Mount the 1797-PS1E Power Supply

Follow these directions to properly install the 1797-PS1E power supply. Refer 
to the “Commissioning, Installation” section, page 7, for important 
precautions and considerations.

1.

Remove the screws on the cover of the power supply EEx “e” 
terminal box to access the input and output terminals.

2.

Thread the blue IS-safe output power wiring through the blue IS 
compression seals.

3.

Connect the blue IS-safe output power wiring to the output terminals 
making sure all connections are tight.

These power supply outputs provide the input power to the FLEX Ex 
modules.

4.

Thread the hazardous incoming power wiring through the black 
compression seals.

5.

Connect the hazardous incoming power wiring to the input terminals 
making sure all connections are tight.

You can daisy chain the hazardous incoming power wiring to further 
supplies to simplify system wiring.

ATTENTION

Use star washers and nuts to make sure you have a good 
electrical connection. Scrape the paint off the back panel in 
those areas where grounding bolts will be located.

ATTENTION

Keep hazardous and IS-safe wiring separated in a 
suitable fashion. Do not leave long, excess wiring that 
could bridge between the hazardous and safe areas.
