Remote EPO Switch Dimensions3.2.2 UPS System Power Wiring PreparationRead and understand the following notes while planning and performing the installation:WARNINGAs a result of the connected loads high leakage current is possible. Connection to earth ground isrequired for safety and proper product operation. Do not check UPS operation by any action thatincludes removal of the earth (ground) connection with loads attached.l Refer to national and local electrical codes for acceptable external wiring practices.l To allow for future kVA upgrades, consider installing a derated UPS using wiring and external overcurrentprotection breakers sized for a fully rated UPS.l For external wiring, use 90°C copper wire. Wire sizes listed in Table 3-4 are for copper wiring only. If wire isrun in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may benecessary. Wire sizes are based on using the specified breakers.l Wire ampacities are chosen from Table 310-16 of the National Electrical Code® (NEC®). Specification is forcopper wire with a 90°C rating.l Material and labor for external wiring requirements are to be supplied by designated personnel.l If installing an external maintenance bypass, a minimum of two separate feeds with upstream feederbreakers, or a single feed with two upstream feeder breakers, must be provided: one for the UPS and onefor the external maintenance bypass input. DO NOT use a single feed or a single feeder breaker to supplyboth the UPS and the external maintenance bypass.l The bypass feed into this equipment uses four wires. The rectifier feed into this equipment uses four wires.The phases must be symmetrical about ground (from a Wye source) for proper equipment operation.115.8[4.56]114.3[4.50]0.87[0.22] 88.9[3.50]1.57[0.40]95.3[3.57]Front View1/2" Knockout Pattern(Typical 5 SidesNeeded toremove key(Square)Dimensions are in millimeters [inches]
