7.2.2 – Connecting the Remote Keypad
1) The RJ45 cable that is supplied with the remote keypad has two ferrites installed on it to ensure
EMC compliance. Plug the end with the thinner ferrite into the Communication Card primary
RJ45 socket.
2) Secure the ferrite to the starter using a cable tie.
3) Set Communication Card jumpers J1–J5 as shown in Network Connections drawing below.
4) Mount the Keypad using the screws provided and plug the other end of the cable, with the
larger ferrite, into the SR44-KPD Remote Keypad. (SR44-KPD mounting dimensions are shown
on the reverse side of this page.) (Use RTV sealant at mounting holes “A” if NEMA 4X rating is
required.) (Remote keypad is NEMA 4X; soft starter is not.)
The starter can now be controlled by the Remote Keypad when the “Local/Remote” switch is
placed in “Remote”. This setting disables the integral keypad on the cover of the starter.
Switching to “Local” disables the Remote Keypad and enables the integral Local Keypad.
Remote Keypad requires installation of an SR44-RS485 communication card.
The Remote Keypad and the soft starter’s integral Local Keypad are mutually exclusive.
Only one function can control the starter at a time.
Switching to “Local” will always disable remote control of the starter.
