Setup and adjustments
Setting the ZEC510 device address
Before you apply power or operate the ZEC510, you must set a valid and unique device address for
the controller on the bus. Ensure that your system meets the following prerequisite configuration
and complete the addressing steps.
Prerequisites
• Identify the addresses when you design the system before the installation so that the rest of
the devices on the bus do not conflict with the address you select for the ZEC510.
