The INVERTER should be checked for shipping damage immediately upon receipt and all damage reported to the carrier. Internal damage must also be reported to Dependable power systems.
Units must be stored in an upright position and in a dry location (0 to 50 degrees C, at 0 to 95% humidity). The storage location must not be exposed to the outside elements. Due to the possibility of battery deterioration, the INVERTER should not be stored longer than 6 months.
Although the INVERTER is a large, ruggedly constructed unit, it must be handled with reasonable care to avoid damage. Severe bumps and jolts must be avoided. Only personnel experienced in the installation of equipment of this size and weight should be used. The unit's size and weight can be found on the Outline and Interconnect drawing.
No Assembly is required, with the exception of the very large systems. With the large units, two or more modules may have to be bolted together and interconnected. On these units, refer to the Outline and Interconnect drawing for details. To facilitate moving a unit equipped with fans, the entire top fan panel may be removed. However, great care must be taken to avoid damaging the fan assembly.
The unpacked unit may be moved on it's wheels, when provided, or by a forklift or pallet jack. Due to the weight of the unit, ramps or sloping floors should be avoided when using the wheels or pallet jack.
The balance points of the INVERTER are typically not centered. The heavy side of the unit is noted on the outside of the packing material.
As with all electrical wiring, long runs of the AC wires or the battery wires, if required, should be avoided to reduce noise pickup and line drops. If batteries are mounted outside the unit, long runs can reduce battery run time.
The INVERTER generates some heat (see Outline and Interconnect drawing for BTU's), and therefore, should be in a well ventilated area. The temperature range for the standard INVERTER is 0 to 40 degrees C.
The primary ventilation is through the top and bottom of the INVERTER. Restricting the air flow by placing objects near, on top of, or under the unit could reduce the operating life of the unit. The clearance above the unit should be no less than 12". Primary access is obtained by the front door(s). In cases where adequate clearance is not possible, a minimum of 4" to the rear of the unit must be maintained for proper air flow.
Refer to the Outline and Interconnect drawing for the required electrical connections and the current requirements. All connections to the INVERTER, including an adequate earth ground connection, are to conform to local codes. If there is a conflict between the local electrical code and wiring diagrams provided, contact the Dependable power systems service department.
Areas are provided in the floor and at the top rear of the unit for cable and/or conduit entry. Connections are made to terminal strips located inside the front door (panel). See Outline and Interconnect drawing for exact location.
