Connecting the CoreSense M10

Once the CoreSense™ M10 analytical unit and sensor head are installed, you have to connect the two via
the conduit attached to the sensor head. You also need to supply power to the system.
WARNING
Failing to comply with any of the instructions, precautions or warnings contained herein
is in direct violation of the standards of design, manufacture, and intended use of the
instrument.
ABB assumes no liability for user failure to comply with any of these safety requirements,
which may result in personal injuries and/or instrument damages.

Safety

ONLY qualified personnel may perform the electrical installation of the monitoring system.
In accordance with international safety standards, the monitoring system requires a three-wire power
cord or line typically connected to an electrical panel that provides grounding for the analytical unit and
sensor head.
• CoreSense M10 is an overvoltage category II instrument.
• An external circuit breaker with a 8 A rating or less must be installed on the AC source and labeled
in compliance with your country's national electrical code. Also, if required by this code, a circuit
breaker or switch in the building installation, marked as the disconnect switch, shall be in close
proximity to the equipment and within easy reach of the operator.
• Operators must strictly observe all applicable national regulations with regards to installation,
function tests, repairs, and maintenance of electrical devices.
• Before opening the analytical unit cabinet, disconnect power at the distribution panel circuit breaker.
• Ensure that the equipment and any device or power cord connected to it is properly grounded.
• Make sure that system and transformer grounds are at the same potential.
• ONLY use power cords equipped with a protective grounding terminal.
• Protective grounding connections must be active at all times.
DANGER
The absence of grounding can lead to a potential shock hazard that could result in serious
personnel injury.
If an interruption of the protective grounding is suspected, cut the power to the system at
the plant distribution panel and have the electrical circuit tested.
