DANGER
Hazardous voltages are used in the operation
of this equipment and could cause severe personal
injury or loss of life.
The following precautions should be observed to
reduce the risk of injury or death.
HAZARDOUS VOLTAGES
Only qualified technicians familiar with this equipment and the
information supplied with it should be permitted to install and
operate this equipment.
Installation of electrical equipment must be done in
accordance with National Electrical Code and any other state
or local codes. Proper grounding and conductor sizing must
be installed for safe operation.
During operation, keep all covers in place and cabinet
doors shut.
When performing visual inspections and maintenance, if
possible, be sure the MBS is turned off and the incoming

SKRU Wiring
If the Wall Mount MBS is equipped with a SKRU (Solenoid Key Release Unit) it comes with the SKRU factory-wired to the
MBS Terminal Strip TB-1. TB-1 is mounted on the lower left side of the MBS.
Complete wiring the MBS TB-1 SKRU to the UPS dry contacts TB before energizing the MBS or UPS. The SKRU is pow-
ered from the load side of the MBS output breaker.
Connect one end of the user-supplied 16-18 Gage twisted pair wiring to MBS TB-1 terminals 1 and 2. Connect the other
end to the UPS “Bypass Enable” dry contact TB terminals. See the gure below.

Appendix A - Lock-Out/Tag-Out Hasp Installation
The Toshiba wall-mounted MBS ships with a LOTO (Lock-Out/Tag-Out) hasp to be installed by the User in those applica-
tions requiring that capability.
Installation equipment required:
#2 Phillips Screwdriver
1. Twist the inner tongue and outer loop sections of the hasp in opposite directions, until the 0.5 mm join separates.
2. use the factory supplied hardware to mount the outer loop of the hasp on the MBS door. The two mounting holed for
the screws is located just aoe the door latch.
3. Use the factory supplied hardware to mount the inner tongue of the hasp on the inner edge of the door frame. The
mounting holes are located just above the goor latch.
4. After mounting both parts of the LOTO hasp, close th door carefully and verify the hasp loop slips over the hasp toun-
guer without interference.
5. This completed the installation of the LOTO hasp.
