Safety instructions

  These safety instructions are intended to ensure safe usage. Failure to follow these instructions in accordance with general safety guidelines concerning electricity may result in risk of electric shock, fire and/or life- threatening injury.

DANGER – DANGEROUS VOLTAGES

WARNING – This installation manual is only intended for qualified personnel. To avoid electric shock, do not perform any work other than that described in this installation manual unless you are qualified to do so.

The use of this device is expressly forbidden in the following situations:

• In locations with a gas or dust explosion hazard and in the vicinity of explosive or highly flammable substances.
• If the device is located in or near water.
• If the product or individual components are damaged.
• By children or persons who are not capable of understanding the risks involved in using this device.

Xemex NV is not liable in any way for damages and the warranty on the device becomes void in the following situations:

• If the ambient temperature is lower than -10°C or higher than 55°C.
• If the device has been subjected to improper use, installation or maintenance.
• If the device is disassembled, modified or repaired.
• If the instructions are not followed.
• If the device is used in the vicinity of explosive or highly inflammable substances or in or near water; or in the case of normal wear and tear.
• If there is a fault in the distribution network.
• As a result of a force majeure situation or if the damage is caused from outside.

PLEASE NOTE! Always adhere to the following checklist:

1. Only qualified personnel or authorised electricians may install the Xemex Smart Charge Controller. Mains voltages above 50VAC may cause personal injury or even death!
2. Follow all applicable local and national electrical and safety regulations.
3. Install the device in an electrical enclosure (panel or junction box) or in an electrical room with limited access.
4. Check that the circuit voltages and currents are within the correct range for the Smart Charge Controller.
5. Use current transformers (CTs) with built-in TVS (= transient voltage suppressor) with a dielectric strength of 3.5KV 50Hz 1min minimum and an operating voltage of 660V. Do not use current output current transformers (ratio) such as 1 amp or 5 amp current transformers: they may irreversibly damage the Smart Charge Controller.
6. Ensure that current transformers are placed behind fuses or circuit breakers.
7. Equipment must be disconnected from DANGEROUS voltages before they are manipulated. Do not carry out any work on the device when it is still live.
8. If a fault or defect is detected, the device must be switched off immediately. To do this, first switch off the mains power and then contact should be made with the supplier.
9. Before switching on the power, check that all wires are securely fastened by pulling on each wire.
10. Do not install the Smart Charge Controller in a location where it may be exposed to temperatures below -10°C or exceeds 55°C, excessive moisture, dust, salt spray or other contaminants. The device requires an environment with a pollution degree (PD) no worse than 2 (normally only non-conductive pollution; occasionally a temporary conductivity caused by condensation should be expected).
11. Do not drill any mounting holes in the device. Instead, snap the module onto a DIN rail.
12. If the Smart Charge Controller is not installed correctly, the safety features may be compromised.

Storage and transport

• The Smart Charge Controller should be stored safely in a dry, ventilated area, not exposed to direct sunlight. The packaging is not weatherproof.
• The Smart Charge Controller should be stored at a temperature between -20°C and 80°C.
• Make sure that the packaged Smart Charge Controller is exposed to minimal vibration during transport. Transport / move the packaging carefully.
• Pay attention to ergonomic conditions such as lifting, bending, reaching, etc. while working on the device.
