Installation - Siemens SIDOOR ATD4 W Series System Manual

Power supply
7.1 SIDOOR NT40
On the output side, the switch mode power supply supplies a 36 V DC (± 3 %) SELV at a rated
output power < 100 W. The device can briefly (< 2 s) deliver a 15 A current to enable fast
acceleration (corresponds to a brief power output of 540 W).
Short-circuit protection
Output X2 is short-circuit proof.
LED display
LED L1 indicates the presence of the output voltage.
Note
If the LED does not light up despite being correctly connected to the X1 supply line and if there
is no measurable output voltage, this indicates a short circuit on the output side or a defective
module!
The device can be operated by the control unit without load to establish whether the module is
defective. If the LED at the output does not light up in this mode of operation, and there is no
measurable voltage at the output, this indicates that the device is defective!

Installation

Requirements
Observe the following installation rules:
• Minimum clearance to surrounding parts: 1 cm
• Even mounting surface
• The installation point should, as far as possible, be vibration-free. The permissible climatic
conditions (operation or storage and transport temperature) must be adhered to
(see Technical data (Page 240)).
• Maximum distance to power supply depending on cable length:
– Connecting cable input line (mains ⇔ NT40): 200 cm
– Connecting cable output line (NT40 ⇔ control unit): 150 cm
• Operation outside the specified temperature range can lead to danger, malfunctions and
failure of the equipment.
• Protection class I
• The device must be installed in places that are accessible only to qualified personnel.
