regulations governing the usage location must be observed.
1.4.3 General Safety Notes
DANGER!
Life-threatening hazard from electric shock!
There is an imminent life-threatening hazard from elec-
tric shocks from live parts. Damage to insulation or to
specific components can pose a life-threatening
hazard.
– Only a qualified electrician should perform work on
the electrical equipment.
– Immediately switch off the power supply and have
it repaired if there is damage to the insulation.
– Before beginning work at live parts of electrical
systems and resources, cut the electricity and
ensure it remains off for the duration of the work.
Comply with the five safety rules in the process:
– cut electricity;
– safeguard against restart;
– ensure electricity is not flowing;
– earth and short-circuit; and
– cover or shield neighbouring live parts.
– Never bypass fuses or render them inoperable.
Always use the correct amperage when changing
fuses.
– Keep moisture away from live parts. Moisture can
cause short circuits.
WARNING!
Hazards due to insufficient prime mover protection
The engine, turbine, or other type of prime mover
should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown
device(s), that operates totally independently of the
prime mover control device(s) to protect against run-
away or damage to the engine, turbine, or other type of
prime mover with possible personal injury or loss of life
should the mechanical-hydraulic gov-ernor(s) or elec-
tric control(s), the actuator(s), fuel control(s), the
driving mechanism(s), the linkage(s), or the controlled
device(s) fail.

Hazards due to unauthorized modifications
Any unauthorized modifications to or use of this equip-
ment outside its specified mechanical, electrical, or
other operating limits may cause personal injury and/or
property damage, including damage to the equipment.
Any unauthorized modifications:
– constitute "misuse" and/or "negligence" within the
meaning of the product warranty thereby excluding
warranty coverage for any resulting damage
– invalidate product certifications or listings.
NOTICE!
Damage to the control system due to improper
handling
Disconnecting a battery from a control system that
uses an alternator or battery-charging device whilst the
charging device is still connected causes damage to
the control system.
– Make sure the charging device is turned off before
disconnecting the battery from the system.
Protective equipment: nESD wrist band
NOTICE!
Damage from electrostatic discharge
All electronic equipment sensitive to damage from
electrostatic discharge, which can cause the control
unit to malfunction or fail.
– To protect electronic components from static
damage, take the precautions listed below.
1. Avoid build-up of static electricity on your body by not
wearing clothing made of synthetic materials. Wear cotton or
cotton-blend materials as much as possible because these
do not store static electric charges as easily as synthetics.
2. Before any maintenance work on the control unit, ground
yourself by touching and holding a grounded metal object
(pipes, cabinets, equipment, etc.) to discharge any static
electricity.
Alternatively wear an ESD wrist band connected to ground.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic
or Styrofoam cups, cigarette packages, cellophane wrappers,
vinyl books or folders, plastic bottles, etc.) away from the
control unit, modules and work area.

remove the printed circuit board (PCB) from the control cab-
inet unless instructed by this manual.
If instructed by this manual to remove the PCB
from the control cabinet, follow these precau-
tions:
–Ensure that the device is completely voltage-
free (all connectors have to be discon-
nected).
–Do not touch any part of the PCB except the
edges.
–Do not touch the electrical conductors, con-
nectors, or components with conductive
devices or with bare hands.
–When replacing a PCB, keep the new PCB in
the plastic antistatic protective bag it comes

The input of the current transformer ratio is necessary for the indication and
control of the actual monitored value.
The current transformers ratio should be selected so that at least 60 % of the
secondary current rating can be measured when the monitored system is at
100 % of operating capacity (i.e. at 100 % of system capacity a 5 A CT should
output 3 A).
If the current transformers are sized so that the percentage of the output is
lower, the loss of resolution may cause inaccuracies in the monitoring and
control functions and affect the functionality of the control.
