SPM tie cabinets provide the UPS connection terminals for the shared load bus. These cabinets
also enable the make-before-break transfer of the load to the system bypass. This can be used
for service or test purposes.
The available SPM modules have the following maximum power ratings:
Type UPS rating Bypass rating System voltage
SPM-30-2 1-2 pcs x 30 kVA 60 kVA 400/230 V, 50 or 60 Hz
SPM-60-2 1-2 pcs x 60 kVA 120 kVA 400/230 V, 50 or 60 Hz
SPM-30-4 1-4 pcs x 30 kVA 120 kVA 400/230 V, 50 or 60 Hz
SPM-40-4 1-4 pcs x 40 kVA 160 kVA 400/230 V, 50 or 60 Hz
Input terminals have a five-wire connection (L1, L2, L3, N, and PE). Power cables with copper
conductors should be used to fit the terminals. The wiring shall be done according to the wiring
diagram. The terminals and cable routing is shown it the figure below.
Auxiliary contact information of the system bypass switch enables a safe transfer of the load.
Pay attention that the signal cable of the bypass switch aux. contact is wired correctly to the
UPS modules: the polarity of the signal must be the same for all parallel connected UPS
modules because the signal sensing is done against the ground.
Notice!
UPS modules should get a minimum of 10 ms leading closed-contact signal when the system
bypass switch is turned from UPS to BYPASS position.
