WARNINGS - 
ELECTRICAL SHOCK HAZARD. REMOVE ALL POWER FROM BOTH THE 
CONTROLLER AND RELAY OUTPUTS BEFORE MAKING 
TERMINATIONS.

ALL RELAY OUTPUTS MUST USE A COMMON VOLTAGE I.E. 230Vac OR 
24Vac. DO NOT MIX VOLTAGES. THIS IS REQUIRED TO PREVENT THE 
POSSIBILITY OF FLASHOVER FROM 230Vac TO 24Vac. 

ALL RELAY OUTPUTS MUST USE A COMMON PHASE. DO NOT MIX 
PHASES. THIS IS REQUIRED TO PREVENT FLASHOVER BETWEEN 
DIFFERENT MAINS PHASES.

THIS PRODUCT CONTAINS A NICKEL CADMIUM BATTERY WHICH IS 
COMPLETELY SAFE WHILST IN NORMAL OPERATION. BATTERIES 
MUST BE DISPOSED OF IN AN AUTHORISED LANDFILL SITE.

Cautions

Do not apply any voltages until a qualified technician has checked the 
system and the commissioning procedures have been completed.

If any equipment covers have to be removed during the installation of 
this equipment, ensure that they are refitted after installation to 
comply with UL and CE safety requirements.

This is a mains operated device. Local wiring regulations and usual 
safety precautions must be observed. Note Earthing requirements. 

Do not switch on mains power until commissioning checks 1 to 8 have 
been carried out.

Observe wiring precautions - see Page 8.

Analogue clock: Do not attempt to turn 'hour' hand. Do not set the day 
and time anti-clockwise as damage will occur.

Do not short circuit sensor terminals for test purposes.

Observe maximum ambient temperatures.

Interference with parts under sealed covers renders the guarantee 
void.

Information is given for guidance only and TAC Satchwell does not
