Specifications for Easy UPS 3M

In Easy UPS 3M systems E3MBP60K400H can be used as a single maintenance bypass panel or as a parallel maintenance bypass panel.

Overview of Easy UPS 3M System with Parallel Maintenance Bypass Panel

UIB Unit input switch
SSIB Static switch input switch
UOB Unit output switch
MBB Maintenance bypass switch in UPS
SIB System isolation switch
Ext. MBB External maintenance bypass switch
NOTE: In parallel systems with an external maintenance bypass switch (Ext. MBB), the maintenance bypass switches (MBB) in the UPSs must be padlocked in the open position.

Single Mains Systems

Dual Mains Systems

Recommended Cable Sizes for 400 V

DANGER
hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 240 mm².
Failure to follow these instructions will result in death or serious injury.

Cable sizes in this manual are based on table B.52.5 of IEC 60364-5-52 with the following assertions:

  • 90 °C conductors

  • An ambient temperature of 30 °C

  • Use of copper conductors

  • Installation method C

PE size is based on table 54.2 of IEC 60364-4-54.

If the ambient temperature is greater than 30 °C, larger conductors are to be used in accordance with the correction factors of the IEC.

NOTE: Refer to the UPS installation manual for UPS input cable sizes.
