Installing the Remote Cable
Refer to the following figure to install the remote cable to extend the keypad cable length.
If a “Line Check” message is displayed on the keypad display and the keypad is not operating
correctly after installing the remote cable, check the cable connection on both sides.
Do not extend the keypad cable using a third-party extension cable. The keypad may not operate
correctly due to voltage drop and electromagnetic interference.
• Ensure that the cable length between the keypad and the inverter does not exceed 10 ft
(3.04 m). Cable connections longer than 10 ft (3.04 m) may cause signal errors.
• Install a ferrite clamp to protect signal cables from electromagnetic interference (Ex. Wurth
Electronics ferrite clamp PN742732).
