Safety

Intended use

The two-hand control relay P2HZ X4P meets the requirements of EN 574 Type III C. It
forces a press operator to keep his hands out of the hazardous area during the dangerous
closing movement, so avoiding hand injuries.

The P2HZ X4P is suitable for use on controllers for metalworking presses as a block for
simultaneity.

The device can be used as a hand protection device in accordance with the following tech-
nical regulations:

}

Mechanical presses (EN 692)

}

Hydraulic presses (EN 693)

Or safety circuits in accordance with EN 60204-1; VDE 0113-1.

The supply voltage for the two-hand control relay must only be connected downstream of
the shutdown device in accordance with § 9 VBG 7n5.1/2.

The following is deemed improper use in particular

}

Any component, technical or electrical modification to the product,

}

Use of the product outside the areas described in this manual,

}

Use of the product outside the technical details (see 

Technical details [
