Mains Powered Systems
Previously installation requirements for 12V battery systems with solar or wind turbine charging
systems have been reviewed. An alternative system utilises local mains power to maintain battery
charge.
Two arrangements have been provided within the lubricators; Section 8.16.2 details the type used
prior to April 2011 and Section 8.16.1 after that time.
Cable routing and connection should be undertaken by trained and authorised personnel only.
Using the following procedure:
A suitable cable should be routed from the local trackside power source to the cabinet via
suitable armoured cable and routed into the cabinet through a suitable waterproof gland. The
cabinet can be drilled towards the base to suit the gland; care should be taken to avoid
damage to any internal cabinet components.
The cable incoming cable should be armoured and suitably routed and protected to avoid a
hazard.
Cable rating should be 220/110 Volt at 6 Amps minimum.
Connection should be made on the two pole MCBs to the left of the main Control Box. All
other power wiring will have been completed during product assembly.
Connection should only be undertaken with the lubricator installer present.
8.16.1
Lubricators supplied after April 2011 will have an auto voltage sensing industrial battery
charger
The charger has LEDs to indicate operation:
Green LED indicates mains power from the MCB output
Yellow LED:
o
Flashing indicates charging
o
Continuous indicates battery fully charged
Do not remove the MCB cover unless fully trained and certified electrician.
Wiring the MCB’s to the electrical supply must be undertaken by a qualified electrician.
The unit is supplied pre-wired to the MCB.
Incoming voltage is auto-sensed in the ranges:
90-265 VAC, frequency 45 – 65 Hz
90 – 350 VDC
Connect the ring terminals to the battery
terminal;
Cable with RED sleeve to positive battery
terminal. [Note: cable insulation is
smooth].
Cable with no sleeve to negative battery
terminal. [Note: cable insulation has 3
longitudinal ribs].
