• For mains power connection, use the mains connector terminal either through
a permanent wiring or a flexible mains cable to an earthed mains outlet.
Always use cable ties to fix the mains cable at the dedicated fixing point
provided near the mains terminal connector.
- When installing permanent, fixed wiring, insert an easily accessible,
dedicated bipolar circuit breaker in the power distribution network.
- Never attempt to solder mains connection wires at the ends where they will
be wired to the terminal connectors.
• Avoid loops of wire inside the control panel cabinet and route cables so that
they do not lie on top or underneath of the printed circuit board. The use of
cable ties is recommended and improves neatness of the wiring within the
box.
• The battery used with this unit, must be made of materials of suitable
flammability class (HB or better).
• Any circuit connected either directly to the onboard relay contacts or to the
external relay contacts through the onboard electronic output must be rated
as a SELV (safety extra-low voltage) operating circuit.
- A mains switching relay must not be fitted inside the control panel cabinet.
- Always place a suppression diode (e.g. a 1N4001) across the relay coil.
- Use only relays with good insulation between the contacts and the coil.
- Maximum cable length for open collector output connection may not exceed
30 m. For longer distances, use relay output expansion (for example, ATS624
four-relay expander).
• The minimum clearance between equipment closures is 50 mm (between
equipment vents).
• Only use these units in a clean environment and not in humid air.
Environmental requirements are given in "Specifications" on page 35.
• For the panel terminal connections, the recommended torque is 0,3 to
0,4 N·m. This torque setting is independent from the AWG (thickness) of the
wires used. A value of 0,4 N·m is also the maximum allowed torque for this
connector.
