3.6 Connecting the 24V Power Supply
The Maestro requires 30 W at 24 VDC ± 20% when turned on. Any isolated power supply that
can supply that power is acceptable.
Connect the 24 VDC output from the power supply to the 24v port on the Maestro using the
3-pin power plug provided.
Notes for 24 VDC supply connections:
ƒ Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.
ƒ The source of the 24 VDC must be isolated.
ƒ Before applying power, first verify the polarity of the connection (protected).
