IM300 Intelligent Power Monitoring Instrument

1. Introductions

1.1. Function Specification

IM300 is an intelligent multipurpose power parameter monitoring and control

device which has an extensive range of applications in 6~35kV or 0.4kV power

systems. It has the data acquisition, control and statistical functions, such as electrical

parameters measurement, calculation and statistics, fault records, 2 ~ 31st

harmonics monitoring function, 4-ch digital inputs and 2-ch relay outputs, 1-ch

4~20mA DC transmission output, over-limit alarm and other functions. IM300 is

equipped with RS485 communications and MODBUS-RTU protocol for integration

into any power monitoring and control system. The appearance is shown in fig 1.1.1.

2.1.2. Installation

The IM300 should be mounted on the switch gear panel.

Panel opening dimensions shown in fig. 2-1-2-1:

Fig 2.1.2.1 Slots on the panel (unit: mm) Fig 2.1.2.2 Card is removed

Taking into account the length of wire, the rear panel must be 100mm depth for

accommodating IM300. Actual installation, it normally takes the rear there is

some space (at least 130 × 130 × 100mm), ease of installation and wiring.

Take off the installation card on both sides of the device., as shown in fig. 2.1.2.2,

with the thumb and forefinger of one hand the fixed head gently lift (lift force is

not too large, otherwise it may cause the fixed head fracture), the thumb of the

other hand in the direction of the arrow shown in FIG by pushing the catches can

be removed. When installing the device on the front panel push into the mounting

hole, then from the trench along the rear of the device will be installed on clip. As

shown in fig. 2.1.2.3, his hands were holding down the top and bottom sides of

the device, the top two in the thumb of the clip ends, even before the direction of

the arrow to push hard to make catches squeezing panel. After the installation of

two cards are installed, the device will be firmly fixed on the panel.
