The rubber feet can be removed to enable the
unit to be screwed down.
Attention ! Max. reach of screw is 4.5 mm!
4. Electrical connection
• Switch power off before plugs are inserted or
removed!
• Wiring must only be carried out with power off!
• Provide stranded wires with ferrules.
• Check all lines and connections before swit-
ching on the equipment.
• If MA01/1 is used in combination with drive
systems, you must provide additional safety
protection, eg. limit switches.
• Movements or displacements during power
loss are not recognized / captured. Applications
with last value memory need a defined reference
value for correcting movements during power
loss accordingly.
Interference and distortion
All connections are protected against the effects
of interference. The location should be selec-
ted to ensure that no capacitive or inductive
interferences can affect the display or the
connection lines! Suitable wiring layout and
choice of cable can minimise the effects of
interference (eg. interference caused by SMPS,
motors, cyclic controls and contactors).
Necessary measures:
• Only screened cable should be used. Wire
cross section is to be at least 0,14 mm², max. 0,5
mm²
• Wiring to screen and to ground (0V) must be
via a good earth point having a large surface area
for minimum impedance.
• The unit should be positioned well away from
cables with interference; if necessary a protec-
tive screen or metal housing must be provi-
ded. The running of wiring parallel to the mains
supply should be avoided.
• Contactor coils must be linked with spark
suppression.
Power supply
The power can be connected by either the pin plug
strip at the rear, by battery or by using a mains
connection cable. The correct supply voltage is
indicated in the delivery documentation.
