connections.

Main contactor

Con L
Line
This terminal is the switched output from the contactor control relay and is derived from
the auxiliary supply at terminal D8. The output is internally fused at 3A hence contactor
coils having a high pick-up current must be operated via a slave relay.
Note: The contacts of the Contactor Control Relay are suppressed by a series connected
resistor (680 Ohms) and capacitor (22nF) to protect the relay contacts. Users should be
aware that when the contactor Control Relay is “De-energised”, a leakage current of
approximately 2mA can be expected and this should be considered when interfacing to
these terminals. Typically, there could be the energisation of very sensitive relays.

It is good practice to protect DC motors against sustained thermal overloads by fitting
temperature sensitive resistors or switches in the field and interpole windings of the
machine.
The drive complies with the requirements of IEC 34-11-2-2 and is suitable for use with
Mark A detectors.
These devices have a low resistance (typically 200Ω) up to a reference temperature
125
o
C). Above this temperature, their resistance rises rapidly to greater than 4kΩ. The
preferred installation is for three detectors to be connected in series between terminals Th1
and Th2.
The 590+ will indicate a motor overtemperature alarm if the external resistance between
Th1 and Th2 exceeds 3kΩ. The alarm can be reset when the resistance falls below 750Ω.
Terminals Th1 and Th2 must be jumpered if overtemperature sensors are not used.
