Pay attention to the appropriate spanner size when selecting
fittings for stainless steel heat exchangers.
TS/TS-I gas connections: SW 17
TS/TS-I condensate out connections: SW 22
4.2.7 Condensate drain connection
Depending on the material, build a connecting line with fit-
tings and tubing or hose between the heat exchanger and
condensate drain. For stainless steel, the condensate drain
can be hung directly from the connecting tube; for hoses, the
condensate drain must be secured separately using a clamp.
The condensate drain can be mounted directly to the heat ex-
changer.
When choosing the option for high-purity oxygen, make sure
to select the suffix -O2.
If the condensate drain 11 LD V 38 is used for high hydrogen
concentrations, the system in which it is installed must be
tested for leaks.
Condensate lines must always be installed with a slope and a
minimum inside diameter of DN 8/10 (5/16").
4.3 Electrical connections
The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
The mains supply of the device must be fused according to the
specifications under technical data.
Potential equalization/static charge
Static charges can result in incendive sparking. Avoid static
charges. Any conductive parts of the cooler must be groun-
ded!

The housing has a connection for an earth/equipotential
bonding conductor. Ensure the housing is adequately earthed
(minimum conductor cross-section 4 mm
Particularly observe the requirements of EN 60079-14!
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
WARNING
High voltage
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the
device as a whole!
Electric strength test
This device is equipped with extensive EMC protection. The
necessary tests were carried out at the factory (test voltage
2.1 kV or 2.55 kV DC depending on approval).
If you wish to check the electric strength again yourself, you
can do so on the entire unit. Only test the device with the spe-
cified values using direct current voltage. Testing the electric
strength with alternating current voltage will damage elec-
tronic components. The recommended voltage in this case is
2.1 kV DC, 2 s. Disconnect all supply lines from the device be-
fore testing. Power can be supplied via the mains connection.
Plug connection
This device has one EN 175301-803 plug each for the power
supply and the signal output. If the lead is connected cor-
rectly, these cannot be confused. Therefore please be sure to
correctly reassemble the plugs after connecting the wires. Be-
low you will find the pin assignments, with the numbers cor-
responding to those on the plugs:
The supply line cross-sections must be suitable for the rated
current. Use a maximum line cross-section of 1.5 mm²
(AWG 16) and a cable diameter of 8 - 10 mm (0.31 - 0.39 inch).
