Information on handling the product

	This information includes, for example: recommendations for action, assistance or further information on the product.

Intended use

This device is designed for installation in a housing and is intended for general professional use, for example in industrial control systems or office, communication and measuring equipment.

Do not use this power supply in installations where a malfunction could cause serious injury or danger to human life.

Without additional measures to reduce conducted emissions at the output (e.g. by using a filter), the device is not suitable for supplying a local DC network in residential, commercial and light-industrial environments. No restrictions apply for local DC power networks in industrial environments.

Exclusion of liability

All the components are supplied in particular hardware and software configurations appropriate for the application. Modifications to hardware or software configurations other than those described in the documentation are not permitted, and nullify the liability of Beckhoff Automation GmbH & Co. KG.

Personnel qualification

This description is only intended for trained specialists in control, automation and drive engineering who are familiar with the applicable national standards.

Safety instructions and installation requirements for PS2001-4810-1001 power supply

DANGER

Danger of electric shock, fire, injuries, injuries resulting in death!

Do not use the power supply without proper grounding (protective conductor). Use the terminal at the input terminal strip for the ground connection, not one of the screws on the housing.
Turn power off before working on the device. Provide protection against unintentional reconnection.
Ensure proper wiring by following all local and national regulations.
Do not modify or repair the device.
Do not open the device, as high voltages are present inside.
Avoid foreign objects entering the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Do not touch the device when it is switched on or immediately after it has been switched off. Hot surfaces may cause burns.

	Further notes on installation requirements If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for inspection. Install the device in a housing that provides protection against electrical, mechanical and fire hazards. Install the device on a DIN rail according to EN 60715, with the input terminals on the bottom of the device. The maximum ambient air temperature is +70°C (+158°F). The operating temperature is the same as the ambient or surrounding air temperature and is defined 2 cm below the device. The device is designed for convection cooling and does not require an external fan. Do not obstruct the air flow or cover the ventilation grid! Observe the following installation clearances (see table Minimum installation clearances):

Minimum installation clearances

Output power in relation to the nominal output	Minimum installation clearances (mm)
Output power in relation to the nominal output	top	bottom	Left and right side
< 50%	40	20	0
≥ 50%	40	20	5
≥ 90%	40	20	15

	Further notes on installation requirements (connection and wiring) Ensure that the wiring is correct by following all local and national regulations. The device is designed, tested and approved for branch-circuit currents up to 32 A (IEC) and 30 A (UL) without additional protection. If an external fuse is used, do not use circuit breakers smaller than 10 A (B or C characteristic) to avoid unwanted tripping of the circuit breaker. The input can also be supplied by batteries or similar DC sources. The continuous voltage between the supply voltage and the PE/ground potential must not exceed 375 Vdc. The device is designed to meet the requirements of protection class I according to IEC 61140. An isolating device must be provided for the device input.

	Further notes on operation This device contains no parts that require maintenance. If an internal fuse trips, this is due to an internal defect. The device is designed for areas with a degree of pollution 2 in controlled environments. No condensation or frost is allowed. The device housing offers IP20 protection. The housing offers no protection against spilled liquids. The device is designed to operate in areas between 5% and 95% relative humidity. The device insulation is designed to withstand pulse voltages of overvoltage category III according to IEC 60664-1. The device is suitable for supply from TN, TT or IT networks. The continuous voltage between the input terminal and the PE potential must not exceed 300 Vac. The device is designed for altitudes up to 5000 m (16400 ft).
