Primary/Reserve Power Cabinet Hardware
The type of cabinet mounting can have an effect the power requirements. There are two types of
mounting for the CTX100 and CTX670 (listed below).
• Cabinet Wall Mounting – The lightweight and compact design of CTX100 and CTX670
enables easy wall mounting. Wall Mounting requires no special hardware.
• Cabinet Floor Mounting – Only the CTX670 can be floor mounted (requires the BFIF
hardware kit). If floor mounting three or more cabinets, AC and reserve power must be
connected to the BCCB conduit connection box option by a licensed electrician. If more than
two cabinets require reserve power batteries, the BBDB must be installed.
Underwriters’ Laboratory (UL) and local electrical codes require certain standards for connecting
commercial AC and reserve power to the Strata CTX system. Tables 2-63 and 2-66 describe which
assemblies may be required to meet UL and local electrical code standards.
The power distribution hardware for the CTX100 is shown in Table 2-65.
