Safety symbols and messages
Read these instructions carefully and look at the equipment to become familiar with the device before trying to install,  operate, service or maintain it. The following special messages may appear throughout this bulletin or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure.

Risk of electric shock

• ANSI symbol.
• IEC symbol.

The addition of either symbol to a “Danger” or “Warning” safety label on a device indicates that an electrical hazard exists, which will result in death or personal injury if the instructions are not followed.

Safety alert

This is the safety alert symbol. It is used to alert you to potential personal injury hazards and prompt you to consult the manual. Obey all safety instructions that follow this symbol in the manual to avoid possible injury or death.

Safety messages

• DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
• NOTICE is used to address practices not related to physical injury.

Precautions

Storage
Sepam may be stored in its original packaging in a closed sheltered location:

• ambient temperature: -25 °C to +70 °C (or -13 °F to +160 °F) humidity y 90 %. Periodic checking of the environment and the packaging on a yearly basis is recommended.

Commissioning
Once installed, the Sepam must be energized as soon as possible, especially in a damp location (humidity u 90 %). Storing an unenergized and unpackaged Sepam for a long period may damage the unit.

Documentation

Quick Start

The Quick Start document supplied with each Sepam has two functions:

• a concise installation and commissioning guide for OEMs
• a reminder for operators.

It is advisable to keep it near Sepam. The certificate of conformity on the last page may be detached and kept with the installation documents.

Operation manual
Consult the operation manual (reference SEPED303003EN) for detailed information on the installation, use, commissioning and maintenance of Sepam series 80. These documents can be downloaded from www.schneider- electric.com

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Turn off all power supplying the Sepam and the equipment in which it is installed before working on it.
• Always use a properly rated voltage sensing device to confim that the power is off.
• Replace all devices, doors, and covers before turning on the power to this equipment.
• Before energizing the power equipment, replace all barriers and covers.
• Apply appropriate personal protective equipment and follow safe electrical work practices. See local regulations.
• This equipment must only be installed and serviced by qualified electrical personnel.

Failure to observe these instructions will result in death or serious injury.

DANGER

HAZARD OF ELECTRIC SHOCK, ELECTRIC ARC OR BURNS

• Only qualified personnel should install this equipment. Such work should be performed only after reading this entire set of instructions.
• NEVER work alone.
• Turn off all power supplying this equipment before working on or inside it. Consider all sources of power, including the possibility of back feeding.
• Always use a properly rated voltage-sensing device to confirm that all power is off. Failure to follow these instructions will result in death or serious injury.

Installation of MES120 modules

Installation of a MES120, MES120G or MES120H module on the base unit

• Insert the 2 pins on the MES module into the slot 1 on the base unit
• Push the module flat up against the base unit to plug it into the connector H2
• Partially tighten the two mounting screws 2 before locking them. MES120 modules must be mounted in the following order:
• If only one module is required, connect it to connector H1
• If 2 modules are required, connect them to connectors H1 and H2
• If 3 modules are required (maximum configuration), the 3 connectors H1, H2, and H3 are used.

Note: the CCT640, CCA630, CCA634 and CCA671 connectors are removable and screw-lockable.

Installing the terminal block identification label
A sticker showing the rear panel of Sepam and terminal assignments is supplied with each base unit to facilitate the installation and connection of Sepam and the MES120 input-output modules. You may stick it in the location of your choice, e.g. on the side of a MES120 module or on the right-hand side panel of Sepam.

Access to measurements
The measurements are split into 2 categories, accessed via the following keys:

• : key: access to measurements
• : key: access to switchgear, network, and machine diagnosis data. The values are presented in a series of screens as shown in the diagram below. Each time the user presses the key, the system moves on to the following screen in the loop.

Operation
After fault tripping of the protection function (e.g. phase overcurrent):

• the Trip indicator goes on
• the I>51 indicator goes on
• the UMI screen displays:
  • a “Phase fault” message
  • the date and time of the appearance of the fault

The key may be used to change the set point and time delay of most of the protection functions in service in Sepam. It is accessed via a menu that lists the protection functions used. The user selects the protection function to consult or modify the setting of each of the units used for the function.

Selecting the control mode
By key-switch on the front of the mimic-based UMI: REMOTE, LOCAL, TEST. Local switchgear control All the devices for which the opening and closing are controlled by Sepam may be controlled locally via the mimic based UMI. The most common interlocking conditions may be defined by logic equations or by Logipam.

Operating procedure:

• select the LOCAL control mode on the key-switch
• select the device to be controlled by moving the selection window using the keys Sepam checks whether local control of the selected device is authorized and informs the operator (selection window with a solid line).
• selection confirmation for the device to be controlled by pressing the key (the selection window flashes). device control by pressing:
  • key : open order
  • or key : close order.

Commissioning

Energizing
The Sepam supply voltage must be between 24 V DC and 250 V DC. After Sepam is switched on, it performs the following initialization sequence, which takes approximately 5 seconds:

• ON and LEDs switch on, “Sepam” on screen
• LED switches off
• watchdog contact picks up

The first screen displayed at the end of the sequence is the phase current metering screen.

Diagnosis
At the end of the initialization sequence, the LED should be off.

• LED flashing: minor fault detected, Sepam in downgraded operation
• check the connection of the MET148-2, MSA141 and MCS025 modules.
• LED steadily on: major fault detected, Sepam in failsafe position
• check that the CCA630, CCA634 or CCA671 input connectors are plugged in
• check the connection of the strap between terminals 19 and 20 of connector (DPC, detection of plugged connector function).
  • If the  LED is still not off, refer to the “Maintenance” chapter of the operating manual.
  • If the “LOW BATTERY” message appears, check that the battery is present and in the correct position (check that polarities match).

Parameter setting with SFT2841
The SFT2841 parameter setting and the operating tool is essential to:

• prepare Sepam parameters
• to prepare protection and control function settings.
• transfer the parameters and settings into Sepam.

Passwords
Sepam has two 4-digit passwords:

• parameter setting password, which allows entry of all general parameters and protection settings
• protection setting password, which only allows entry of protection settings
