General Safety Information
Overview
NOTICE:
It is extremely important that you read, understand and follow the warnings and safety
regulations carefully before handling a Xylem product. They are published to help prevent
• personal accidents and health problems
• damage to the unit
• product malfunction.
Xylem assumes no liability for either bodily injuries, material damages or economic losses
beyond what is stated in this chapter.
Environment
The unit must be installed in an environment that is
• sheltered
• wellventilated, and
• nonhazardous.
Temperature
The unit must be used at a temperature within the minimum and maximum rate defined in
accompanying technical data.
Disturbance
Ensure that equipment causing serious disturbance is suppressed in the best possible way.
User Safety and Health
Introduction
All government regulations, local health and safety directives must be observed.
General electricity precautions
All danger due to electricity must be avoided. Electrical connections must always be
carried out in compliance with the
• standard connections shown in the product documentation that is delivered together
with the product, and
• electrical regulations locally in force. Reference: For details, consult the regulations of
your local electricity supplier.
Ground the unit: Ground the unit before carrying out any other operation. The electric
pump motor and the panel must be connected to an efficient grounding system in
compliance with the electrical regulations locally in force.
Disconnect the power supply: Always disconnect the power supply before proceeding to
carry out any operation on the electrical or mechanical components of the unit or the
system. Isolate the power supply before opening the pump.
Harmonic Interference
Care must be taken to avoid harmonic interference from VFD drives, etc. General
guidelines include keeping 24VDC signal wire separate from high voltage wire (120VAC
and above) in wire trays, shielding cable that must remain in the same cable trays as high
voltage wire, and always using shielded cable for analog signals.

High Voltage!
Check rated data: Before starting the installation work, check that the rated data of the
automatic control panel is suitable to the mains power supply and the rated data of the
pump.
Isolate power supply before troubleshooting: All trouble shooting must be carried out with
the power supply isolated. If not, the pump could start unexpectedly.

Mount the Unit
Before the installation
Pay attention to the following before mounting the unit:
• Install the unit in a metal cubicle if the environment is considered to be likely to cause
disturbances.
• Apply the general rules on the separation of power and signal cables inside the
cubicle or in cable ducts. Insufficient separation increases the risk of disturbances and
makes service and maintenance more difficult.
• Make sure that the temperature range of the cubicle will be between 32 and 122°F
during operation.
Mount the operator panel
Follow these steps to mount the operator panel in an equipment cabinet.
Table 2
Step Action
1 Draw the opening to be made in the panel door according to the illustrations below this table.
2 Mark the locations of the six holes for the screws that will secure the frame to the panel door. Drill
the screw holes with a 5 mm drill.
3 Drill a small pilot hole in each corner of the intended opening.
4 Open up the holes with a 10 mm drill. Make sure that the holes are not outside the opening you
have drawn.
5 Make an opening for the operator panel in the panel door using a jigsaw .
6 Place the operator panel in the opening.
7 Fit the washers and nuts, and tighten them firmly.

Mount the I/O unit
Follow these steps to mount the I/O unit.
Table 3
Step Action
1 Locate the unit as far as possible from incoming main power service.
NOTICE:
Avoid locating the unit close to contactors, solenoid valves and similar equipment. The distance
from such units should be at least 11.8 inches
2 Locate the 24VDC power supply unit and the battery unit (if any) close to the RTU.
NOTICE:
Note! The distance between them should be as small as possible, not more than 19.7 inches
3 Mark the four holes for the mounting screws and drill with a 4 mm drill.
4• Screw the screws half way in.
• Hang the I/O unit on the screws.
• Tighten the screws firmly.
5• Connect the cable supplied between the operator panel and the I/O unit.
• Secure the cable so that it will not be crimped.

Avoid Electric and Magnetic Field
Disturbances
Introduction
In the installation of electronic measuring and control systems, it is important to run the
cables and select the cable types in such a manner that the system will be affected as little
as possible by electric and magnetic field disturbances.
Sources and susceptibility
Sources: Potential sources of disturbance include
• Relay Coils
• Solenoid Valves
• Contactors
• Thyristor Units
• Earth (ground) currents
• Static Discharges.
• Variable Freqency Drives (VFD’s)
Susceptibility: The susceptibility to disturbances varies with the electrical environment, for
example:
• Cable Length
• Screening (shielding)
• Electrical noise suppression installation (line reactors, power filters, etc)
Overvoltage protection
Xylem recommends that overvoltage protection with lightning protection should be used
both for the mains power supply to the power supply unit and for the telecommunications
cable. This protection will make the product less sensitive to overvoltage and will therefore
enable it to be used in a more difficult environment.
The overvoltage protection for the mains power supply should be connected in series with
the mains power supply connection.
The overvoltage protection for the telecommunications cable should be in series with the
telecommunications cable.
