Warranty and Safety Conditions*

WARNING:
The electronics in the power supply system are designed for indoor, clean environment. When installed in dusty and/or corrosive environment, outdoor or indoor, it is important to:

• Install an appropriate filter on the enclosure door, or on the room’s air control system
• Keep the enclosure door closed during operation
• Replace the filters on a regular basis.

Important Safety Instructions and Save these Instructions.

• The inverter system/rack can reach hazardous leakage currents. Earthing must be carried out prior energizing the system. Earthing shall be made according to local regulations.

• Prior to any work conducted to a system/unit make sure that AC input voltage and DC input voltage is disconnected.

• CAUTION – Risk of electric shock. Capacitors store hazardous energy. Do not remove cover until 5 minutes after disconnecting all sources of supply.

• CAUTION – Disconnection of the DC source is required to de-energize this unit before servicing.

• Maximum operating ambient temperature is 40º C (104º F).

• AC and DC circuits shall be terminated with no voltage / power applied.

• Some components and terminals carry high voltage during operation. Contact may result in fatal injury.

• Warning labels must not be removed.

• Never wear metallic objects such as rings, watches, bracelets during installation, service and maintenance of the product.

• Insulated tools must be used at all times when working with live systems.

• When handling the system/units pay attention to sharp edges.

• ESD Strap must be worn when handling PCBs and open units.

• The inverter system/rack is not supplied with internal disconnect devises on input nor output.

• REG systems can be seen as independent power sources. To comply with local and international safety standards the output Neutral and PE are bonded internally in the module.

• By-Pass system that have no AC input wired and connected to comply with local and international safety standards N (output) and PE shall be bonded. The bonded between N output and PE must be removed once the AC input is being connected.

• The safety standard IEC/EN62040-1 requires that, in case of output short circuit, the inverter must disconnect
  in maximum 5 seconds. However, if the parameter is set at a value > 5 seconds, an external protection must be provided in order that the short circuit protection operates within 5 seconds. Default setting is 60s.

• Step 2: Fix the module with M5 nuts on all four sides, as shown below.
• Step 3: Perform the above processes for fixing the second module in another slot of the sub-rack.

Wiring
Caution:
The e-one has internal fuses on DC inputs.
Those device do not protect the upstream cables connected to DC inputs and upstream breakers or fuses shall be set up in accordance with DC wires ratings, to meet the local national electrical code standard.
All breakers, cables and wires should be classified for min 90°C (194°F) operation. Matching respectively Line / Neutral feeder to Line / neutral input connections is required.
Before any intervention on the e-one input, operator has to make sure that power is switched off on DC leads.
Some safety labels are stuck on the e-one. They must not be removed.
The insulation cover of conductors must meet the local and international standards and the cross section must be related to the upstream protections.
REG Model – Termination Details
In e-one REG models:

• DC conductors connected to screw terminals must be tied with torque between 1.2 and 1.5 Nm.
• Ground conductors connected to copper plates with bolts must be tied with torque between 5 and 7 Nm.

DC Input connection
Integrator must provide branch circuit protection with breaking capacity related to short circuit capacity of upstream DC source.

• DC Breaker must be installed close enough to permit easy “Break Before Make”.
• Appropriate type can be chosen within the table here below.
• e-one is supplied with safety labels, which must be applied to the breaker in a visible way.

The insulation cover of connecting cables must meet the local and international standards and the cross section related to the upstream protections.

| Model| DC input current at 40 Vdc| DC breaker Recommended| Cable size| Max size
---|---|---|---|---|---
e-one 3 – 48/230| 9 A| 16 A| 2.5 mm²| 1 x 2.5 mm² per pole

The +DC 48V supply could be earthed or work in float mode.
Adapt the breaking capacity of your breaker in relation to your installation (length cable, battery capacity).
AC Output distribution
The e-one unit has a 1x IEC socket on output.
Note: The output Neutral and PE are bonded internally in the module.
Caution:
The e-one should be turned OFF by remote ON/OFF action. Prior any intervention on AC output make sure DC input has been actually disconnected or, no output voltage is present.
Prior any handling of the e-one, wait a few minutes (minimum 5 minutes) for complete discharge of internal capacitors that have been energized.
Output on socket

**| Model| Iout @ 230 Vac| Cable size| Max size**
---|---|---|---|---
e-one 3 – 48/230| 1.52 A| 1.5 mm²| 2.5 mm²

Output Short-Circuit
On output short-circuit, the e-one will push more than 3.2 Amps AC current through the output terminals for 200 ms, and then output stops permanently with a continuous RED indication. So, the module stops after 200 ms of short- circuiting.
Output on IEC socket
IEC output is protected by 3.15 amps fuse (5 x 20 mm).
Remark: e-one without static transfer switch function (REG type) can be seen as independent power sources.
Replacing Fuse
In-case Fuse failure, perform the following steps to replace fuse.
Fuse Details:

Manufacturer| Manufacturer Part Number| Current Rating| Voltage Rating AC| Fuse Size/Group
---|---|---|---|---
Schurter| 0001.2509| 3.15 A| 250 Vac| 5 mm x 20 mm

Fuse will be present at rear side of the system.

• Step 1. By using the Flat Screw Driver gently turn the Fuse holder to 45° in anti clock wise direction.
  The Fuse Holder automatically ejects from the slot. (Fuse holder will not go beyond 45°).

• Step 2. Remove the Fuse holder from the slot.

• Step 3. Replace the appropriate new Fuse in the holder.

• Step 4. Place the Fuse with holder in the slot.

• Step 5. By using the Flat Screw Driver gently push and turn the Fuse holder to 45° in clock wise direction.
  Make sure Fuse holder is locked.

Warning: Risk of electric shock, do not replace the Fuse in system running condition.
Grounding
Earth connection must be done to the point referenced with symbol Input ground must be connected to the appropriate terminal
Caution: Current leakages can reach hazardous values.
For your personal, SAFETY earth connections must be done before energizing the system.
Remote Monitoring and Control
Alarm Connector
There is one free potential changeover contact provided. Maximum wire size is 0.5 mm². It can be used for Alarm indication purposes. It has one Major Alarm relay.
N.B. : Relays are energized while idle (i.e. relays de-energized when event occur).
MAJOR relay provide an open or close free potential contact
Relay characteristics:

• Maximum switching capacity: 1 A @ 60 VDC
• Maximum switching power: 30 W

Remote ON/OFF
e-one system can be remotely activated or stopped (stand-by mode).
