4 3 2.0 Installation istructions 2.1 Safety inforation Te RTS igital series soul only be installe by a traine electrician. Te I.E.E wiring regulations ust be observe. Te supply ust be isconnecte before wiring coences an a eans of isolation wit a separation of 3 in eac current pat ust be provie in te supply to te RTS unit. Tis prouct ust not be installe were it ay coe into irect contact wit liquis. Te RTS unit is suitable for fixe wiring applications only. Te RTS igital series ust not be use wit inustry stanar electroecanical bases wit eart strips as ouble insulation ay be prejuice. 2.2 Electrical interference Despite elaborate safety precautions, exceptionally strong electrical fiels ay interfere wit any icroprocessor controlle tieswitc. We terefore recoen tat you observe te following points before installation: Suppress interference cause by inuctive loas by eans of an RC filter an/or varistor (VDR) Do not install te unit in close proxiity to sources of interference, eg transforers, contactors, Pcs an TV sets If interference occurs, we recoen tat you carry out a RESET (see section 7.0) before putting te RTS unit back into operation 2.3 Wiring iagra Fig 1a RTS17 RTS Fig 1b RTS174 M Fig 1c RTS274 M L N 2.4 Installation Tree fixing oles B countersunk wit central knock out Lug D on cover Lug C on base Fig 2 Tree cable oles leaing to terinals 1, 2 an 3 (terinal cover reove) Fig 4a RTS17/RTS173 SL Loa V COM N L N Voltage between V an COM - any AC voltage up to 250V Base Loa SV COM L N LD1 LD2 Fixing screw A for terinal cover wic also retains te plug-in tieswitc assebly Transparent cover Base Terinal cover Fig 3 Base Cable oles leaing to terinals 1, 2, 3 & 4 (terinal cover reove) Fig 4b RTS174/RTS274 4 cable/conuit knock outs in terinal cover (2 at te botto, 1 at eac sie) Base
