General rules for installation:

Important note: These connection boxes are intended to monitor or control ambient temperatures in gas or dust hazardous areas. PPS enclosure and stainless-steel accessories allow their use in industrial or marine environments, including in cold polar areas

For gas hazardous areas, this equipment is approved as “Ex-eb” and is suitable for use in zone 1 and zone 2, gas group IIC (Hydrogen/Acetylene, the highest protection group), with a temperature classification T5.

For dust hazardous areas, this equipment is approved as “Ex-tb”, suitable for use in, zone 21 and zone 22, the dust group is IIIC (electric conductive dust, the highest protection group), with ambient temperature limits on its body from -60°C to +80°C.

Main use: These enclosures have been engineered for use with flat self-temperature controlled heating cables and mounted on pipes or vertical wall or poles.

Approvals: These enclosures are certified: ATEX: TÜV 22 ATEX 8894 X; IECEx: IECEx TUR 22. 0059 X; CCCEx: pending

Housing: UV-resistant PPS, diameter 150mm, maximum depth 200mm. The box also includes a long PPS foot allowing offset mounting on pipes. Waterproof class IP65. Shock resistance greater than IK10.

Lid: Unscrews in ¼ turn, with lock. The lid also includes a stainless-steel anti-fall chain and two holes for seals. The lid automatically locks in the closed position. It can be unlocked simply with a small flat screwdriver.

Identification: Riveted anodized aluminum plate, fixed to the rear wall.

Cable glands: A M20 cable gland and a M25 cable gland are incorporated as standard on the right side. Up to 2 tapped holes for 16, 20 or 25mm cable glands are possible on the opposite side. The leg includes a special cable gland that can accommodate up to two flat heating cables and a diastat capillary with a 6mm diameter wall penetration fitting.
The leg gasket is tightened by four M6 stainless steel locking screws.

Mounting options (both options use the same heating cable gaskets and internal fittings):

Y92 Series: Pipe-mounted, via a 127mm foot, with a hose clamp (10 × 35mm opening). Maximum temperature supported by the pipe-mounted foot: 220°C

Y93 Series: Wall-mounted, on a pole or vertical surface, via a short 100mm foot and stainless steel mounting plate

Optional accessories:
- A 35mm DIN rail, useful width 70mm can be mounted on the two holes with 96.5mm distance.
- A stainless steel plate for mounting of 4mm² and 6mm² ATEX connection blocks made by JPCI.
- A stainless steel plate for mounting KA series explosion-proof thermostats is automatically included when this
enclosure is ordered together with a thermostat. See references on KA thermostats pages.
- Cable glands can be fitted with special bolts for use with electrical cable protection tubes with Atex approvals.
