Operating Instructions, 07/2012, A5E03728167
CAUTION
Static discharges on surfaces or interfaces (e.g. terminal or connector pins) can cause
malfunctions or defects. Therefore, when working with inverters or inverter components,
ESD protective measures should be observed.
Transport and storage
CAUTION
Protect the equipment from physical shocks or vibration during transport and storage. It is
important that the equipment is protected from water (rainfall) and excessive temperatures.
Installation
WARNING
Only permanently-wired input power connections are allowed. The equipment must be
earthed (IEC 536 Class 1, NEC and other applicable standards).
Wherever faults occurring in the control equipment can lead to substantial material damage
or even grievous bodily injury (that is, potentially dangerous faults), additional external
precautions must be taken or facilities provided to ensure or enforce safe operation, even
when a fault occurs (e.g. independent limit switches, mechanical interlocks, etc.).
Make sure the motor is configured for the correct supply voltage.
Mount the inverter vertically to a flat and non-combustible surface.
Requirements for United States / Canadian installations (UL/cUL)
Suitable for use on a circuit capable of delivering not more than 40000 rms Symmetrical
Amperes, 480 Vac maximum, when protected by UL/cUL-certified Class J fuses only. For
each frame size A to D use class 1 75 °C copper wire only.
This equipment is capable of providing internal motor overload protection according to
UL508C. In order to comply with UL508C, parameter P0610 must not be changed from its
factory setting of 6.
For applications where UL approval is required, only AC voltage can be applied to the
Relay Output (DO2) terminals (maximum 250 V).
For Canadian (cUL) installations the inverter mains supply must be fitted with any external
recommended suppressor with the following features:
•
Surge-protective devices; device shall be a Listed Surge-protective device (Category
code VZCA and VZCA7)
•
Rated nominal voltage 480/277 VAC, 50/60 Hz, 3-phase
•
Clamping voltage VPR = 2000 V, IN = 3 kA min, MCOV = 550 VAC, SCCR = 40 kA
•
Suitable for Type 1 or Type 2 SPD application
•
Clamping shall be provided between phases and also between phase and ground
