The PSM24… power supply module supplies

the excom system with power to the full extension. The power supply module can be used

in Zone 2.

Powered with 24 VAC. The external power

supply is hooked up to Ex e clamps at the

module rack. Any contact with the clamps in

energized state should be avoided. They are

located below a closure cap. Switch off power

before contact.

Redundancy:

Two power supply units can be installed in

combination with a suitable module rack. In

case of power cut or failure of one device, the

second unit provides the power for the whole

system. Different potentials can be supplied.

PSM24-3G compatibility mode:

The PSM24-3G can be replaced by the new

PSM24-3G.1 or both can be operated in parallel on a module rack.

Important note:

When changing from the PSM24-3G to the

new PSM24-3G.1, the knurled screw must

be removed from the module rack. The

PSM24-3G.1 is switched on and de-energized

using the provided locking clip PSM24-LC.

IoT mode:

In IoT mode, additional data can be provided. The PSM24-3G.1 power supply module

cannot be operated in compatibility mode in

this scenario. Evaluation is carried out via

the excom Ethernet gateway GEN-… with a

firmware version ? 1.5.2.0. The following data is provided: power supply module available;

maintenance recommended acc. to NE107;

output current too high; actual input voltage;

input voltage undershot or overshot; lowest input voltage; highest input voltage; operating

■ DC power supply module, supplies a module rack in Zone 2

■ Switch on/de-energize using the provided

locking clip PSM24-LC

■ The knurled screw must be removed from

the module rack!
