SYSTEM OVERVIEW
The Electric Vehicle Master Controller (EVMC) is offered pre-mounted onto a back-panel assembly
and is supplied as is or installed into a NEMA-3R electrical enclosure. The two electrical configurations
available for back-panel connection to input powers are (1) Single Input or (2) Direct Input. System
overview and installation instructions are detailed separately below. Both products utilize the same
Control Unit and software.
EV-MASTER CONTROLLER, SINGLE INPUT PRODUCT CONFIGURATION:
Model Numbers:
CS-EVMC-7700-4 EV-Master Controller, Single Input
CS-EVMC-7700-4-E EV-Master Controller, Single Input, in NEMA-3R Enclosure
As shown in figure 1, the EVMC distributes input power from a single 2-pole input line in a sequential
fashion to supply power to four 32A level-II car charging stations or eight 16A level-II charge stations.
This configuration is optimal for fleet charging or other daily use applications like an office or hotel,
where users will be connected for several hours.
Figure1: Schematic for single input EVMC system showing installation and the sequential rotational sharing
of chargers connected to the device. Note: Typical input power is single phase 2pole. Input line 2 is not
shown in figure above but connects directly to all outputs via a common input bus bar. See warning 3
regarding required disconnect during service.
The EVMC controller cycles through a 4 channel switching process according to the default and/or
user defined parameters. During operation the EVMC will detect if an electric vehicle is connected to
charge station as it cycles. If no vehicle is detected or if the vehicle has a full charge, the controller will
automatically move to the next charge station to maximize charge times for all vehicles and ensure all
vehicles are charged over the work day.

EV-MASTER CONTROLLER, DIRECT INPUT PRODUCT CONFIGURATION
Model Numbers:
CS-EVMC-7700-4D EV-Master Controller, Direct Input Configuration
CS-EVMC-7700-4D-E EV-Master Controller, Direct Input Configuration, in 3R
Enclosure
As shown below in figure 2, the direct input product configuration has individual 2-pole power inputs
for each of the four channels of the EVMC controller. Unlike the single input configuration, there is no
common bus bar for shared rotational distribution of load. With the direct input configuration the
system can be set to an “all-on” software mode, where all charge stations are energized allowing cars
connected to a charger on the system to charge in an on-demand fashion. However, during peak rate
times or during off-peak parking times, the system can be set to a rotational mode, activating one
charge station at a time (see note in fig2 below) limiting total system load to that of an individual
charger rather than all 4 chargers at once. This allows charge systems to avoid costly peak rate
charges that boost electrical rates from cents per kWh to multiple dollars (See table 1)
Figure 2: Schematic of Direct Input product configuration. The back panel has separate input terminals for each
switched channel. Up to 4 separate 2-pole input lines can be controlled. Note: Switching occurs only for one line of the
2-pole input, the second line is not switched and connects directly to each output as shown in figure, see warning 3
regarding required disconnect during service.

771-00010 A1 / 1014374 Page 16 of 23
Figure 10b: Settings page, continued.
The Outlet Settings page is for identifying the outlet and for designating rotational priority of the channel. By
checking on the PREFERRED OUTLET box, the system will place the selected channel as a priority in the switching
sequence. When this box is not checked for any outlet, the rotational sequence for the unit will be 1-2-3-4-1-2-3-4-,
etc. However, if the PREFERRED OUTLET box is checked for channel 1, the rotational sequence for the unit will be: 1-
2-1-3-1-4-1-2-, etc. In this case, channel 1 is charging 50% of time no matter how many cars at charging.
Select the ENABLE CYBER DUAL CHARGE FEATURE in the Outlet Settings page if a channel is to power two 16A
charge stations. If a channel is only powering one 32A charge station or one 16A station, leave the ENABLE CYBER
DUAL CHARGE FEATURE box unchecked (default setting). If this function is not selected when two 16A charge
stations are connected, a system error will occur when the system reports an increased load level resulting from a
car connecting to the second charger on the channel during a given charge cycle.
The ROTATION INTERVAL box sets the delay time the system resides at each outlet to detect for a connected car.
The default setting is 30 seconds. If a channel is connected to a shared charging unit, select 60 seconds to allow the
charger software to reboot and adjust to load.
The SNMP Settings and SNMP Trap Settings are modified only for applications where the unit is being monitored
separate Management Software system and customization of SNMP is required. In most typical installations, leave
at default settings.
