Connect Electrical Power
Electrical power connections must be performed by a qualified electrician or electrical installer and must
meet local electrical codes.
1.
The location of power input to the Polycold Cryochiller is on the lower right corner of
the front of the unit. There is a 49.2mm (1.94 inch) clearance hole in the outer skin and
a 42.1mm (1.656 inch) mounting hole on the frame for mounting an appropriate sized
strain relief or conduit connector.
Strain Relief Example: “OZ-Gedney KC-125T Flexible Conduit Connector”
2.
Route the 4 conductor cable or individual wires through the connection, up the right front leg, above
the cable tray that is attached to the bottom of the shelf that separates the compressor area from
the valve area, and then up to the circuit breaker area.
3.
Confirm that the protective grommet or strain relief is in place in the opening below CB1.
4.
When using larger cables, the (3) screws that hold the front edge of the upper cable track may be
removed and the track lowered to provide greater access. When completed, replace the (3) screws.
5.
If the input power cable is too large to route through the cable tracks or existing cable is too short,
use Terminal Block Accessory and Wiring Kt, p/n 181500.
If using 4-conductor cable that is too stiff to bend in the cable tracks, remove the outer jacket from
the cable after it passes through the strain relief. Optionally, use Terminal Block Accessory and Wir-
ing Kt, p/n 181500.
