Note:
¾Power input (PWR): INV-4E1 interface converters support three kinds of voltage, 220VAC, -48VDC and +24VDC.
Please pay attention to the DC input and it’s negative polarities. It is better to use a multimeter to check if the
power polarity and voltage value are according with those marked on equipment.
¾Ensure to fix a reliable grounding wire at the grounding point on the equipment.

6. Installation
Before installing the equipment, check the following conditions.
6.1 Field requirements
Clean and well ventilated.
Dry environment (relative humidity: 20% - 95%, no condensing).
6.2 Power supply
There shall be power supply applicable to the equipment in the installation field.
6.3 Cable Connection
6.3.1 LAN connection
The equipment provides auto MII/MIIX interface in conformity with IEEE 802.3 protocol standard to support 10/100M
full/semi-duplex work modes. It can run in any Ethernet work mode, i.e. supporting any Ethernet interface. According to
the actual situation, prepare a crossed or straight-line cable in cooperation with RJ45 and connect one end with the UTP
interface on the back board of the equipment and the other end with PC or SWITCH. When the equipment is open, if the
connection is correct, LINK light will be ON.
6.3.2 E1 connection
Insert the accessory BNC coaxial cable connector into E1 PORT. Then connect the equipment with transmission
equipment (such as PDH or SDH optical multiplexer) with the coaxial cable.
zCheck whether the E1 circuit is shortly connected, broken or poor in connection. If it goes through SDH equipment,
the configuration of E1 circuit by network management must be checked.
zThe error code rate of E1 circuit measured by an error code instrument must be lower than 10-7.
