Information is subject to change without notice.

The SmartBlock ACM300 is a Power and Energy Monitor that is easy to setup, and provides a variety of
advanced features, including:

• 3-phase Power Monitoring with three
current (0-5A CTs) and voltage inputs
(480V, direct connect or PTs).

• CsCAN CAN network connection
provides a fast flexible communication
path.

• SmartBlock package allows convenient
mounting close to the source to be
monitored

• On board relay allows load shedding,
alarming or other local switching.

2 DIMENSIONS AND INSTALLATION

Network, Power and Grounding:

A single 5 pin connector is used to make both a network connection and power input. A quality class 2
power supply should be used for this product. If the power is run with the network cable, care must be
taken such that the voltage does not drop below the lower supply limit on longer runs.

A quality protective earth ground is required for safe and proper operation. The best protective earth
ground is achieved by screwing the lower left grounding location into a grounded back plate. Alternately
a protective earth ground can be connected to the spade lug.

Please see Horner manual MAN0799 for details on CAN wiring.
