Chapter 3 Mechanical Installation
•Do not install if the HDRU is imcomplete or impaired.
•Make sure that the HDRU is far from the explosive and combustible things.
•Only when the power supply is completely cut-off 10 minutes later can you do the wiring job.
•It is required not only carry the display panel and the cover but also the bottom enclosure of the HDRU.
•Do not play metal into the HDRU when installing.
3.1 Requirement for the Installation Site
Ensure the installation site meeting the following requirements:
•Do not install at the direct sunlight, moisture, water droplet location;
•Do not install at the combustible, explosive, corrosive gas and liquid location;
•Do not install at the oily dust, fiber and metal powder location;
•Be vertical installation on fire-retardant material with a strong support;
•Make sure adequate cooling space for the HDRU so as to keep the ambient temperature among
-10 - +40°C;
•Install at where the vibration is 3.5m/s2in 2 - 9Hz, 10m/s2in 9 - 200Hz (IEC60721-3-3);
•Install at where the humidity is less than 95%RH and non-condensing location;
•Protection level of HDRU is IP20 and pollution level is 2 (Dry, non-conducting dust pollution).
Note:
1. It needs derating use if the HDRU operation temperature exceeds 40°C. The derating value of HDRU shall
be 2% for each degree centigrade. Max. allowed temperature is 50°C.
2. Keep ambient temperature among -10 - +40°C. It can improve the HDRU operation performance if install
at the location with good ventilation or cooling devices.

Chapter 4 Wiring and Application
•Only qualified electrical engineer can perform wiring job.
•The cable on power terminal should have no metal parts exposed in air.
•Do not dismantle HDRU or do wiring operation until the power is cut-off for more than 10 minutes, the internal
charge indicator of HDRU is off and the voltage between (+) and (-) of the main circuit terminals is below 36V.
•The power regenerative unit will produce large leakage current.The GND terminal of unit must be grounded
firmly. Two independent ground wires can guarantee reliable grounding.
•Do not touch the wire terminals of HDRU when it is live. The power terminals are neither allowed connecting to
the enclosure nor short-circuiting.
•The chassis shell should be installed before powering-up. Nobody is allowed to open the shell when HDRU is
living.
•Make sure the HDRU’s power supply voltage is the same as the inverter’s rated voltage.
•HDRU has been passed the withstand voltage test, do not do withstand test on HDRU.
•Do wiring connection according to the wiring figure. Do not connect the HDRU’s DC bus terminals (+) and (-) to
the inverter’s DC terminals (+) and (-).
•Make sure the terminals are fixed tightly.
•Do not play screws, washers and metal bars etc. metal into the HDRU when installing.
•Do not mount the HDRU at the water pipe where may have a water droplet splash.
•Do not supply the damage or parts of insufficiency of the HDRU with power.
•Do not check or detect the signal during the HDRU operation.
4.1 Wiring Requirements
Wiring Requirements
1 For the two power terminals’wiring between the inverter and the HDRU, it is suggested to use the red and
the black of 600V voltage level cable, to prevent the DC bus terminal wiring error.
2 The two lines should be closed and used twisted pair when connect the inverter with the HDRU so as to
reduce the current loop. It suggests that the length of wiring should be less than 2m and not exceed 5m.
3 The interval distance between the control terminal wiring and the power terminal wiring should be greater
than 0.3m so as to reduce the interference to control terminal signal.
4 Caused by filter inductance, HDRU will creates induced voltage in running. The earth terminal of HDRU and
related inverter’s earth terminal should be reliable grounding.

4.4 Fuse Explanation
The DC bus input side of HDRU is built-in fuses whose location is shown as Figure 4-3 or Figure 4-4.
If the HDRU is damaged by accident, these fuses can break off the electrical connection between HDRU
and inverter’s DC bus so as to avoid inverter damage.
When the fuse is damaged, please use another fuse which is the same as the damaged one, such as the
same brand and model. If have any question, please contact us or our suppliers.

4.6 Typical Connection
The typical connection of HDRU and HD series inverter is shown as Figure 4-5.
Figure 4-5 Connection of HDRU
Note:
1. Please connect positive and negative terminal correctly, connect (+) terminal of HDRU DC bus to (+)
terminal of inverter DC bus, connect (-) terminal of HDRU DC bus to inverter DC bus.
2. When power on HDRU and inverter at the same time, and the voltage difference must less than F00.27,
the HDRU works as it should.
Since the filter inductance reasons, the adaptive inverter and the HDRU metal enclosure will induce voltage at HDRU
runtime. Please make sure that ground terminals of the HDRU and the adaptive inverter are reliable grounded,
otherwise there is the risk of electric shock.
