senva EM-RS485 Installation Instructions Manual

INSTALLATION INSTRUCTIONS
Protocol Energy Meter
EM-RS485 and Current/Voltage Transducers
The EM-RS485 is a three channel meter, capable of monitoring
single-phase, two-phase and three-phase systems, as well
as 3 independent single-phase systems with one meter.
The EM-RS485 meter offers BACnet MS/TP and Modbus RTU
protocols and 2 pulse inputs to maintain flexibility during
installation and operation. The EM-RS485 is compatible with
all sizes of current/voltage transducers (CVTs). With the EM-
RS485 intelligent meter technology, the device self-configures
baud rate, serial format, protocol, and address (BACnet only) -
eliminating additional configuration steps.
Each CVT is independently calibrated to measure and digitally
communicate power values to the meter. The CVT's flexible
Rogowski coil makes installations less burdensome. The
voltage connections are made directly into each CVT - keeping
all high voltage away from the meter. Each CVT is rated from 90
to 600VAC.

codes.
!
WARNING
Failure to follow these instructions may cause injury, death or
equipment damage.
• The EM-RS485 and CVT sensors are designed to be used as a
system. DO NOT connect anything other than a Senva CVT sensor
to the RJ-11 jacks on the meter base.
• If product is used in a manner not specified by the manufacturer,
the protection provided by the product may be impaired.
No responsibility is assumed by the manufacturer for any
consequences arising out of the use of this material.
WARRANTY DISCLAIMER
DO NOT modify the length of the CVT Data Communication Cable.
Field modifications to the CVT Data Communication Cable will void
factory warranty.
