4. Ensure that the installation site is in accordance with 2 Site Selection 4 1 Inspection Before shipment the PS1 was rigorously tested and dispatched in perfect working order Due to the freight distances and handling involved the inverter should be inspected as follows before installing it or connecting power to it 1 Inspect packaging for signs of damage 2 Remove packaging from unit and examine the inverter case and ensure there are no obvious signs of damage 3 Remove the PS1 from the shipping pallet by removing the two 2 bolts underneath the pallet 4 Inspect the top of the pallet and the underneath of the PS1 and ensure there are no obvious signs of damage 5 With a suitable screwdriver unscrew the two front door retaining screws and open the door to view the various Printed Circuit Board Assemblies PCA interconnecting cables and connectors See 7 1 Inverter Internal View 6 Checkall cable connectors to ensure they are properly seated in their sockets Avoid pulling on the cables or straining their connections Note Three pin cable under Power PCA is not connected Visually check all connections to circuit breakers and contactors 8 If all connections are sound and there are no signs of damage to the inverter cabinet proceed with installation If there are problems please contact the inverter distributor Please retain the inverter packing material for use if the inverter needs to be shipped 4 2 Mounting
5. The PS1 can be shelf or wall mounted One half of the wall mounting bracket is pre assembled to the PS1 This may be removed if not required The mounting position must ensure an adequate airflow A minimum clearance of 150mm must be provided adjacent to the ventilation inlet and outlet areas see Appendix A 9 Mechanical Details for ventilation area details The shipping pallet must not be used for mounting the PS1 All wiring to the PS1 must pass through the inverter bottom Ensure the mounting position allows for all of the required cabling taking note of the minimum bend radius of heavy DC wiring The PS1 is heavy Ensure appropriate lifting techniques and mechanical lifting aids are used when moving and mounting the PS1 Four eye bolts provided can be screwed into the top of the PS1 cabinet for attaching a lifting harness Unscrew and remove the four M4 hex bolts and the fibre washers from the top of the cabinet and retain Screw the four eye bolts with the fibre washers into position The eye bolts should be removed and the hex bolts replaced when the mounting has been completed 4 2 1 Shelf Mounting For shelf mounting the inverter can simply sit on the shelf or can optionally be bolted to the shelf via M8 bolts up into the inverters rubber feet See A 9 Mechanical Details for feet locations It is recommended that the PS1 be bolted into position The shelf must allow for the wiring beneath the inverter O Selectronic Australia
6. 4 3 Additional Componentry If any additional components are to be installed into the PS1 cabinet they may be installed onto the raised DIN rail Take care to ensure that any disturbed internal wiring is re connected to the same location Special attention is drawn to the small EMI leads fitted into the top of the AC and DC circuit breakers and into the top of the neutral terminal DO NOT DRILL into the internal chassis of the PS1 The primary transformer is located directly behind the chassis The un used pressed inserts in the chassis may be used to mount additional components Use the shortest possible 6mm M4 Zinc Plated Steel screws Ensure that hazardous voltages cannot contact with the chassis or any other wiring Check the clearance of additional components to ensure the door will close correctly DO NOT utilise the chassis earth screw and stud points for any mounting or additional earth wiring 4 4 Wiring This section provides information regarding the wiring of the PS1 only Ensure all wiring is de energised when making connections to the PS1 Ensure other power sources cannot automatically start and energise wiring All wiring feeds up through the bottom of the PS1 A gland plate and cable gland nuts are provided for the installation of all cable Any unused cable cut outs should be fitted with gland plugs to keep out vermin Suitable grommet edging material should be fitted to protect the wiring from sharp edges See Appe
7. attaching a lifting harness 1 3 Installation The PS1 requires adequate ventilation away from hot equipment Do not obstruct the airflow through the ventilation holes in the PS1 case sides rear and door top Ensure when installed in an enclosed space that there is adequate ventilation The PS1 must be located in a dry place away from water electrolyte and corrosive aerosols The PS1 contains arcing contacts so must not be located where explosive gas mixtures could occur such as hydrogen from batteries or diesel fuel fumes The PS1 must never be installed above the battery bank 1 4 Maintenance Ensure that all energy sources are isolated before working on connected wiring The generator may start or power may be restored by the inverter at any time Never work on equipment or investigate a problem without following appropriate safety isolation procedures Procedures are defined in the PS1 Technical Manual 1 5 Inverter or Generator may Start Automatically The PS1 automatically starts and or restarts and may restore power or start the generator at any time If a fault or overload is detected the PS1 will shutdown and automatically attempt to restart at varying intervals of up to several hours 1 6 Battery Batteries are very dangerous Please read the safety information provided by the battery supplier Battery acid is dangerous Batteries can emit hydrogen gas which is explosive Batteries connected in series can produce ha
