Hardwiring Cautions
•Wiring must be done by a qualified electrician.
•When making wiring connections, observe the cable connection regulations appropriate to your area [e.g. National Electrical Code (NEC) in the U.S.] at all times. Be sure to install an easily accessible disconnect switch in your installation wiring so you may cut off the UPS’s AC input during fires and other emergencies. Ensure that cables are fitted with cable sleeves and are secured by connector clamps. Tighten connections with a torque of not less than
•Make sure that your equipment is properly grounded.
•Using cables of improper size may damage your equipment and cause fire hazards. Choose appropriate cabling and protection circuits to make wiring connections. Ground conductors must be the same size and type as the power conductors used.
•See the product case for input and output ratings and refer to National Electrical Code (NEC) guidelines for proper wire gauge and output protection circuit requirements.
Connecting Modules to Each Other and to Utility Power and Equipment
1Attach the PDU to the Power Module and Battery
Module.
Align and connect the PDU's power module input terminals with the terminals on the back of the Power Module. Secure the PDU to the Power Module with four screws A . Before proceeding further, ensure that the Bypass Switch is set to NORMAL. Remove the utility input terminal block cover B .
2Hardwire the PDU to a Utility Power Source.
Pass a
Cand connect it to the PDU's input terminals D . Replace the terminal block cover. Connect the other end of the cable to a utility power source.
3Connect the battery module to the power module.
Consult the owner’s manual that came with your battery module. Fully insert the connector on the end of the battery module’s cable E into the connector on the rear panel of the power module F . Small sparks may occur; this is nor- mal. NOTE: the power module does not contain internal batteries and will not start until a battery module is connected. The battery modules are fully charged prior to shipping. However, before expecting full backup capability (particularly if the battery module has been stored for an extended period) after the UPS system is connected to a utility power source, allow the battery module to recharge for 12 hours. Once the UPS system is in use, it will charge the batteries and maintain the charge level automatically. If needed, connect additional battery modules in a
