tures, it may only be maintained and/or repaired by qualified
service providers.

This supplement and the operating instructions include
all safety precautions necessary for operator protection,
for the protection of the electronic load and the con­nected devices.

Please make sure to read the detailed operating instructions in
pdf format (spl-series-ba_gb.pdf) on the attached CD-ROM or
at www.gossenmetrawatt.com.
This supplement to operating instructions is no substitute for
the detailed instructions!

The following general safety precautions must always be adhered
to during operation, maintenance and repair of the device. Non­compliance with these safety precautions, or with other explicit
warnings included in this supplement and in these operating
instructions, is deemed a violation of design-specific safety stan­dards and use for intended purpose. The manufacturer assumes
no liability in the event of noncompliance with these safety pre­cautions.

Safety Precautions
1 The device may only be operated in accordance with the pro-

cedures included in this supplement and in the operating
instructions.

2 High-voltage conducting components are located inside the

device, which must not be contacted directly.

3 Read the operating instructions carefully before placing the

instrument into service, in order to assure your own safety.

4 The device must be grounded.

The device is equipped with a protective earth terminal. The
device chassis and the housing must be grounded in order to
eliminate the danger of electrical shock. The device may only
be connected to mains power by means of a 3 conductor
cable, and the protective conductor must be securely con­nected with the protective conductor terminal of the mains
outlet.

5 Keep away from voltage conducting electrical circuits!

Operating personnel may not remove any of the device’s cov­ers. Only trained personnel are permitted to replace compo­nents and change internal settings. Components may not be
touched as long as the power cable is connected.
Dangerous voltage may be present even after the power cable
has been disconnected from the mains.
The device must be disconnected from the mains, electrical
circuits must be discharged and external voltage sources
must be disconnected before touching any components, in
order to prevent personal injury.
Due to the fact that additional danger may otherwise occur,
only original replacement parts may be used and the device
may not be modified in an unauthorized fashion. In order to
assure uninterrupted functionability of the device’s safety fea-

Connecting the Power Cable
1 Examine the voltage selector switch on the back of the device

in order to assure that the selected voltage coincides with
available mains power. If this is not the case, observe the note
printed on the device’s mains inlet plug, and make sure that
the correct fuse is utilized.

2 The on/off switch in the device’s front panel must be switched

off before the power supply is connected to the mains.

3 Connect the 3 conductor cable with plug to the mains outlet.

The device must be connected to the protective earth con­ductor.

4 Press the switch on the front panel in order to turn the device

on. The device is now ready for operation.

The fuse is located in proximity to the mains power inlet plug on
the back of the device.
Observe the following points if the setting of the input voltage at
the switch provided for that purpose is changed and/or the fuse is
replaced:

1 The on/off switch must be turned off and the power supply

must be disconnected from all other devices before changing
the setting of the input voltage at the switch provided for that
purpose and/or replacing the fuse.

2 Press the fuse holder with an insulated screwdriver and the

fuse pops out.

3 Pull the fuse out of the fuse holder and replace it with a new

one which complies with the specifications on the label next
to the mains plug.

Use approved fuse types only in order to prevent dam­age to the device.

4 If input voltage needs to be changed, replace the fuse as

described above and then set the voltage selector switch to
the desired position (230 V AC or 115 V AC). The selected
input voltage appears at the selector switch.

Connecting devices to the electronic load
1 For reasons of safety, make sure that there are no short-cir-

cuits between the positive and negative terminals. The device
is equipped with short-circuit protection, but a short-circuit
may result in injury to the user (e.g. risk of fire).

2 The output cable must be insulated all the way up to the con-

nected power consumer.

It is imperative that the hazard warning should be ob­served!

3 The electronic load is equipped with high-current screw terminals of

protection type IP00 for the connection with power sources.

4 The electronic load may be connected with DC power sources up to a

voltage of:
SPL 250-30 as well as SPL 400-40: max. 84 V DC
SPL 200-20 as well as SPL 350-30: max. 210 V DC

If the load is connected to a voltage greater than the standardized
exposed extra-low voltage, the user must take care to provide a suffi­ciently safe cover as a protection against accidental contact.
