Supply Cable; Supply Connections - Siemens ADB MEMOPACK 15 XT Instruction Manual

Dim 6 : DMX 512
• MEMOPACK is a portable dimmer pack designed to be
hand-carried or mounted in a fixed installation.
• MEMOPACK belongs to class I equipment and requires a
safety earth connection in compliance with local regulations.
It is a professional digital dimmer, built in accordance with
European safety standards EN 60950 and EN 60204.
• MEMOPACK has been designed to supply luminaires.
• Lethal voltages are present inside. Access to internal parts
is not required for normal operation.
• Refer servicing to qualified personnel. Always disconnect
from the mains supply before removing the cover.
• Always use original spare parts (fuses, etc.)

Supply Connections

Type of mains supply network
Before you connect electrical equipment, you must verify that it
is adapted to the mains system at your venue. If in doubt consult
the electrician or the utility company.
Protection on the supply side
The power outlet and the supply cable which feed the
MEMOPACK must be adequately protected against overload
and short-circuit by the installation; verify the applicable wiring
regulations.
Supply terminals
Remove the bottom cover to gain access to the terminals. All
connections should be performed by a qualified electrician. The
supply terminals are suitable for cables up to 4 mm
terminals are required. The colour code is blue for Neutral and
Yellow/Green for PE (protective earth).
How to remove the top or bottom cover
• always disconnect the power supply before you remove the
cover
• please refer to the sketch for the position of the screws
which secure each cover. Do not remove any other
screws !

MEMOPACK 15 XT

Supply cable

The size of the Neutral wire must at least be equal to the size of
the phases; reduced-size Neutral wires are DANGEROUS and
are NOT allowed. All supply cables and extension cables should
have all conductors under the same sleeve, in order to reduce
unwanted interferences to audio and video equipment.
The supply cable should be sized for the rating of the
MEMOPACK 15 XT:
• 27 A per phase for three-phase star operation (3 x 400 V + N);
e.g. cable 5 x 4 mm 2 , EPR insulation, 85 Celsius
• 82 A for single-phase operation (230 V + N);
2
e.g. cable 3 x 10 mm , EPR insulation, 85 Celsius
Cables for lower current ratings are only allowed if the protec-
tion devices in the supply installation (supply fuses or supply
circuit-breaker) are selected accordingly.
Spade terminals suitable for cables up to 10 mm
in the single-phase conversion kit.
Operation on a Star system (3 x 400 V + N + Earth)
The standard MEMOPACK is suitable for a three-phase 3NPE
230/400V TN-S system (3 phases + neutral N + Earth; N directly
connected to Earth). The voltage between a phase and the
Neutral must lie between 198 V
and 264 V.
The dimmer protections are
single-pole, in the Live wire, as
required for a three-phase
TN-S supply. Optional 1P+N
and 2P versions are available.
Single-phase conversion kit
The MEMOPACK can under some circumstances be used on
a single-phase supply. L1, L2 and L3 are linked for single-phase
operation; the Live of the supply
system is connected to central
terminal No. 2.
Terminals Nos. 4, 5 and 6 are
always linked; the Neutral of
the supply system is connected
to central terminal No. 5.
WARNING
The MEMOPACK (TN version) will operate on a single-phase
supply, but the user must verify whether single-pole protections
are allowed by the applicable wiring regulations.
The MEMOPACK will operate reliably up to its full rated load (82
A) at 35°C. The actually available power may be limited by the
power supply (cable size, supply fuse rating, supply mcb rating).
