3 .3 Preparation a) Remove any temporary protection or packing materials. b) The enclosure can be mounted on any suitable structure using the enclosure’s integral mounting facilities. c) The fixing bolts must be suitable for the mounting surface and the environmental conditions. -
Page 11: Initial Electrical Installation
INITIAL ELECTRICAL INSTALLATION WARNING ! Before starting any electrical installation work, ensure that the incoming trunk connection is isolated from any source of power. CAUTION! The temperature inside the enclosure could rise to 75°C.Ensure that all cables and cable glands fitted are rated to withstand these temperatures. 4 .1 Preparation Loosen the captive screws of the enclosure lid and then remove it to obtain access... -
Page 12: Cable Shield Ground
Note: It is important to prevent this connection from loosening and also to protect it from corrosion. Where the trunk and spur cables are protected by steel wire armour, this should be treated as part of the “protective” ground. Normal practice is to bond the armour to the plant structure at both ends of each cable. -
Page 13: Trunk Shield Grounded At Host; Spur Cable Shields Grounded At Barrier
IMPORTANT NOTE 937x-FB2 enclosures are factory-supplied with Option 1 grounding. If power is applied locally, for example during commissioning, when the trunk cable shield is NOT providing a ground connection, the spur cable shields must (temporarily) be grounded according to Option 2. When the trunk cable shield ground has been fully instated (or restored), the grounding method should be returned to Option 1. - Page 14 F93-XE Grounding Fieldbus link terminator terminals Trunk (+) Trunk (-) terminals terminals Trunk screen Local terminals ground connection Image to be updated Figure 4 .3 – Trunk Terminal Area connector details Trunk cables pass through the enclosure wall via cable glands into the Trunk Terminal Area.

Page 15: Trunk Wiring
4 .3 .2 Trunk wiring Connect the trunk cable(s) in the following way. • Remove the cover that protects the Trunk Terminal Area by applying gentle pressure to the textured finger grips on each side of it: this releases the catches from the recesses in the carrier housing, so that the cover may be lifted away to reveal the trunk terminals. -
Page 16: Trunk Surge Module 9376-Sp
4 .5 Trunk Surge protection module 9376-SP The 9376-SP Trunk Surge protection module can be fitted to the TTA to prevent damage to the equipment from voltage and current surges that could occur on the trunk wiring. The 9376-SP is a four pin module that plugs into the upper end face of the Trunk Terminator Assembly. -
Page 17: Blanking Plugs
4 .7 Blanking Plugs . Blanking plugs of factory-supplied Fieldbus Barriers are lightly tightened for ease of removal. Any blanking plugs that are not removed from the fieldbus barrier must be tightened to the required torque to meet the IP rating. Two types of blanking plug are supplied with the Fieldbus Barrier as shown in figures 4.8 and 4.9 below and should be tightened to a torque rating as shown in the table below. -
Page 18: Maintenance
5 MAINTENANCE When the enclosure is installed in a hazardous area it is important for personnel to understand what activities are permissible when fieldbus power is present and what are not. WARNING ! Read and understand what work is permitted inside the enclosure. Failure to comply with these instructions can endanger the lives or health of personnel and risk damage to the plant and the environment. -
