Short description

The EEM-MA400 is a highly accurate energy meter for measuring electrical parameters in low-voltage systems up to 500
V AC. It is designed for front-panel installation and supports the measurement, counting, and display of all electrical pa-
rameters in single, two-, and three-phase networks with and without neutral conductor (symmetrical and asymmetrical).
The buttons located on the front of the device allow fast, direct access to the required parameters as well as device con-
figuration. The device can also be configured by means of the integrated web server if an Ethernet connection is used
and can be extended with a communication module.

Safety and warning instructions

The "attention symbol" on the device label means:
Read the installation note in its entirety. Follow the installation note to avoid impairing the intended protection.
For additional information, please refer to the corresponding user manual at www.phoenixcontact.net/catalog.
Only qualified specialist personnel may install, start up, and operate the device. National safety and accident pre-
vention regulations must be observed.
When working on the device, always disconnect it from the power supply. Short circuit the secondary side of each
current transformer.
Use an appropriate voltage measuring device to ensure that no voltage is present.
Mount all equipment, doors, and covers before switching on the device again.
Installation should be carried out as described in the installation instructions. Access to circuits within the device is
not permitted.
The device does not require maintenance. Repairs may only be carried out by the manufacturer.

Connection notes

Provide a switch/circuit breaker close to a device and ensure it is labeled as the disconnecting device for this de-
vice.
Provide overcurrent protection (I ≤ 16 A) in the installation.
Observe the maximum permissible values for the device supply (IEC/CE: 440 V AC/420 V DC; UL: 264 V AC/275
V DC), mains frequency (50/60 Hz), maximum voltage at connection terminal blocks (520 V AC phase/phase or
300 V AC phase/neutral conductor).
Observe a maximum current of 6 A at the power supply connection terminal blocks (I1, I2, and I3)
