8.2. Initial Charging of the Battery Cells
To charge the PSU1 battery, connect the mains charger and switch on the mains supply. The
charging LED [8] will begin to flash, indicating that “fast charging” is taking place. Once the fast
charge cycle has completed, the LED will stop flashing and be lit (ON) continuously to indicate
“trickle charging” is ongoing.
Note: When battery cells are inserted for the first time, they should be continuously
charged for 16 hours to ensure full capacity.
Note: The PSU1 can be used whilst charging the battery cells or directly from mains power
without any battery cells being installed. However the outputs may carry some charger
noise.
Note: If the PSU1 is powered by the mains charger with no batteries cells installed then the
charging LED may flash. This is normal and can be ignored.
Note: To prepare for long periods away from a charging source, battery cells may be pre-
charged and used to replace discharged cells in the field.
8.3. Location of the Equipment
8.3.1. Potentially Hazardous Locations
WARNING: The charger supplied with this equipment is powered by mains electricity. It
should not be used in wet or damp locations, where water may enter the unit and create a
safety hazard.
8.3.2. Orientation
The PSU1 can be orientated horizontally or vertically.
8.3.3. Temperature
To minimise temperature induced drift effects, position the PSU1:
• in a constant ambient temperature
• out of direct sunlight.
8.3.4. Proximity to Other Equipment
The PSU1 contains no high frequency electronics likely to cause emissions which could cause
interference with other equipment. The unit is unlikely to be affected by interference from other
equipment in the normal operating environment.
