Inverter Keypad Removal and Installation
Keypad Removal - The SJ200
keypad. To remove the keypad, locate the
retention latch as shown to the right. Press
downward on the latch, while gently pulling
toward you. The keypad will tilt forward, as two
retaining tabs at the bottom edge of the keypad
also hold it in place. Then remove the keypad
from the keypad bay.
Internal LED Indicators / Communications Connector - Refer to the keypad bay in
the illustration below. After removing the keypad, the internal LED viewing window will
be visible. These LEDs indicate status for your convenience when the keypad is
remotely mounted and you are nearer to the inverter location.
The RJ45 connection consists of two parts. The clear plastic RJ45 modular interconnect
makes the connection between the inverter and the keypad. It is easily removed to allow
you to plug a communications cable into the modular connector.

Installing the Keypad - Follow these steps:
1. Remember to install the RJ45 modular interconnect. Otherwise, there will be no
connection to the keypad.
2. Set the bottom edge of the keypad into the inverter keypad bay.
3. Tilt the top edge of the keypad forward. If it stops before seating firmly, DO NOT
force the keypad. You may need to adjust the end RJ45 modular connector slightly
(upward or downward). Then seat the keypad.
4. Make sure the retention latch clicks into place on the inverter housing top edge.
Otherwise, vibration may cause the keypad to loosen in the future.
