3. WIRING AND POWERING UP
3.1
Grounding
–
Lightning Protection
The control panel must be earth grounded for lighting protection to work effectively, and in order to
prevent RFI and EMI interfaces. Attach the ground connection to a verified cold-water pipe using a
minimum 16 AWG (or larger) wire, or according to the country grounding standard. Run the ground
wire via the shortest possible route.
System grounding is compulsory. For trouble free system, use a good ground.
Connect the Grounding wire to main board and to the metal box.
Note: Connect the Ground wire to the terminal marked
. This is not a Minus (-V).
Beware of static discharge; before handling the main board touch a grounded metal.
Before grounding the system, verify that the ground is properly connected and does not transfer high
voltages. If ground is not available, run a ground wire and connect to a cold water pipe as close as
possible to earth.
3.2
Back Up Battery
Verify that Battery is in the correct polarity! Prevent long AC failures!
Red wire is the positive pole (+). Black wire is the negative pole (-).
Verify that your step-down transformer supplies 16V AC, higher voltage will cause over-heating.
The battery provides power back up in case of AC power failure.
Connect back-up battery to ensure proper operation of the system.
Recommended battery: 6.0 to 7.2 Amperes per Hour (AH), 12V SLA (Sealed Lead Acid) type.
A 7.2 AH battery provides back up power to control panel and a single keypad for approximately
10 hours.
Panel accommodates a battery of up to 12V - 7.2 AH (max.).
A 2.5A electronic fuse protects the battery.
Prevent full battery discharge; in case of long main AC fail disconnect the battery. Instruct
user not to disconnect AC when living premises for long journeys or other occasions.
