1. General description
The MC 11 AC 19" power supply cabinet houses up
to eleven TKH Security (7TE) plug-in modules,
supplying these with the correct DC voltages (see
figure 1a). The leftmost, twelfth slot (Slot 0, see figure
1a,c) holds a module with the mains connector, filter,
fuse and switch.
Two fans on the long side opposite the modules (see
figure 1b) provide system cooling. The mounting
brackets are reversible.
2. Indications and connectors
The connectors and indications shown in figure 1a and
1c are listed in table 1.

circulation of cooling air.
3. The chassis should be connected to safety ground
using the connection on the side wall of the cabinet
(1 in figure 1a).
4. Fasten the line cord to the strain relief stud (see the
hexagon in figure 1c, top)
5. Connect the line cord to the mains and switch on the
cabinet. The electric fans should be working; if not,
switch off and check the power voltage.
6. Switch off the MC 11 AC cabinet and install TKH
Security modules according to the instructions
given in the user manuals of the modules. Unused
slots should be covered with 7TE blanking plates.
7. Switch on the cabinet. Both fans should be working,
blowing outwards.
8. Avoid moisture and accumulation of dust.

4. Technical specifications
The two electric fans must be changed every five
years (replacements may be obtained from TKH
Security). The procedure for mounting new fans is as
follows (see figure 2):

5. Safety and EMC Information
6. Product disposal
The equipment described in this manual has been designed and
tested according to the IEC 60950-1 safety requirements. It is an
IEC safety class 1 product; the ground wire in the line cord must
be connected when operating.
The equipment has been tested and found to meet the EGregulations relating to EMC, and complies with the limits for a
Class B device, pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection against interference
to radio communications in any installation. The equipment does
use radio frequency energy; improper use or special circumstances
may cause interference to other equipment or a performance
decrease due to interference radiated by other equipment. In such
a case, the user will have to take appropriate measures to reduce
such interactions between this and other equipment.
The equipment described in this manual is designed for use by
properly trained personnel. This means that adjustment,
maintenance and repair of the equipment should only be carried

If there is any doubt regarding the safety of the equipment, do
not put it into operation.
This might be the case when the equipment shows physical
damage or is stressed beyond its tolerable limits (e.g. during
storage and transportation).
Before opening the equipment, disconnect it from all power
sources. After disconnection from its power sources, the
capacitors in the equipment may remain charged for some
seconds.
When removing covers or other parts of the equipment, live parts
or terminals may be exposed. If the opened, live equipment needs
calibration, maintenance or repair, only trained personnel, who
are aware of the risks, may perform this.
Any interruption of the ground wire inside or outside the
equipment, or disconnection of the protective earth terminal,
could make the equipment dangerous.
Before any connections are made, the equipment must be
connected to safety ground.
Electrostatic discharge (ESD) can damage or destroy electronic
components. Proper precautions should be taken against ESD
when opening the equipment.
