Output For Motor Space Heater (Option +G313); Supply Connection By Busbars (Option +G317); Ready/Run/Fault Lights (Options +G327; Halogen-Free Wiring And Materials (Option +G330) - ABB ACS880-37 Hardware Manual

48 Operation principle and hardware description

Output for motor space heater (option +G313)


The option contains:
•
load switch for providing electrical isolation during service
•
miniature circuit breaker for overcurrent protection
•
terminal block for external supply and heating element(s) connection
The heater is off when the drive is running. The customer controls the heating elements in
the motor windings on and off with the external supply. The power and voltage of the motor
heater depend on the motor.

Supply connection by busbars (option +G317)


The option provides input (supply) terminals and a busbar entry that enable direct
connection to busbar trunking systems.
Ready/Run/Fault lights (options +G327...G329)

These options provide "ready" (+G327, white), "run" (+G328, green) and "fault" (+G329,
red) lights installed on the cabinet door.

Halogen-free wiring and materials (option +G330)


The option provides halogen-free cable ducts, control wires and wire sleeves, thus
reducing toxic fire gases.

V-meter with selector switch (option +G334)


The option contains a voltmeter and a selector switch on the cabinet door. The switch
selects the two input phases across which the voltage is measured.

A-meter in one phase (option +G335)


The option contains an ammeter that reads the current flowing through one (L1) input
phase.

Additional wire markings (options +G340 and +G342)



Standard wire markings

As standard, wires and terminals are marked as follows:
•
Plug-in connectors of wire sets: Connector labeled with designation (eg. "X1"). Both
the connector and the individual wires are marked with pin numbers.
•
Wires without a connector: Connector designation and pin number printed on wire (eg.
"X1:7").
•
Fiber optic pairs: Component and connector designation printed on marker tape.
•
Main input, output and PE terminals: Connector identifier (eg. "U1", "PE") printed on
sticker on terminal, or on insulating material close to the terminal. PE cables marked
with yellow/green tape.
