I Connection HV Control
5.3.2 Mains Connection
The mains connection on the rear panel ( Figure 7, C, page 18)has been designed to
accept a mains cord which on the instrument side is equipped with a cold-device plug.
NOTICE: Mains cord
Included in the delivery of the instrument is a mains cord. If the plug on the
mains power side is not compatible with your mains power outlets, you will
need a mains cord which meets the following specifications:
Three-wire cable with protective earthing.
Conductor cross-section: 3 x 0.75 mm² or greater.
Cable length 2.5 m maximum.
DANGER: Mains voltage
Appliances, which have not been professionally connected to Earth, can be
life-threatening in the event of a malfunction. For this reason use three-wire
mains cords, respectively extension cords with protective earthing only. Insert
the mains plug into a mains power socket, which provides an Earth contact.
Insert the plug of the mains cord into the mains socket provided on the instrument.
Insert the mains plug of the mains cord into the mains outlet.

5.3.3 Earthing
With the aid of the earthing screw ( Figure 7, B, page 18) the multichannel gauge can
be connected to the protective ground of the vacuum chamber.
NOTICE: Earthing
Connect the Earth connection on the vacuum chamber by means of a
protective earth conductor to the earthing screw on the instrument
5.3.4 Sensor
The connection marked Sensor serves the purpose of connecting sensors. For each
measurement channel an 8-way modular socket is available. ( Figure 7, E, F, G, page
18 and Figure 8, page 19).

CAUTION: Impermissible Sensors.
Connecting sensors which have not been designed to be operated in
connection with the multichannel gauge or which do not comply with current
EMC guidelines can impair operation of the instrument or even damage it.
Always operate the multichannel gauge with approved sensors.  Chapter
3.2 Suitable Sensors, page 10 .
Connecting:
Measurement channel 1, 2 and/or 3: Connect of the sensor using a shielded straight
through cable to the connection CH1, CH2 and/or CH3.
5.3.5 Relay
The switching functions and the ready monitor influence the switching action of various
relays within the multichannel gauge. Through the connection marked Relay ( Figure
7, D, page 18 and Figure 9, page 19) you may utilise the relay contacts for switching
purposes. The relay contacts are floating.

5 SP 2 Common contact (COM)
6 SP 2 Normaly open contact (NO) or Ready contact
DANGER: Dangerous voltage
Voltages exceeding 60 VDC or 30 VAC are dangerous when touched. You
may only switch at the connector marked Relay Output voltages of 30 VDC or
30 VAC with a maximum current of 1 A. The voltage must comply with the
requirements of a safety extra-low voltage (SELV-E in accordance with EN
61010).
