VCR type fitting
a. Remove the plastic or metal bead protector cap from the fitting.
b. If a gasket is used, place the gasket into the female nut.
c. Assemble the components and tighten them to finger-tight.
d. While holding a back-up wrench stationary, tighten the female nut 1/8 turn past finger-tight on
316 stainless steel or nickel gaskets, or 1/4 turn past finger-tight on copper or aluminum gaskets.
KF flange
The KF mounting system requires O-rings and centering rings between mating flanges.
a. Tighten the clamp to compress the mating flanges together.
b. Seal the O-ring.
ConFlat flange
To minimize the possibility of leaks with ConFlat flanges, use high strength stainless steel bolts and
a new, clean OFHC copper gasket. Avoid scratching the seal surfaces. To avoid contamination,
install metal gaskets.
a. Finger tighten all bolts.
b. Use a wrench to continue tightening 1/8 turn at a time in crisscross order (1, 4, 2, 5, 3, 6) until
flange faces make contact.
c. Further tighten each bolt about 1/16 turn.
2.3.3 Assemble and connect the wiring
2.3.3.1 Connecting Cable
The cable is user-supplied. MKS does not supply the cable. Install externally shielded cable
and connect the shield at both ends. At the module end of the cable, connect the shield to
the outer shell of the subminiature D connector.
On both versions of the module, connect the 11.5 to 26.5 Vdc power supply to terminals 3 and 4.
• Terminal 4 (ground) is negative (–).
• Terminal 3 (input) is positive (+).
See Section 2.3.4 for grounding instructions.
Do not connect or disconnect any electrical connectors while power
is applied to the equipment (hot swapping). Doing so may cause
damage to the equipment or severe electrical shock to personnel.
