Signal connections
CAUTION:
Do not use contactors which have built in ‘economiser’ circuits, the internal circuits
are not compatible with the controller and may cause malfunction or damage. The same power
reduction can be achieved with a standard coil by using the configurable pull-in and hold voltage
settings.
Signal connections are made to Gen4 via a 35 way AMPSeal connector.
Figure 9 Customer Connector
Pins are protected against short-circuits to the battery positive or negative terminals.
NOTE: Please see Tyco Application Specification 114-16016 and Instruction sheet 408-3229
before assembling the AMPseal connector.
Inserting contacts into connector housing pierces the sealing diaphragm to make the seal to the
wire. To maintain IP rating, unused positions must be sealed with appropriate hardware
(available from Tyco) if a contact is inserted and then subsequently removed. It is recommended
that Tyco strain relief 776463-1 is used (especially for applications where the connector is less
than fully populated) to reduce change of ingress through connector body.

1 Key switch
in Power
From ‘dead’ side of key
switch via suitable fuse
7A
(Total of all
contactor
output
currents plus
1.0A) This input supplies power
from the battery for all the
logic circuits.
The unit cannot operate
without “Key switch in”
supply.
Pins 1 and 6 (and 10 on
Size 4 & 6 models) are
connected together
internally and can be used
individually or in parallel.
2 CAN
termination Comms To terminate a Gen4 CAN node link pin
2 to pin 24. This connects a 120
Ω
termination resistor, mounted inside the
controller, across the CANbus.
Make the connection only if
the Gen4 is physically at the
end of the CANbus network
(see ‘CANbus termination’
on page 3-13.
