3.2.1 Connection
hints
Conditions for the Ex e clamps
Min. and max. clamping torque
min. 0,3 Nm
max. 0,4 Nm
Min. und Max. wire cross- section steep: 0,2 – 2,5 mm²
flexible: 0,2 – 2,5 mm²
Consider the following items while connecting und starting
LINE VOLTAGE!
Extreme caution is advised when handling this de-
vice. High electrical discharge is possible and can
be fatal.
Please note the following Standard of Compliance:
BVS 10 ATEX E 112, IECEx BVS 10.0095 and the
regulative DIN EN 60079-14.
Do not exceed terminal safety limits of each termi-
nal.
See limits in technical details or declarations of conformity.
The breaking current of the built-in valve fuse must
correspond to the used solenoid valve
3.2.2 Switching power off ability
The maximum current limits (5 A) on the clamps 28,
29 and 30, 31 should not be exceeded at any time!
E.G. By an application of switched power supply a multiple higher cur-
rent as the nominal max. current may occur. In this case a switching on
current limitation (e.g., NTC) must be added to avoid the off-limits high
current.
If this is missed the risk of welded relay contacts and within the loss of
the explosion protection exists!!
