5.4 FUSE REPLACEMENT
Ensure the power supply is completely isolated before proceeding.
Fuses should always be replaced with the same type and rating.
Replacement of the fuse should only be carried out when the cause of failure has been rectified.
Substitution of larger ratings or alternative forms of conductor may result in damage to the instru-
ment.
Battery Fuse: A 20 mm 2A antisurge fuse protects the batteries. The fuseholder is located on the
battery wiring harness.
Main Power Fuse: A 20 mm 3A 230V slow blow, glass fuse soldered into the main power supply
card. This fuse will only be damaged when a serious fault occurs. Failure should only be investi-
gated by a service engineer.
NOTE: Unit should be returned to Fireye for determination of failure. Field replacement not recom-
mended.
Before attempting to change fuses the instrument must be disconnected from the main power
supply.

BATTERY CHARGING/REPLACEMENT
The Firetron 1000 can operate for up to 8 hours continuously depending upon which facilities are
being used. After this time period has elapsed the batteries have to be re-charged. This is undertaken
by connecting the main power supply cable to the side mounted socket (See Description of instru-
ment). The Firetron 1000 is fitted with an on-board battery charger. The unit will recharge the batter-
ies overnight.
If the Firetron 1000 is not used for extended periods i.e. 1-2 months, it is advisable to re-
charge the batteries at this interval or alternatively disconnect the terminal connectors to
the battery.
Battery Replacement
If the batteries need replacement, follow the procedure given below:
1.
Ensure the Power Supply is completely isolated.
2.
Remove side panel by release of retaining screws.
3.
Disconnect the two spade terminal connectors per battery i.e. red and black per battery.
4.
