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.

4 NETWORK DATA
Consumed Digital Data – This data is sent from the controller to the SmartBlock. For typical
applications the I/O configuration setup in Cscape will automatically populate this data. For more
advanced applications you may use NetPut functions to write this data. Please see the advanced
programming guide MAN0880 for more details.
Bit
Description
1
Q1 default
2
Q1 override
Upon module stop / timeout, if Q1 override is true, Q1 is set to Q1 default, otherwise the Q1
value is held. This override / hold polarity is consistent with OCS / Cscape usage but the
reverse of the legacy analog hold / override polarity in word 5.

Frequency Source, Set for phase B, Clear for phase A or C
4
Frequency Source, Set for phase C, Clear for phase A or B
If Clear
Always accumulate Watt-Hours
5
If Set
Do not accumulate Watt-Hours if load is under 0.005% of full scale to avoid meter
creep due to slight zero errors
6
Set to report period instead of frequency in AI13 / AI14
17
Relay output, set to ON to close N.O. and open N.C contacts.
23
Set to ON to clear KWhr, set to OFF to re-enable KWhr accumulator
24
Set to ON to clear Status flags, set to OFF to re-enable Status flags
Produced Digital Data – This data is sent from the SmartBlock to the controller. Normally this data is
mapped into specific registers in the I/O configuration in Cscape. For advanced applications NetGet
functions can be used to obtain this data. Since this data is broadcast to all controllers on the network
additional controllers can use NetGet functions to obtain this data as well.

5 INSTALLATION / SAFETY
Warning: Remove power from the SmartBlock, CAN port, and any peripheral equipment
connected to this local system before adding or replacing this or any module.
Use the following wire type or equivalent:
• Belden 8917
• 16 AWG or larger
When found on the product, the following symbols specify:
WARNING: This unit should be located so that it is not accessible without the use of a tool.
WARNING: If this device is used in a way not specified by the manufacturer the safety provided
may be impaired.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of fire
and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or loss
