Service Connections
Caution To reduce the risk of fire, connect only to a circuit provided
with the appropriate maximum branch circuit overcurrent protection in
accordance with the National Electrical Code, ANSI/NFPA 70.
For a model ACS-15, use a 15A circuit breaker
For a model ACS-20, use a 20A circuit breaker
For a model ACS-25, use a 25A circuit breaker
Caution This is a single-phase device. Do not connect all 3 phases of
a 3-phase feed !!! You may use any one phase of a 3-phase wye-
connected feed. The center-point of the 3 phases (usually used as
Neutral) must be grounded somewhere in the system. A current-
carrying Neutral as well as a Ground connection are required by the
ACS, as shown in Figure 3.
Caution The phase used must measure 120V to Neutral. Earth Ground
must be connected to Neutral at only one point, usually at the Service
Entry Breaker Panel.
Caution If a 3-phase feed is from a Delta-connected secondary, the leg
used must have a center-tap. That tap must be Grounded. Only a phase
on either side of the center-tapped leg can be used. See Figure 4 below.
Caution Warranty is void if this unit is wired improperly
Warning Only a qualified electrician should perform the installation.
The installation must be performed in accordance with all local electrical
codes and ordinances.
Only 3 wires are connected, but care must be taken that the service transformer
secondary connection is definitely known, and the 3 wires from the main circuit
breaker panel are connected and labeled correctly. Figures 2, 3, and 4 below
show the most common service transformer secondary wiring formats.
Notice that L1, Neutral & Ground are labeled on each diagram. Those transformer
outputs correspond to the same inputs on the ACS. Also, each of the two 3-
phase diagrams shows an L2 and an L3 output, which are not used. Do not
connect more than one phase of a 3-phase secondary to the ACS. This is a
single-phase device.
