Installation
Installing the enclosure
The HU250 module is fastened to a DIN rail. No tool is needed for mounting.
Simply clip it in order to fasten it as shown below.
Installation of a modem box
Each modem box can be installed or interchanged easily and quickly in the HU250. The modem box is installed in the factory, but if necessary it is possible to dismount it and replace it with another type of modem. To install a modem box:
- Insert the SIM card(s) on the bottom of the modem (preferably with HU250 switched off).
- Install the modem box in the required slot on the HU250 (port 1 or port 2 slot).
- Press the front panel to insert the rear panel connector in the HU250 (be careful not to over-force during insertion).
- Tighten the screw on the front panel using a flat or Phillips-head screwdriver to fasten the modem box to the HU250.
To withdraw a modem box from its slot, perform the operation in reverse.
Note: When changing a modem box it is also necessary to have the configuration changed by an expert using the Easergy Builder advanced configuration tool. To do so, refer to the Easergy Builder user guide.
Operation
Once the HU250 has been powered up, some indicator lamps on the front panel may be lit to indicate certain operating states.
The buttons allow the user to perform actions. These indications and actions are summarized in the table below:
| Part | Description of indications and actions |
 | HU250 states 1.1 HU250 operating 1.2 Equipment status 1.3 WI-Fl access operating (activated by Local mode) 1.4 Communication status with modules (SC150. LV150. PS50….). |

Note: Refer to the table opposite for the meaning of the flashing states and the various possible colors for indicator lamps. Some indicators can be customized by configuration.
3G or 4G modem
This modem allows a SIM card to be inserted in one of the two available SIM card slots, without there being any difference at the operating level.
The GPS and GSM antenna connectors are accessible on the front of the modem.
Mounting the GPS antenna:
- Attach the GPS antenna to the wall of the substation (preferably outside).
- Connect the antenna cable to the modem connector marked «GPS».
Note: The GSM antenna requires no outside mounting. It is a short antenna connected to the modem itself. This antenna is installed in the factory.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- Wear your personal protective equipment (PPE) and comply with safe electrical work practices. See NFPA 70E in the USA or applicable local standards.
- Only qualified persons should install this equipment. Such work should be performed only after reading this entire set of instructions.
- Switch off the electric power supply of the HU250 and of all the devices to which the HU250 is connected before any handling or replacement operation.
- 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.
Power supply
The HU250 includes two connectors to connect the power supply. These two connectors are connected together internally in the HU250. Having two power supply connections can facilitate the connection between the modules. No strapping is necessary. Connect the HU250 as shown in the following diagram.
Parameters setup
Installation of the HU250 module requires no parameters setup. This is performed during the commissioning/ configuration stages. Refer to the User manual and the T300 Quick start for any further information.
Identification
The serial number of the HU250 is formed as follows: Year – Week – Work order e.g. 15340265 (265th product manufactured, week 34 of the year 2015)
Grounding
The HU250 module must be connected to the ground via the mounting DIN rail. The DIN rail helps ensure electrical continuity (preferably use a DIN rail in 304L stainless steel to withstand the climatic conditions).
NOTICE
HAZARD OF INCORRECT CURRENT MEASUREMENTS
- The DIN rail on which the HU250 is installed must be grounded and of metallic type and must comply with electrical continuity in all climatic conditions.
- If the HU250 is installed on a PS50 power supply module, the grounding of the module is done via the PS50’s DIN rail, which must be grounded via a dedicated terminal near the PS50 power input connector. Refer to the Installation Guide of the PS50 power supply.
Failure to follow these instructions can result in equipment damage.
