Power requirements
If possible, all components should be connected to the same line voltage supply
circuit. This avoids voltage differences between components. All circuits
must
have
a common ground.
Grounding
The three-conductor power outlet provided for the MSD must conform to the
International Electrotechnical Commission (IEC) requirement for grounding of
electrical instruments. This requirement provides that the ground contact be
connected to a suitable earth ground.
The power cord connector (plug) provided will be compatible with the line voltage
outlets in the country of destination unless otherwise specified in the purchase
order.
Power Specifications (MSD only)
120 V ac or 220–240 V ac (+5%, -10%), 47.5–63 Hz, single-phase, nominal
900 VA maximum
400VA maximum for foreline pump only
IEC Transient Overvoltage Category (Overvoltage Category) II
IEC Pollution Degree 2
Gases
GC carrier gas
A regulated supply of high-purity (99.999%) carrier gas (typically helium) is
required. A two-stage regulator should be used at the gas supply to eliminate
pressure surges. If other gases are required for GC operation, refer to the GC
hardware manual. Installation, check-out, and verification of the system will
only
be performed using helium as carrier gas. The customer is responsible for changing
to any other carrier gas after installation.
A three-stage trap is supplied for installation between the carrier gas supply and the
GC.
