Discharging the P-603
The P-603 must be discharged in the following cases:

Before installation

When the P-603 is not in use but the electronics remains switched on to ensure
temperature stability

Before demounting (e.g., before cleaning and transporting the P-603 and for
modifications)

If the connecting cable of the P-603 is accidentally disconnected from the electronics
during operation
Requirements

You have read and understood the safety precautions (p. 6).
Tools and accessories
If the P-603 is not connected to the electronics:

Only for P-603 without connector:
10 kΩ discharge resistor (not included in scope of delivery), the touchable parts must be
adequately insulated for the actuator's operating voltage range (p. 17)

Only for P-603 with connector:
Electronics from PI
Discharging a P-603 connected to the electronics

Set the piezo voltage to 0 V on the electronics.
Discharging a P-603 not connected to the electronics
If the P-603 does not have a connector:
1. Ensure adequate protection against touching live parts.
2. Short-circuit the stranded wires of the P-603 for at least a few seconds using a
10 kΩ
discharge resistor .
If the P-603 has a connector:

Connect the voltage connector of the P-603 to the switched off PI electronics, which
have an internal discharge resistor, for at least a few seconds.
Maintenance
The P-603 is maintenance-free.
