Caution: water cooled power supplies are not water tight. Allowing water
penetration is a safety hazard and will damage the power supply.
Each master/slave module has a 1/4" NPT female inlet and outlet for water flow. External
plumbing interconnects power supply modules. A minimum of 2.50" is recommended behind
the enclosure for this hardware and user connections. For systems requiring more than one
power supply, plumbing connections must be paralleled; that is, water should not flow from one
power supply into another.
2.2 AC Input Connections
Caution: disconnect AC power from the mains before attempting any
installation procedure.
Caution: a safety ground wire must be connected to the unit as indicated by
the protective ground symbol at the rear of the power supply.
AC power is wired to the power supply by attaching three cables plus ground for 3-phase
installations and two cables and ground for single phase installations. The manufacture
recommends cables, as specified in Tables 2.1 or 2.2, be crimped to ring terminals and securely
fastened to the four studs at the rear of the power supply. After connections are made, screw the
four standoffs into the back panel and place the protective shield over the connections.
This power supply is designed to be permanently connected to the power source requiring a
readily accessible disconnect device incorporated into the fixed wiring.
2.3 DC Output Connections
Caution: disconnect AC power from the mains before attempting any
installation procedure.
