Care and Safety
Batteries
Any external lead acid batteries (i.e. external to any data logger) should have an in-line
3A fuse to protect the GP1 network extension cables.
Only use one external battery. The GSM modem, including any GP1 network should
never have more than one battery connected (one may be present in the GSM modem
box!)
Only use our approved lead acid batteries (which minimise outgassing) in the GSM
box. Other lead acid batteries should be mounted together with the regulator/charger
in a separate well-ventilated enclosure provided by the user.
Do not charge any external battery (including one in the GSM modem box) via any of
the M8 to M8 5-core extension cables (to protect them from any accidental short circuit
currents).
Do not power the GSM modem via any M8 to M8 5-core extension cable (The modem
may use 2-3A on start up).
Solar power
To prevent shocks
cover the solar panel
before connecting or disconnecting wiring.
The solar regulator/charger must be installed vertically for correct operation.
The solar panel wires MUST have the correct polarity (brown + and blue -)
Desiccant
A desiccant bag is provided with the GSM box to buffer humidity changes inside the
box and prevent condensation. Replace or regenerate this annually.
