Environmental Requirements
These loads are not intended for use outdoors where they would be exposed to
the elements. They should be used indoors in a clean, dry, dust and vibration-
free environment. The ambient temperature range is determined by the cool-
ant. For details of the temperature ranges refer to the specifications. It is
important that the room temperature remain within these limits for proper
operation of the unit, otherwise a derating of the load value will be necessary.
The Model 8655B/56B Moduload is to be installed and operated in a horizontal
position. The unit is shipped horizontal, and normally stands on its attached
base brackets.
For installation of the equipment, mounting angle brackets are attached to the
front and back edges of the enclosure. They may be removed by unscrewing the
four 8-32 Phillips Truss head screws holding each bracket. These brackets have
two elongated holes each on 17 inch by 49-1/2 inch (432 x 1257 mm) centers to
accommodate four 1/4 inch screws that may used for mounting the unit.
The load can be operated anywhere that adequate AC line power, and ventila-
tion are available. Ensure the ambient temperatures do not exceed those
given in the specifications.
Note: Since 50 kW is equivalent to 170,650 BTU/h, a sufficient
quantity of air must be provided. Allow room for unobstructed air
intake over the whole surface of the grilles, on both sides of the equip-
ment, and a clearance of at least three feet over the top of the unit.
Interlock Connections
A terminal strip provides connection to the transmitter’s internal safety inter-
lock circuitry. An active interlock state occurs as a result of either high coolant
temperature or no coolant flow. It will also be active for almost two seconds
after power up.
Interlock connections are made to the terminal strip on the front of the unit.
Note: Use number 22 AWG (or heavier) wire for interlock connections.
Connect the interlock wires to the interlock terminal strip as required for the
transmitter in use.
WARNING
Do not attempt to handle or move this unit alone. More than one person is
needed to move this unit to avoid possible injury.
