Technical Specifications E-19
DC590+ Series DC Digital Drive
Terminal Information - Power Board (Frames 1-5)
Note that 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.
Frame 3 units have terminal designations D1 to D8, shown in brackets in the Terminal Number column of this table.

Line
These terminals are the mains input connections for the switch mode power
supply and contactor control relay supply. Refer to the Product Code (Block 8)
for the specified auxiliary voltage. Refer to
Cooling Fans, page E-E-32 when
using separate ac fans, (Frame H units).

Main contactor coil
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: When using a Slave Relay, the contacts of the Contactor Control Relay
are internally suppressed by a series connected resistor (680 Ohms) and
capacitor (33μF) to protect the relay contacts. Users should be aware that
when the Contactor Control Relay is “De-energised”, a leakage current of
approximately 2mA @ 220V can be expected and this should be considered
when interfacing to these terminals. Typically, there could be the energisation
of very sensitive relays.

Neutral
This terminal is internally connected to the auxiliary supply neutral and
provides a convenient connection point for the contactor coil neutral
connection.
