Rules for connecting TSX PSY supply modules
(Original Document)
About us
General points
The TSX PSY ••• power supply modules on each rack are equipped with a non-removable terminal block, provided with a cover, which is used to connect the power supply, the alarm relay, the protection ground and, for alternating current supplies, the supply of the 24 VDC sensors.
This screw terminal block is equipped with captive clamp screws which can connect a maximum of 2 wires with a cross-sectional area of 1.5 mm 2 (14 AWG) with wire end ferrules, or one wire with a cross-sectional area of 2.5 mm 2 (12 AWG) (maximum tightening torque on screw terminal: 0.8 N.m (0.6 lb-ft)).
The wires come out vertically towards the bottom. These wires can be kept in place with a cable-clip.

DANGER
ELECTRICK SHOCK - IMPROPER POWER SUPPLY VOLTAGE
For the power supply modules TSX PSY 5500/8500, position the voltage selector according to the voltage power used (110 or 220 VAC).
Failure to follow these instructions will result in death or serious injury.
Provide a protection device and switchgear upstream of the PLC station.
When selecting protection devices, the user should take into account the signaling currents which are defined in the characteristics tables for each supply module.
NOTE: As direct current supply modules TSX PSY 1610/2610/5520 have a strong signaling current, it is not advisable to use them on direct current networks which protect flood-back current limits.
When a power supply module is connected to a direct current network, it is mandatory to limit the length of the supply cable in order to help preventing transmission loss.
  • TSX PSY 1610 supply module:
    • length limited to 30 meters (60 meters there and back) with copper wires and a 2.5 mm2 (12 AWG) cross-section,
    • length limited to 20 meters (40 meters there and back) with copper wires and a 1.5 mm2 (14 AWG) cross-section.
  • TSX PSY 3610 and TSX PSY 5520 supply modules:
    • length limited to 15 meters (30 meters there and back) with copper wires and a 2.5 mm2 (12 AWG) cross-section,
    • length limited to 10 meters (20 meters there and back) with copper wires and a 1.5 mm2 (14 AWG) cross-section.
WARNING
DIRECT CURRENT POWER SUPPLY GROUNDING
The 0 V and physical ground are linked internally in the PLCs, in the network cabling accessories, and in some control consoles.
For applications which use a "floating" installation, measures need to be taken with connections. These depend on the method used for installation. In these cases, it is mandatory to use insulated direct current power supplies.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
