Protective earth grounding
Protective earth grounding must be verified prior to plugging the
S.U.M. into any electrical outlet. Ensure the receptacle is properly earth
grounded.
Environmental conditions
• Operating: 17 to 27°C; 20 to 80% relative humidity, non-condensing
• Storage: –25 to 65°C
• Installation category II (over voltage) in accordance with IEC 664
• Altitude limit: 2,000 meters
• Pollution degree II
Electrical connections
Power should be supplied by a properly-sized non-GFCI circuit.
Ground faults occur when current is leaking somewhere, in effect,
electricity is escaping to the ground.
Electrocution can occur when
the human body serves as the path for the leakage to the
ground.
A Ground Fault Circuit Interrupter (GFCI) senses the current
flowing to the ground and switches off the power (trips the GFCI) in a
fraction of a second at currents well below those that are considered
dangerous. Due to the sensitivity of GFCIs to electrical leakage (a few
mA), it is recommended that the imPULSE Single-Use Mixer NOT be
plugged into a GFCI outlet.
Vessel jacket information
The imPULSE hardware unit with vessel jacket has been designed
to be operated with water/glycol as the heat transfer medium, with
temperatures not exceeding 50°C (122°F) under less than 150 psig (1
MPa) operating pressure. For the utmost safety it is recommended that
the S.U.M. be operated at 75 psig or less.
Note:
While the vessel jacket may be operated at 50°C, the imPULSE
BPC is limited to 40°C maximum. As a result, the jacket may only be
operated at 50°C until the BPC temperature reaches 40°C, after which
it must be lowered. The internal pressure of the imPULSE BPC should
not exceed 0.5 psi.
Note:
The vessel jacket is not required to be registered, inspected, and
stamped with the Code U symbol per section U-1(c)2(f) of the ASME
Boiler and Pressure Vessel Code and/or European Pressure Equipment
Directive (PED) 97/23/EC. Upon request, a Declaration of Conformity,
PED Sound Engineering Practices can be made available.
