All live DC and Common connections are made to the connectors at the rear of the unit as
shown in Fig 2 and Fig 2.1.
For 1-8 load breakers 8Awg/10mm
2
terminals are used whereas for 9-16 load breakers,
10 Awg/6mm
2
terminals as shown in Fig 2 and Fig 2.1.
The battery terminals shown can accept cables up to 2 Awg/35mm
2
.
The internal battery cabling goes directly to the circuit breaker, then via a Low Voltage
Disconnect relay and current shunt to the internal live bus. This can be seen on the
wiring diagram at the rear of this manual & in Fig 5.
Ensure cables are strain relieved by utilizing the cable tie slots provided as shown in Fig 2.

Alarm/Ancillary Cabling
Alarm and communication cables terminate directly into the terminals of the Energy
Manager. These terminals are accessible by pulling the monitor forward to expose
connections as shown in Fig 3, Fig 3.1, Fig 3.2 & Fig 3.2a. When routing the cables, ensure
they are kept away from the AC and DC power cables when possible.

Temperature Sensors
Uncoil the battery temperature sensor tie wrapped to rear of shelf and place in the middle of
the middle battery string. If the lead is not long enough, ordinary 2-core copper (approx. 18
AWG/0.75mm
2
) wire can be used as an extension. The purpose of the battery temperature
sensor is to monitor the ambient temperature of the batteries over long periods of time and
adjust the rectifier output (float) voltage accordingly. As a result, it is not necessary to have
the temperature sensor touching the batteries. If the Battery Temperature Sensor is removed
a “battery temp fault” alarm is generated.
The “Ambient” temperature sensor (optional) can be used to monitor the temperature in
another location if required. Temperature sensors from the older Sm3x controllers are not
compatible with the EM4x controller.

UI
The energy manager is configured via a web browser-based user interface (Web UI).
There are two methods to access the Web UI:
•
Ethernet connection from the J305 ethernet connector
•
Front panel micro-USB local connection
