Page 8: Safety Considerations
Damage to the equipment and potentially hazardous conditions for personnel may occur if a CAUTION statement is ignored. Each Avtron unit is safety checked for opens and shorts, and the insulation is high potential tested to ensure safe operation. All fuses, safety interlocks and related safety equipment have been tested as part of the testing procedure of each unit. - Page 9 Avtron Resistive Load Bank - Part Number LPV600 994210 Safety Considerations Replace any burned out bulbs on the Control Panel. Each lamp is an indication that a system is active or has failed and is important to the operation of the Load Bank and safety of the operator.

Page 12: Description
SECTION II DESCRIPTION The Model LPV600 Load Bank is a portable, primarily indoor, self-contained unit for electrically loading and testing generators. The Load Bank is rated at 600 kW at 600 VDC and 300 kW at 300 VDC. The available load steps are 240 kW, 120 kW, 120 kW, 60 kW, 20 kW, 20 kW, l0 kW, 5 kW, 2 kW, 2 kW, and 1 kW at 600 VDC. - Page 13 Avtron Resistive Load Bank - Part Number LPV600 994210 Description overload relay, fuses and customer connection load bus. The cooling air is drawn in from the bottom and lower sections of side access panels, forced across the resistor elements and exhausted out the top of the unit.

Avtron Resistive Load Bank - Part Number LPV600 994210 Installation SECTION III INSTALLATION BEFORE INSTALLATION Inspect the Load Bank for obvious damage such as broken wires, broken or dented panels, cracked ceramic insulators, or any other component breakage that may have occurred in shipment. - Page 15 Load Banks mounted into a channel, trough, hollow, well, or pit, or exhausting into a full wall or corner, require special considerations even if above conditions are met. In these cases, provide a detailed sketch of site layout for Avtron to inspect and comment.
- Page 16 Avtron Resistive Load Bank - Part Number LPV600 994210 Installation POWER REQUIREMENTS The Load Bank requires a 120V, single phase, 60 Hz, 20 amp source of power for operation of the control circuit. An integral 480/120V control power transformer is provided for powering the control circuit.
- Page 17 Avtron Resistive Load Bank - Part Number LPV600 994210 Installation GROUNDING A permanent ground should be connected to the Load Bank enclosure either by a grounded conduit or with a separate ground wire to prevent a potential above ground on the enclosure. No internal ground connections are made to any terminal on the Load Bank.
