Remote Emergency Power Off (REPO)
If required, the output power can be disabled in an
emergency by closing a switch connected to the REPO.
Two connection methods are available:
• Internally powered for use with non-powered
switch circuits.
• Externally powered for use with +24Vdc powered
switch circuits.
• The REPO circuit is considered a
Class 2 (UL and CSA standards)
and SELV (IEC standard) circuit.
• Both Class 2 and SELV circuits
must be isolated from all primary
circuitry. Do not connect any circuit
to the REPO terminal block unless
it can be confirmed that the circuit
is SELV or Class 2. If there is a
question, use a contact closure
switch.
• Use one of the following cable types to
connect the UPS to the REPO switch:
CL2: Class 2 cable for general use.
CL2P: Plenum cable for use in ducts,
plenums, and other spaces used for
environmental air.
CL2R: Riser cable for use in a vertical
run in a shaft of from floor to floor.
CLEX: Limited use cable for use in
dwellings and for use in raceways.
• For installation in Canada: Use only
CSA Certified, type ELC (extra-low
voltage control cable).
• Wiring by a qualified electrician is
required.
