1. Attach the half-rack instrument to the 937B Controller using the small splicing plate and the
four 10-32 screws provided. The splicing plate is used to connect the front panel of each
instrument together.
2. Secure this assembly to the rack using the ¼"screws provided. It may be necessary to
loosen the 10-32 screws securing the splicing plate to align the holes with the mounting
holes on the rack.
All items in the kit may not be needed, depending on the mounting configuration.
Contact an MKS Applications Engineer for solutions to other mounting configurations.
10.5 AC Power Cord
The Controller has a standard female IEC 60320 connector for connecting to a 100-240 VAC, 50/60 Hz
power source. Use only a harmonized, detachable cord set with conductors having a cross-sectional area
equal to or greater than 0.75 mm
2
. The power cord should be approved by a qualified agency such as UL,
VDE, Semko, or SEV.
Properly ground the controller and vacuum system.
The 937B Controller is grounded through the ground conductor of the power cord. If the protective ground
connection is lost, all accessible conductive parts may pose a risk of electrical shock. Plug the cord into a
properly grounded outlet only.
Do not exceed the manufacturer's specifications when applying voltage.
Electrical shock may result.
