Initial charging of the battery cells
To charge the PSU1 battery, connect the mains charger and switch on the mains supply (if appropriate).
The charging LED (item 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, 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.
Location of the Equipment
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.
Orientation
The PSU1 can be orientated horizontally or vertically.
Temperature
To minimise temperature induced drift effects, position the PSU1:
In a constant ambient temperature
Out of direct sunlight
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.
Note: The PSU1 is inherently magnetic and should, therefore, be sited as far from any magnetometers as
possible.
