3. UNIT INSTALLATION
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the unit safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, use the
necessary personal protective equipment, and pay attention to the various warnings
indicated in this instruction manual.
The CEM-C10 unit must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measuring systems switched off before handling,
altering the connections or replacing the unit. It is dangerous to handle the unit while it is powered.
Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal injury and
damage to installations.
The manufacturer of the unit is not responsible for any damage resulting from failure by the user or
installer to observe the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
If an anomaly or malfunction is detected in the unit, do not use the unit to take any measurements.
Inspect the work area before taking any measurements. Do not take measurements in dangerous ar-
eas or where there is a risk of explosion.
Disconnect the unit from the power supply (unit and measuring system power supply)
before maintaining, repairing or handling the unit's connections.
Please contact the after-sales service if you suspect that there is an operational fault
in the unit.

4. OPERATION
The CEM-C10 is an energy meter capable of measuring:
 Imported and exported active energy and reactive energy in the four quadrants.
(according to version).
 Active and reactive power (according to version).
 RMS voltage and current
 Power factor, PF
4.1.- KEYBOARD FUNCTIONS
The CEM-C10 has 1 key that allows you to browse the different screens and configure the unit.
Key functions on the measuring screens (Table 4):

4.2.- DISPLAY
The unit has an LCD where all parameters are displayed.
The display is divided into three areas (Figure 5):
Figure 5: CEM-C10 Display areas
Data line, displaying the values measured by the unit.
Units, where the unit of the magnitude being viewed is shown.

Indicators, which shows other parameters:
Indicates that the energy being viewed is generated.
Indicates that the energy being viewed is consumed.
Indicates that the energy is inductive.
Indicates that the energy is capacitive.
COM, indicates that there is a communications module connected. It flashes when the
communications are established.
L1 - L2 - L3 - Indicates the presence of voltage in each phase, with its corresponding current
direction:
“ - “ is used to show the power yielded to the network.
“ “ is used to show the power absorbed by the network.
4.3.- LED INDICATORS
The unit has two verification LEDs:
To verify the active energy.
To verify the reactive energy (according to version).
The weight of the LEDs is 1,000 imp/kWh(kvarh).
The LEDs will remain lit when the current lower than the energy meter start-up current. Once the start-
up current is exceeded (due to active or reactive power consumption) the LEDs are turned off and emit
impulses that are proportional to the measured energy.

4.4.- DISPLAY MODES
The CEM-C10 has 2 display modes:
Standby mode display
Reading mode display
4.4.1. STANDBY MODE DISPLAY
With the display in standby mode, all of the information is presented in cyclic form without any need
to perform any action on the CEM-C10 keyboard.
Six different parameters are viewed in this mode, see Table 5, in which they alternate every 6 seconds.
The unit is in this mode by default when none of the keys are pressed.
Short press the key to stop the cyclic movement of the parameter being shown at the time.
From then on, short press the key to browse all the parameters defined in Table 5.
