4.1 General data and operating conditions
Conformity and approval
Conformity
CE 2006/95/EC Low-Voltage Directive
Approval
UL UL 508C  Device size 1 ... 7 (0.25 ... 45 kW)
 Certification of the integrated safety system: see chapter
10.9
CSA CSA 22.2 No. 14

Device size 1 ... 7 (0.25 ... 45 kW)
 Only if an external mains choke is used.
Protection of persons and device protection
Type of protection
EN 60529 IP 20  183 Specification
 applies to the fully
assembled state ready
for use
 does not apply to the
wire range of the
terminals
NEMA 250 Protection against accidental
contact acc. to type 1
Insulation resistance EN 61800-5-1 Overvoltage category III
Above 2000 m amsl: Overvoltage category II
Control circuit isolation EN 61800-5-1 Safe mains isolation via double / reinforced insulation for
star-point earthed mains with a rated voltage for external
conductors / star point of up to 300 V.
Short-circuit strength
Earth-fault strength
EN 61800-5-1 Motor connection: Limited, i.e. an internal protective device
responds, the controller is inhibited
(Error acknowledgement is required)
Control terminals: Without limitation
Protective measures
against

Short circuit
 Earth fault
(Earth fault strength depends on the operating status)

Overvoltage
 Motor stalling
 Motor overtemperature
(PTC or thermal contact, I 2 t-monitoring)
Leakage current EN 61800-5-1 > 3.5 mA AC, > 10 mA DC Observe regulations and
safety instructions!
Mains switching  Mains switching 3 times in 9 minutes (without
restrictions)
 More frequent mains switching, e.g. during setting-up
operation, does not harm the controller.
– Devices of up to 22 kW are protected against overload.
A monitoring issues the ”Su03” message. The message
must be acknowledged via mains switching. Before you
switch on again: Let the device cool down!
– Devices from 30 kW are protected by the dimensioning
of the load circuit. Monitoring is not carried out.
