The unit is intended for installation in a controlled environment, with a
maximum ambient temperature of 25°C.
(indoors, temperature controlled and free of conductive contaminants).
This UPS must be secured to the floor with the blanket provided.
This UPS is intended for use in Japan.
All models require an external disconnect/over-current protection device for AC
input and AC output. -For example, a UL listed branch circuit breaker can be
used to provide both functions (disconnect and over-current protection).
・
A readily accessible disconnect device shall be incorporated in the building
installation wiring.
・
When M-UPSXXXAD*S-# is not installed, a circuit breaker (UL-approved
back flow prevention circuit breaker) is not installed on the input side of the
UPS; a circuit breaker must be connected when the UPS is used. The rated
trip current of the circuit breaker (2-pole type) is shown in Table 1, Table 2,
and Table 3.
・
Field wiring must use UL- and CSA-rated closed-loop terminal connectors
that match the wire size and are fully insulated all the way to the terminals.
Connectors must be secured using a crimping tool specified by the connector
manufacturer. Closed-loop terminals are available as shown in Table 1,
Table 2, and Table 3 (manufactured by Japan Solderless Terminals). If these
terminals are not available, use similar terminals.
・
Use 75°C copper wire for conductors.
Wire sizes and tightening torques are shown in Table 1 , Table 2 and Table 3.
Figure 1 shows the circuit diagram.
The UPS must be installed with flexible conduit.
