DANGER

DANGER: protection class of the control panel
If the product is installed in a rack, it is likely to

lower the protection class of the rack (protection
against foreign bodies and water) e.g. according to
the EN 60204-1 regulations for switching cabinets.

Take appropriate measures for the control panel to
meet the specifications of the protection class.

3.2 Mains Power Connector

DANGER

DANGER: line voltage
Incorrectly grounded products can be extremely

hazardous in the event of a fault.
Use only a 3-conductor power cable (3×1.5 mm

with protective ground. The power connector may
only be plugged into a socket with a protective
ground. The protection must not be nullified by an
extension cable without protective ground.

The unit is supplied with a 2 m power cord. If the mains cable is
not compatible with your system, use your own, suitable cable
with protective ground.

The socket must be fuse­protected with

4.2 Turning the PGD400 On and Off

Make sure the PGD400 is correctly installed and the specifica­tions in the Technical Data are met.

Turning the PGD400 on

The power switch is on the rear of
the unit.

Turn the PGD400 on with the
power switch (or centrally, via a
switched power distributor, if the
unit is incorporated in a rack).

After power on, the PGD400 …

• automatically performs a self-test

• displays the firmware version F-1.01 for 3 s

• identifies if a gauge is connected

• activates the parameters that were in effect before the last

power off

• switches to the Measurement mode

Turning the PGD400 off

Turn the PGD400 off with the power switch (or centrally, via a
switched power distributor, if the unit is incorporated in a rack).

Wait at least 10 s before turning the PGD400 on again in

order for it to correctly initialize itself.
