Refer to the battery manufacturer or supplier for advice on minimum ventilation levels.Do not wear a synthetic dust-coat or overalls. Synthetic fabrics can hold static electric charges that createsparks during discharge.Remove rings, wristwatch and other metal jewelry that might be exposed to battery terminals, beforeinstalling batteries.Batteries are powerful sources of energy and present a potential electrical shock and energy hazard. Theenergy hazard is always present, even if the batteries are not connected. Avoid short circuiting terminalsof opposite polarity.Always use insulated tools.Do not place tools, loose cables or metal objects (such as interconnecting bars) on top of batteries.Do not drop tools, loose cables or metal objects onto intercell connections or terminals of oppositepolarity.Only terminate cables and interconnecting bars after confirming that the termination will not create ashort circuit.Always tighten battery terminal bolts according to the battery manufacturer’s specification. Failing to doso can cause erratic battery performance, possible damage to the battery, and/or personal injury.There is a risk of electric shock or explosion if a battery is replaced by an incorrect type.Dispose of batteries according to the instructions on page 63.RectifiersOnly operate the rectifiers when the surrounding area is clean and dust free.To reduce the risk of electric shock and maintain optimum system cooling, always cover empty rectifierslots with blanking panels.To avoid electrical shock, do not place hands inside the rectifier magazine.Rectifier cases may exceed 100ºC (212ºF), especially after prolonged operation. Use suitable gloves whenremoving a rectifier from the magazine.Do not attempt to disassemble faulty rectifiers. Return them (in their original packaging) with acompleted Equipment Incident Report on page 99.Ensure that any upstream Residual Current Devices (RCDs) are appropriately rated for the rectifiers'maximum earth leakage current (see Specifications on page 69 for value).DC Distribution(s)The dc common bus of the dc power system can be connected to earth (ground). If this connection ismade all of the following conditions must be met:Your equipment and the dc power system must be located within the same premises.No switching or disconnecting devices are allowed in the conductor between the dc common lineand the point of connection to the earth electrode conductor.See Connecting the Output to Earth on page 19 for further information.For installations in the United States, Listed compression connectors must be used to terminate Listedfield-wired conductors where required. For all installations, use the appropriate connector for theconductor size as specified by the connector manufacturer. And use only the connector manufacturer'srecommended tooling or tooling approved for that connector.Follow all applicable local and national rules and regulations when making field connections.Tighten all electrical connections to the torques stated in this guide or on the manufacturer's label.
