Good Practice During the Installation
A separate mains supply and earth running directly from the consumer meter is essential.
Avoid routing the mains cable to the power supply close to other supplies especially those providing
intermittent current motors that are starting and stopping continually or high power heaters with
thermostatic control.
Terminate the Remote Vacuum Sensor Control supply in a sealed, fused, double pole switched outlet
fitted with a 13Amp (Type 1362) fuse or trip. A 3-pin ring main socket is not suitable in parlour
conditions. All mains cabling must be contained in a firmly secured durable conduit.
Variable Speed Inverter Drive: Siting
Fix the unit to a wall in a well ventilated area sufficiently high to avoid physical contact or damage,
leaving a gap of at least 250mm (10") between the top of the box and the ceiling.
Ensure that S-Y Flex is used between the drive output and motor.
Ensure that the S-Y Flex is correctly terminated using the screen clamp within the unit.
Position the power supply so that the output cables are as short as possible even if this means extending
the mains supply.
ATL Remote Vacuum Sensor Power Supply: Output Voltages
ATL remote vacuum sensor power supply outputs are factory set and should not be adjusted.
Remote Vacuum Sensor Power Supply
Input: 100 - 240vAC
Output: Nominal 12vDC
The Remote Vacuum Sensor 12vDC power supply has a thermal cutout and overload protection which
removes power from the output in the event of an overload.
Control Cables and Conduit
Cables must be kept as short as possible running directly from point to point. Cut out any excess cable
rather than leaving it coiled.
Wherever possible cables should be contained in a waterproof conduit using
the correct csa cable
specified in the diagrams.
Entries must be made into the bottom of control casings but never into the top. This will
invalidate the warranty.
Strip existing cables back to bright copper before connection.
Keep high voltage and heavy current carrying cables away from low voltage and data cables. Cross
o
only at 90 where necessary and do not enclose in conduit with other cables.
