4.1 Safety notes for installation

WARNING

Mechanical impact effect

Protect the 6DR5**0-*G***-**** version of the positioner from mechanical impact effects that

are greater than 1 Joule; this ensure adherence to the IP66 degree of protection.

When installing, observe the following sequence imperatively to avoid injuries or

mechanical damage to the positioner/mounting kit:

1. Mount the positioner mechanically.

2. Connect the electrical auxiliary power supply.

3. Connect the pneumatic auxiliary power supply.

4. Commission the positioner.

WARNING

Assembling the components

When assembling components, ensure that only those positioners and optional modules

are combined with each other that are approved for the corresponding operating range.

This condition is particularly applicable for the safe operation of the positioner in the areas

of zones 1, 2 and 22, where the atmosphere may be potentially explosive. Observe the

device categories 2 and 3 of the device itself and its optional modules imperatively.

CAUTION

Humid environment/dry compressed air

Install the positioner in a humid environment such that the positioner shaft does not freeze

at low ambient temperatures.

Ensure that water does not seep through an open enclosure or an open gland. Water may

seep through if the positioner is not installed and connected on-site immediately and finally.

As a general rule, the positioner must be operated only with dry compressed air. Therefore,

use the customary water separator. An additional dryer is required in extreme cases. The

use of dryers is especially important when you operate the positioner at low ambient

temperatures. Set the Purge air switch to the "OUT" position when installing on the

pneumatic block, above the pneumatic connections.
