2.9 Modifying the Relay
FAILURE (Option)
On delivery the relay FAILURE is a resting contact (nor-
mally closed). It can be changed to an operating contact
(normally open).
Warning
Before you open the TURBOTRONIK
please first ensure that the TURBOVAC has
been braked to a complete standstill, and
that the mains power cord is disconnected.
Since, nonetheless dangerous voltages
may occur the unit must only be opened by
a qualified electrician.
For modifying the relays, remove the fastening screw of
the upper cover sheet at the rear and pull out the upper
cover sheet.
Modify the jumper (14/2).
State of delivery resting contact 1-2
Modification operating contact 2-3
Close the TURBOTRONIK again.
We recommend noting all the modifications made on the
unit itself or at least in the Operating Instructions for that
particular instrument.
2.10 Installing the
TURBOTRONIK
Install the TURBOTRONIK.
The heat dissipation of the TURBOTRONIK must not be
obstructed. Insure a sufficient ventilation - the ambient
temperature during operation must not exceed 45°C
(113°F).
If - after installation - the rear of the TURBOTRONIK
is no more accessible, switch on the POWER switch
before mounting and if nec. set the starting delay; refer to
section 3.1.
Warning
If the TURBOTRONIK is built into a rack the
mains plug is not within easy reach. There-
fore install a separation between the TUR-
BOTRONIK and the mains when you build it
into a rack.
Warning
Do not operate the TURBOTRONIK with the
standard mains lead in chemically aggressi-
ve surroundings. If you operate the TUR-
BOTRONIK in chemically aggressive surro-
undings replace the mains lead by a resi-
stant one.
