FlexPower Vantage Standard Power System - Installation Manual 7
Tamper Switch Wiring
Typical Installation and Wire Routing
Vantage power supply systems with an enclosure may in-
clude a normally closed tamper switch for monitoring by
the host panel. The tamper switch can either be brought
into a dedicated input in the panel (see the panel's instruc-
tions), or the tamper switch may be series connected into
the System Fault relay in the FPV supply (see Figure 1).
Any UL1076 installation must use the tamper switch to
indicate the opening or removal of the front door of the
enclosure.
Figure 2 shows a typical installation.
Actual configuration and wire routing will vary based on
the components installed in your system.
The following guidelines should be followed for installation:
• Class 2 Power limited wiring must be separated from
non-power limited wiring by a minimum of 1/4 inch
and must use separate knockouts.
• Any wiring passing through knockouts in the bottom or
top surfaces of the enclosure must be enclosed in rigid
or flexible metal conduit.
• Canadian Installations - For permanently connected
equipment, a readily accessible disconnect device shall
be incorporated external to the equipment. Output cir-
cuits not connected to removable terminal strips shall
also utilize a readily accessible disconnect device.
