Page 15: Parallel Operation
TPCMQ48 SERIES INSTALLATION & OPERATING MANUAL 13.0 PARALLEL OPERATION Parallel Connection - Two or more TPCMQ48 modules can be operated in parallel by 13.1 connecting their outputs in parallel and connecting their current sense terminals together. The TPCMQ48 19-inch rack power shelves permit conveniently operating two or three units in parallel in either redundant mode or non-redundant mode. -
Page 16: Module Installation
14.0 MODULE INSTALLATION TPCMQ48 Series modules are designed for mounting into the TPCMQ48 Series power shelves or similar OEM housing. Fixing in place is achieved by means of a jacking screw that is also used to push the module home into the mating connector. -

Page 21: Shelf Installation
To minimize obstruction to ventilation there should be a minimum of 3 inches (76mm) free space behind and in front of the power shelf when it is installed in the rack. UNIPOWER also recommends that any equipment mounted directly above the TPCMQ48 series power shelf should be shorter in overall depth so as to not obstruct any ventilation holes in the top surface. -
Page 22: Maintenance
INSTALLATION & OPERATING MANUAL 18.0 MAINTENANCE No routine maintenance is required on the TPCMQ48 series except for periodic cleaning of dust and dirt around the front ventilation grill. A small vacuum nozzle should be used for this purpose. 19.0 SETUP AND TESTING The TPCMQ48 can be initially tested mounted in a rack or on a test bench. - Page 23 TPCMQ48 SERIES INSTALLATION & OPERATING MANUAL Disconnect the wire from the Inhibit & Standby return. The Output Power Good LED should turn on. Check the voltage on the Output Power Good pin as described above. The voltage should be a logic LO, +0.5V or less. Check that the DC output with a digital voltmeter.
