o Remove power from the panel
o Use compressed air, preferably with a line dryer, to blow out the cups.
o Cleaning may also be done using a vacuum cleaner.
o A dry soft brush can be used to loosen debris in the cup prior to blowing it out with
compressed air.
o No CRC or other aerosol cleaning sprays should be used to clean the cups. The
accelerant may damage the cups.
• The NRUs should be inserted individually. The nodes do not need to be oriented as the springs
allow connections around 360°.
o Insert the NRUs as straight as possible. A straight up and down insertion of the NRUs will
avoid damage to the connector cups.
o Use a firm straight downward pressure to push the NRU down onto the panel.

• When initiating an upload or commissioning sequence, if an NRU fails the Connect step with a
“Failed to receive NRU status” error, the NRU may not be contacting the springs of the cup.
o When Charge On is applied to a cup, it will act as a charge panel cup. The NRU will blink
a white LED at first, then start blinking a yellow LED indicating charging.
o The NRU must detect a charge voltage during uploading or commissioning.
o Verify the NRU is seated properly in the slot. If not, pull the NRU out, and seat it again
firmly into the slot.
• Once upload or commissioning has finished, the NRUs can be removed from the panel.
• Do not operate a panel if there is any physical damage to any of the cup connectors, especially
involving the springs.
• Do not apply power to a panel that has a damaged/broken power connector.
• It’s preferable to not remove or insert NRUs in the cup connectors with Charge On applied to
the cup connectors. To prevent accidental shorting, select Charge Off or All Off before
removing or inserting the NRU.
