Caution in Handling
●
PSA-24/PSA-24L Power Supplies are the power supply units dedicated for IAI
controllers of the 24V DC type.
●
Do not attempt to connect in parallel several power supply units in different
capacities. Do not attempt to connect PSA-24 (without fan), PSA-24L (with fan)
and PS-24 in parallel. Connect PSA-24 with only PSA-24, or PSA-24L only with
PSA-24L in parallel.

Heatsink and Mounting Method
In the figures below show the minimum distance between the control panel and walls and
minimum distance among power sources in parallel operation.
Also, make sure to keep the temperature below the ambient temperature specified for the
power source when design and install the control panel.
Caution: The main housing of the product gets so hot that it sometimes gives you a
burn as it works as a heat sink.
Do not touch while the power is on, or even after the power is off until the
heat calms down.
