5.2 Protection Against Moisture Damage

It is important to take proper precautions during installation to ensure

that moisture will not come in contact with the electrical connections or

components of the system. The integrity of the system regarding

moisture protection must be maintained for proper operation and is

the responsibility of the installer.

If conduit is used, drains must be installed at water collection points to

automatically drain accumulated moisture. Conduit breathers should

be installed at upper locations to provide ventilation and allow water

vapour to escape. At least one breather should be used with each

drain.

Conduit raceways should be inclined so that water will flow to low

points for drainage and will not collect inside enclosures or on conduit

seals. If this is not possible, install conduit drains above the seals to

prevent the collection of water or install a drain loop below the

detector with a conduit drain at the lowest point of the loop.

Conduit seals may be required for compliance with explosion-proof

installation requirements. Units with M25 thread must use an IP66

washer to prevent water ingress.

5.3 Wiring Procedure

5.3.1 Wire Size and Type

The X33AF PL can only be used with the AutroSafe IFG system, and

must be connected to the BSD-340 PowerLoop driver.

The system should be wired using a "14 to 24 gauge" (2.0 - 0.2 mm

)

cable. The wire size selected should be based on the number of

detectors connected, and the cable length. The PowerLoop calculator

of the AutroSafe IFG configuration tool must be used to determine the

cable dimension.

NOTE: Refer to the “Power Consumption” in the “Specifications”

section of this manual.

The use of shielded cable is required to protect against interference

caused by EMI and RFI. When using cables with shields, terminate

the shields as shown in figure 4. Consult the factory if not using

shielded cable.

In applications where the wiring cable is installed in conduit, the

conduit should not be used for wiring to other electrical equipment.

CAUTION: qualified personnel should perform Installation of the

detector and wiring only.
