This section is for the installation of a mains shield for the FC series frequency converter frames D1, D2 and E1. It is not possible to install in the IP00/

Chassis versions as these have included as standard a metal cover. These shields satisfy VBG-4 requirements.

Ordering numbers:

Frames D1 and D2: 176F0799

Frame E1: 176F1851

Torque requirements

M6 - 35 in-lbs (4.0 N-M)

M8 - 85 in-lbs (9.8 N-M)

M10 - 170 in-lbs (19.6 N-M)

3.5. F Enclosure Panel Options

Space Heaters and Thermostat

Mounted on the cabinet interior of F enclosure frequency converters, space heaters controlled via automatic thermostat help control humidity inside the

enclosure, extending the lifetime of drive components in damp environments.

Cabinet Light with Power Outlet

A light mounted on the cabinet interior of F enclosure frequency converters increase visibility during servicing and maintenance. The housing the light

includes a power outlet for temporarily powering tools or other devices, available in two voltages:

•

230V, 50Hz, 2.5A, CE/ENEC

•

120V, 60Hz, 5A, UL/cUL

Transformer Tap Setup

If the Cabinet Light & Outlet and/or the Space Heaters & Thermostat are installed Transformer T1 requires it taps to be set to the proper input voltage.

A 380-500 V drive will initially be set to the 525 V tap and a 525-690 V drive will be set to the 690 V tap to insure no overvoltage of secondary equipment

occurs if the tap is not changed prior to power being applied. See the table below to set the proper tap at terminal T1 located in the rectifier cabinet. For

location in the drive, see illustration of rectifier in the

NAMUR Terminals

NAMUR is an international association of automation technology users in the process industries, primarily chemical and pharmaceutical industries in

Germany. Selection of this option provides terminals organized and labeled to the specifications of the NAMUR standard for drive input and output

terminals.

RCM (Residual Current Monitor)

Designed for monitoring residual leakage current to ground on supply mains (TN and TT systems), the RCM requires an external measuring transformer

(supplied and installed by customer). Two relays (N.O. or N.C. ) allow separate setpoints for pre-warning (50% of alarm threshold) and alarm conditions.
