Installation considerations

Read all instructions before installing and powering the device and keep these instructions in a
n
safe place for future reference. See
wiring safety guidelines.
Note When installing in a C1D2 area, you must use C1D2 listed, IP66 rated conduit and conduit
fittings to maintain applicable safety ratings on the Connect Sensor.
USB (P2) (J1) and SIM (P6) connectors are intended for maintenance use within a Division 2
n
classified area. These connectors can only be used if the power is disconnected or the area is
known to be free of ignitable concentrations of flammable gases or vapors.
All external or field wiring must be in accordance with NFPA 70 Article 501.10(B).
Connect Sensor is intended for fixed installations only.
n
Push button switches are not for normal operational or maintenance use in hazardous
n
locations.
If the device shows any signs of damage or malfunction when connecting the battery, remove
n
the battery connection immediately and contact your supplier for repair or replacement.
Changes or modifications not expressly approved by the party responsible for compliance could
n
void the user's authority to operate the equipment. Use only the accessories and battery
provided by the manufacturer; connecting non-approved accessories and batteries may
damage the device.
Do not attempt to repair the product. Any attempt to service or repair the device by the user
n
will void the product warranty.
Connect Sensor must be maintained by Digi or a Digi qualified technician only. Always use the

designated battery, model number 76000912, from Digi. You must remove the unit from the
installation or unclassified hazard location before opening the enclosure due to the risk of
batteries falling into a protected area.

n
Allowable wire size for terminal blocks is 0.5-1.5mm
