The Conext Battery Monitor is a meter for 24 V &
48 V batteries designed for use in off-grid power
systems as a wall/panel/DIN-rail mount device. It
features a local display to selectively show the
voltage, current, consumed amp-hours, remaining
capacity and remaining hours.
The Battery Monitor connects with other Xanbus
devices such as Inverters, Solar Charge
Controllers, Automatic Gen Start & System
Control Panel via Xanbus ports to provide
accurate information about the state of the
connected battery. The Battery Monitor is wired to
the battery through two ports, an analog signal
port and BTS (Battery Temperature Sensor).

HAZARD OF ELECTRIC SHOCK AND FIRE
 Connect only to Safety Extra Low Voltage (SELV) circuits and power sources.
 All wiring must be done by qualified personnel to ensure compliance with all applicable installation
codes and regulations.
 For Indoor Use Only.
 Do not disassemble. No user serviceable parts inside.
Failure to follow these instructions will result in death or serious injury.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
 Remove watches, rings, or other metal objects.
 This equipment must only be installed and serviced by qualified electrical personnel.
 Keep sparks and flames away from the batteries.
 Use tools with insulated handles.
 Wear protective glasses, gloves and boots.
 Do not lay tools or other metal parts on top of batteries.
 Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
See NFPA 70E or CSA Z462.
 Never operate energized with covers removed.
 Energized from multiple sources. Before removing covers identify all sources, de-energize, lock-out,
and tag-out and wait 2 minutes for circuits to discharge.
 Always use a properly rated voltage sensing device to confirm all circuits are de-energized.
Failure to follow these instructions will result in death or serious injury.
DAMAGE TO BATTERY MONITOR
 The shunt must be installed in the negative line. Installing the shunt in the positive line may result in
damage to the Battery Monitor.

Install Battery Monitor in a dry, indoor location away from direct sunlight.
Failure to follow these instructions can result in damage to equipment.
OVERHEATING OF DC TERMINALS AND CABLES
Overheating of the DC terminals or DC cables to dangerous temperatures may occur due to improper
installation.
 Do not put anything between the cable lug and the terminal surface.
 Do not over-tighten connections; observe all recommended torque values.
 Do not apply any type of anti-oxidant paste until after the cable connection is tightened.
 Do not under size cables; install cables sized in accordance with national electrical code
requirements.
 DC cables must have crimped copper compression lugs or crimped and soldered copper
compression lugs; soldered connections alone are not acceptable. Lugs must be rated for use with
fine-stranded cable.
 Do not use coarse-stranded cable; the lack of flexibility may pull DC terminal connections loose.
Failure to follow these instructions can result in death or serious injury.
HAZARD OF ELECTRIC SHOCK
For monitoring lead-acid batteries with a nominal voltage up to 48VDC, maximum terminal voltage is
64VDC.
Failure to follow these instructions can result in injury.
POTENTIAL FIRE HAZARD
To reduce the risk of electrical fire, replace fuse with SAME size, type, and rating ONLY.
Failure to follow these instructions can result in death or serious injury.
Important Safety Information
This Guide is intended for any qualified personnel who need to operate, configure, and troubleshoot the Conext Battery Monitor. Certain configuration tasks should
only be performed by qualified personnel in consultation with your local utility and/or an authorized dealer. Electrical equipment should be installed, operated,
serviced, and maintained only by qualified personnel. Servicing of batteries must only be performed or supervised by qualified personnel with knowledge of batteries
and their required precautions.
Qualified personnel have training, knowledge, and experience in:
• Installing electrical equipment
• Applying applicable installation codes
• Analyzing and reducing the hazards involved in performing electrical work
• Installing and configuring batteries
• Selecting and using Personal Protective Equipment (PPE)
No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.
1. Before using this product, read all instructions and cautionary markings on the unit, the batteries, and all appropriate sections of this manual.
2. Use of accessories not recommended or sold by the manufacturer may result in a risk of fire, electric shock, or injury to persons.
3. The manufacturer recommends that all wiring be done by a certified technician or electrician to ensure adherence to the local and national electrical codes
applicable in your jurisdiction.
4. To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that wire is not undersized. Do not operate the equipment with
damaged or substandard wiring.
5. Do not operate the equipment if it has been damaged in any way.
6. This unit does not have any user-serviceable parts. Do not disassemble the combiner box except where noted for connecting wiring and cabling. See your
warranty for instructions on obtaining service. Attempting to service the unit yourself may result in a risk of electrical shock or fire. Internal capacitors remain charged
after all power is disconnected.
7. To reduce the risk of electrical shock, disconnect both AC and DC power from the equipment before attempting any maintenance or cleaning or working on any
components connected to the equipment. Putting the unit in Standby mode will not reduce this risk.
8. The equipment must be provided with an equipment-grounding conductor connected to the AC input ground.
9. Do not expose this unit to rain, snow, or liquids of any type. This product is designed for indoor use only. Damp environments will significantly shorten the life of
this product and corrosion caused by dampness will not be covered by the product warranty.
10. To reduce the chance of short-circuits, always use insulated tools when installing or working with this equipment.
11. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with electrical equipment.
