1. Safety Instructions
The units of the series MCA deliver dangerously High Voltages! Ensure that
nothing, and nobody, will be endangered by this High Voltage before putting the
unit into operation!
Attention !
The full dielectric strength of the high voltage connectors is only achieved if
fully mated together.
Before Commissioning
Make sure that you have read and understood the operating instruction manual!
Ensure that you observe all the hints and warnings contained within it. In not following
the operating instructions, you contravene the safety regulations for operating units of
this type. FuG accepts no liability for consequences arising from the failure to follow
these safety instructions.
Mains voltage
Check whether the input voltage for your power supply, noted on the type label,
corresponds to your actual mains voltage.
Earth
The unit is provided with a safety earth (German safety class I). For protection against
electric shocks, the unit must be connected to the mains via a suitable 3 or 5-pole
cable with a non-fused earth conductor.
For electrical potential equalization to the load, and to the center of the AC-supply, the
earth stud must be used.
High leakage current!
Labeled by a sticker on the rear. At a high leakage current is an earth connection to
the Earth stud mandatory.
Operating environment
The units may only be operated in a clean, dry environment.
Please make sure that no objects or liquids can enter the casing through the
ventilating apertures.
Because of the risk of sparks, the unit must not be operated in the vicinity of
flammable gases or fumes.
Cooling
To ensure a adequate cooling, the ambient temperature must not exceed
40°C
.
This unit is air cooled by convection or at units >800J/s by forced ventilation.
Therefore , please ensure an adequate air-flow is available, and ensure that nothing is
placed either above or below the unit which may impede this air-flow.
Don’t operate table top units without the mounted legs.
Do not expose the unit directly to solar radiation.
If the unit is used as a plug-in component, sufficient air-flow must be provided,
(1HU = 44,5 mm above and below clear).
Opening the unit
Before opening, ensure that the unit is disconnected from the mains!
The unit may be opened by operating personnel only for the purpose of operating
switches as described in the operating instructions, (e.g. baud rate switch of Probus V,
which is inside).
Danger:
The electronic boards inside the power supply are connected to one output
pole. During operation, the electronic boards lie on up to 2000V.
ATTENTION!
The unit contains capacitors, which discharge only very slowly (typical
discharge time 5 min) or, in worst case, do not discharge at all.
For switch over
use isolated tools only.
Maintenance or repair of this unit should only be carried out by trained service
personnel who are aware of the inherent dangers of such equipment.
