Assembly, dimensions

The safety interlock switch must not be used as a mechanical stop or as a centering tool for the moving guard. An additional limit stop on the fixed part must be anticipated. After adjustment, make it is impossible to dismantle the support key. Only keys XCSZ 01/02/03/05 must be used.

1. Earthing the box.
2. Fitted cable gland for «ISO M20x1.5» version.
   • Unprovided cable gland for «1/2 NPT» version.

Field wiring cable gland for metric entry shall be provided of a seal or gasket, rated IP66/IP67 and Type 1, 2, 3, 4, 4X, and 12 as applicable, suitable for the type of protection marked on the equipment. Use suitable cables and cable glands to a minimum temperature of 65 °C for an ambient temperature of 60 °C.

Electrical setup

Check that starting cannot be carried out when the protector is opened. Remove the cover and connect the contact in accordance with the diagram corresponding to the estimated risk. Replace the cover carefully with all gaskets in place. To obtain better immunity to interference and reduce the size of secondary currents from other circuits, we strongly recommend that you wire each intrinsically safe (IS) channel with 2 conductors contained in the same sheath. “Control” and “power” cable networks must be kept separate.

Operation

These devices can achieve up to category 4 PL=e or SIL 3 (if combined with an appropriate Control Safety Unit PL=e / SIL 3).

• Before startup, check that the product has not been damaged (do not use a device if it is damaged).
• Check that the product’s labeling specifications are compatible with the conditions permitted for the Ex zone at the site where it is being used: (Group II: Surface industries – Category 2: high protection level – G: Gas – D: Dust – IPxx: degree of protection (protection against solids and liquids) – T 85 C° / 185 F° : max. surface temperature).
• Store products in their original packaging, in a dry place, T : -40…+70 C° / -40…+158 F°.
• commissioning:
• Connecting the contacts (see specifications). Tightening torque for the screw clamps: min. 0.8 N.m – max 1.2 N.m
• Clamp the cable (Ø6…12 mm) in the fitted cable seal ISO M20x1.5.
• Fitting and adjusting the product: see page 2/2.
• Before closing the cover, ensure that the gasket is in good condition and correctly positioned.
• Ensure that the 2 screws in the cover are tight. Tightening torque: 1.5 N.m

Assembly precautions

IF the electrical connection is made in the risk zone, ensure that the junction box is certified as compliant with this zone. The device must be assembled in accordance with the operating instructions (position, clearances, etc.) Serial or parallel wiring of safety interlock switches or wiring together with magnetic switches is strictly prohibited on the same intrinsically safe loop. As the intrinsically safe relay is the interface from which the peak limiting protection conditions are established, it must be installed outside the danger zone or in an Ex enclosure with appropriate protection. The total resistance of the outward and return conductors in the intrinsically safe loop must be less than 50Ω.
