1 Introduction
1.1 System Overview
The Apex 100 Rack is a multi-functional, electronic, electricity energy meter used for grid metering. It provides
high accuracy in measuring electrical and also in measuring instantaneous quantities such as current, voltage,
power, frequency etc. The Apex 100 offers extensive configurable functional features together with the high
accuracy enable application areas more numerous than for traditional electricity meters. Besides having well
designed traditional features such as meter registers, data logging and tariff capability, there are also extensive
functions for bi-directional communication, monitoring alarm conditions, total harmonics distortion for current
and voltage. The Apex 100 is a 0.2 class CT-PT meter. It supports an open data exchange protocol (as per
ICS DLMS) for ease of reading and integration with other systems.
The meter is available in two major variants:
1. Self-powered
2. APS
The self powered variant meter is powered from its three-phase/three-wire or three-phase/four-wire feeder line.
The auxiliary powered meter takes its power from the auxiliary AC and DC power supply bank.
Figure 1: An Overview
The meter stores data in non-volatile memory. The data transfer possible options available in meter is through
hand held unit (Optical 1107 & USB type A ports) for local reading and GSM/ GPRS modem (RS232 & RS485
serial ports) for remote meter reading applications. Apex 100 is specially designed for supporting data transfer
on TCP/IP channel by supporting in-built Ethernet port in meter.

1.2 About this User Manual
This user manual describes the Apex 100 rack meter‟s functions and provides the information needed to
configure and use the meter. It also explains the different variants and mounting arrangements.
1.3 Important safety information
Care must be exercised during the installation of the Apex 100 meter and associated equipment due to the
presence of mains voltages. Various points under the terminal cover and on the main printed circuit board
(PCB) under the main cover operate at hazardous voltages.
Local best practice and regulatory stipulations must always be observed.
Installation must only be performed by suitably trained personnel.
After installation access to the connectors and conductors must be prevented by fitting the covers supplied,
ensuring that they are secured in position with the screws provided and if appropriate sealed in accordance with
local practice.

regulatory stipulations
must always be observed
when handling batteries

The front cover can be sealed in the closed position. This will stop the front cover from being opened and
restrict unauthorised access to the MD pushbutton and internal areas. There are also sealing points on either
side of the meter for securing it to a rack or frame. The sealing bore diameter is 2.0 mm and is suitable for
Ferrule, NIC & SAFCON type seals.

2.1.3 Replacing the Meter Reading Battery
The meter reading battery is fitted on the self power supply variant of the Apex 100. The meter reading battery
enables a user to take a reading and view the display in the absence of a power supply. Replacing the battery is
an easy task, refer to the figures above and follow these instructions carefully.
1. Remove the front cover seal
2. Rotate the hingedfront cover.
3. Remove the batterycompartment lid.
4. Carefully remove the old battery.
5. Insert a new battery. The battery polaritymarkings are etched on the case.
6. Close the hinged front cover.
7. Seal thefront cover in place.
8. Dispose of the old battery legallyand responsibly.

2.4 Rack Mounting Enclosures
Two rack mounting enclosures are available:
1. Meter Enclosure for a single meter (11”)
2. Meter Enclosure for two meters (19”)
A standardised Essailec plug-in connector is used, of the same type as used by other meters according to
standard DIN 43862. The cable connection is made in the rear of the sub-rack. The meter is connected via the
contact pins after insertion. The connector has a short-circuit protection feature for electrical circuits, permitting
the meter to be withdrawn and inserted into the sub-rack during operation. The Essailec connector is used for
the voltage, current, APS terminals & pulse I/O connections. Communication channels for serial, Ethernet etc
are in the form of RJ45 connector are connected and removed manually.
