Operational conditions
This section of the document describes basic recommendations for transportation, storing, installation and operation
of WS868-PLE-I radio modules.
4.1
General Operation Risks
The radio modules are electronic devices power-supplied by internal batteries that register rotation of gas-meter
into the internal counter and broadcast radio-messages with actual gas-meter status.
During their operation be aware mainly of the following risks:
4.1.1
Risk of mechanical and/or electric damage
The devices are enclosed in plastic boxes, so that the electrical components are protected from the direct damage
by human touch, tools or static electricity.
The device is intended for using in normal internal environment. The device is designed for mounting directly to
the mechanical counter slot of the gas-meter reserved for remote reading modules. In normal operation no special
precautions are needed, besides avoiding of the mechanical damage from strong pressure or shocks and protection
against excessive humidity.
Installation of the module can be performed only by a person with necessary qualification in electrical engineering
and at the same time trained for this device installation.
4.1.2
Risk of premature battery discharge
The devices are equipped with the long duration batteries. Battery life can be influenced by these factors:
•
storage and operation temperature – in high temperatures the spontaneous discharging current increases, in
low temperature the battery capacity reduces;
•
frequency of broadcasting.
4.2
The condition of modules on delivery
Modules are delivered in standard cardboard boxes. The modules are commonly delivered in fully operating status
with battery switched on and completed registration in Sigfox Network. For saving battery energy reasons the long
transmitting period (e.g. 1 day) is pre-set in the factory.
4.3
Modules storage
As the modules are already registered in the Sigfox Network on delivery and the subscription period is already
passing, it is strongly recommended to store modules only as short time as necessary. If necessary, store the
modules in dry rooms or halls, in the temperature interval (0
÷
30)
◦
C. To prevent the unwanted discharging of
internal battery it is recommended to keep the long transmitting period configured until the module’s installation.
IMPORTANT WARNING
Sigfox Network services are charged on the base of prepaid subscription, when each
individual device can be operated only until the end of subscription period and then it is automatically deactivated.
Operation of the module is the most economical in case the module was put into operation immediately after delivery
and it is kept in operation for all the subscription period.
4.4
Safety precautions
Warning!
Mechanical and electrical installation of the WS868-PLE-I module can be provided only by a person
with necessary qualification in electrical engineering.
4.5
Environmental protection and recycling
The equipment contains non-rechargeable lithium battery. It is necessary to remove battery before module disposal
and dispose battery separately in compliance with the dangerous waste disposal rules. Damaged, destroyed or
