2. WARNING 
 

IMPORTANT NOTE ON BATTERIES: 
 
DANGER: Batteries are electrically live at all times, take great care never to short circuit the battery 
terminals. 
 
WARNING: Batteries are often heavy, take great care when lifting and transporting batteries. For 
weights above 24kg, lifting aids should be used. 
 
WARNING: Do not attempt to remove the battery lid or tamper with the battery internal workings. 
Electrolyte is a highly corrosive substance and presents significant danger to yourself and to 
anything else it touches. In case of accidental skin or eye contact, flush the affected area with plenty 
of clean, fresh water and seek immediate medical attention. 
 
VRLA batteries are “low maintenance” requiring no electrolyte top-up or measurement of specific 
gravity. Always refer to the battery manufacturer’s data.  
 
WARNING: If required, clean the case of the battery with a cloth that has been soaked or 
dampened with distilled water. Do not use organic solvents (such as petrol, paint thinners, benzene 
or mineral spirits) and other materials can substantially weaken the case. 
 
WARNING: Avoid charging the batteries in float/standby applications outside of the range quoted 
by the battery manufacturer.  
 
WARNING: Do not incinerate batteries. If placed in a fire, the batteries may rupture, with the 
potential to release hazardous gases and electrolyte. VRLA batteries contain substances harmful to 
the environment. Exhausted batteries must be recycled. Return them to the battery manufacturer or 
take them to your Council tip for appropriate disposal.  
 
The volt-free contacts provided on the A1584 must not be used directly to switch any voltage which 
exceeds 60V a.c @ 0.5 Amps or 24VDC @ 1 Amp. 
 
This equipment requires a 230V a.c supply. All installation work should be carried out in 
accordance with the recommendation of BS5839 Part 1 and the current edition of the IEE 
regulations by suitably qualified and trained personnel.   
 
This power supply is suitable for indoor use only and must be installed in a dry and clean area. 
 
This power supply must be earthed. 
 
DO NOT REMOVE THE COVER OVER THE SWITCHMODE UNIT AS THIS WILL EXPOSE 
DANGEROUS VOLTAGES.
