6.1.3 Connecting the battery and power supply
These safety precautions must be observed:
• Only insert the approved Grundfos battery pack (97631960).
• Never use this battery pack in other battery chargers.
• Do not dismantle or modify the battery.
• Do not heat or incinerate the battery.
• Do not pierce, crush or cause mechanical damage to the
battery.
• Do not short-circuit the battery.
• Do not allow the battery to get wet or be immersed in water.
• Do not strike or throw the battery.
• For long periods of storage, the temperature should be below
45 °C.
The CIM 250 is fitted with a lithium-ion battery. It is secured by a
velcro strap which absorbs vibrations and makes it easier to
replace the battery. Connect the battery to the CIM 250 as shown
in fig. 15.
Fig. 15 Connecting the battery
Switch on the power supply. The CIM 250 is powered either by
the CIU 250 or by the battery.
The LED1 flashes yellow (searching for GSM network). When the
connection to the GSM network has been established, the LED1
will pulsate yellow (GSM network active). See fig. 16.
The LED2 must be constantly green, indicating that the CIM 250
has been fitted correctly in the CIU 250.
6.1.4 Configuration
For software configuration of the CIU 250, which includes setting
of SMS functions and SCADA communication parameters, see
"CIM 25X SMS commands" (supplement to the installation and
operating instructions) on the CD-ROM supplied with the GSM
module.
Note
The slanted edge of the SIM card must point
downwards (away from the connector).
The connectors on the SIM card must face
inwards towards the CIM 250. See fig. 14.
