Basic safety instructions

3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any

• contingencies and events which may arise during the installation, operation and maintenance of the devices.

• local safety regulations; the operator is responsible for observing these regulations, also with reference to the

installation personnel.

DANGER!

Risk of injury from high pressure in the equipment/device.

▶Before working on equipment or device, switch off the pressure and deaerate/drain lines.

Risk of electric shock.

▶Before working on equipment or device, switch off the power supply and secure to prevent reactivation.

▶Observe applicable accident prevention and safety regulations for electrical equipment.

General hazardous situations.

To prevent injury, ensure that:

▶In the potentially explosion-risk area the positioner Type 8696 may be used only according to the specification

on the separate approval sticker. For use observe the additional instructions enclosed with the device together

with safety instructions for the explosion-risk area.

▶Devices without a separate approval sticker may not be used in a potentially explosive area.

▶The system cannot be activated unintentionally.

▶Installation and repair work may be carried out by authorised technicians only and with the appropriate tools.

▶After an interruption in the power supply or pneumatic supply, ensure that the process is restarted in a defined

or controlled manner.

▶The device may be operated only when in perfect condition and in consideration of the operating instructions.

▶The general rules of technology apply to application planning and operation of the device.

To prevent damage to property of the device, ensure:

▶Do not feed any aggressive or flammable media into the pilot air port.

▶Do not feed any liquids into the pilot air port.

▶When unscrewing and screwing in the body casing or the transparent cap, do not hold the actuator of the pro-

cess valve but the connection housing of Type 8696.

▶Do not put any loads on the body (e.g. by placing objects on it or standing on it).

▶Do not make any external modifications to the device bodies.

Type 8696

Basic safety instructions

NOTE!

Electrostatic sensitive components / modules.

The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact

with electrostatically charged persons or objects is hazardous to these components. In the worst case scenario,

they will be destroyed immediately or will fail after start-up.

▶Observe the requirements in accordance with EN 100 015 - 1 to minimise or avoid the possibility of damage

caused by sudden electrostatic discharge.

▶Also ensure that you do not touch electronic components when the power supply voltage is present.
