General Information The Model 703-007 RTU (Remote Terminal Unit) Enclosure is designed to be a component in GAI-Tronics SmartSeries system. It mates with a SmartSeries handset or speaker amplifier to form a SmartSeries station. [. . . ] System layout and power cable length are very important when installing Page/Party equipment. Although it varies for different systems, the general guideline is that the total power cable length should not exceed one mile (5280 feet) for 120 V ac systems. The total cable length is the most important consideration while cable length between the stations is generally not a factor. Mounting The Model 703-007 RTU Enclosure is not supplied with conduit or cable openings. Drill or punch these openings using Figure 6 before mounting the enclosure. Whenever possible, do not enter an enclosure from the top: side or bottom entry helps to prevent moisture from dripping onto the terminals or PCBAs. Plain entry holes must maintain the following: · · · The plain hole shall be no larger than 0. 7 mm above the major diameter of the entry thread. The gland or stopping plug is secured internally by a locknut, such that the gland or stopping plug will be not dislodged by a 7 N-m impact. The enclosure will be maintained at IP 66 by a suitable sealing washer under the shoulder of the cable gland or conduit hub. The customer may drill plain entry holes in the enclosure providing they are in accordance with the relevant code of practice and comply with the details shown in Figure 6. When mixed entries are accommodated on a face they must be in the positions shown in this manual for the largest gland entry on that face. Entries into the enclosure must be via a suitable approved entry device. All unused entry holes must be fitted with a stopping plug with a certification equal to that of the enclosure's ATEX certification. The stopping plug shall be held in place by a locknut. f:\standard ioms - current release\42004 instr. manuals\42004-687l2b. doc 11/10 Model 703-007 SmartSeries RTU Enclosure Pub.
