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.
assemblies may be required to meet UL and local electrical code standards.
