安装
操作产品前，需检查产品外壳、控制件等是否有机械损
坏。
必须使用所供
Sub-D
插头来连接。
如发现有任何损坏，不可将产品连到市电。打开产品前断
开电源插头。
应由受训工程人员执行本机的服务、维修或校正。
本机仅能在铭板规定电压下操作。如需更换保险丝，有一
点极其重要，即：仅能用与原厂所配保险丝规格和外形尺
寸相同的保险丝来替换。
更换保险丝时应将本机与市电断开。
接地
本机仅可在接地良好的电源插头下操作。因为它通要过电
源线的地线作为产品引线的地。该安全特征不可因无接地
线的扩展线而中断。
制冷
任何时候都必须保持空气流通顺畅，这点非常重要。
注意！
本产品会产生危险电压。故非受训人员不能操作改产
品，也不可打开产品外壳！
过温保护
(OT)
如果产品过热（如：风扇坏，进风孔和排气孔太脏等），产
品将自动关闭，且
"OT"
灯会亮。产品冷却后又自动打开。
OT LED
会指示模拟接口的
LOCK
信号没有连接。
环境条件
操作过程中，不论是满载操作还是恒定值操作，环境温度
应在
0...50°C
之间。储存温度可为
-40°C
和
+70°C
。相对湿
度不应超过
90%
，且无凝露。
Installation
Before taking the unit into operation it is necessary to inspect
the housing, the controls etc. for signs of physical damage.
The supplied Sub-D plug must be connected.
If any damage is found, the unit may not be operated on the
mains. Disconnect the mains plug before opening the unit.
Servicing, repairs or calibrations should only be carried
out by trained engineers.
The unit must be operated only on the voltage stipulated
on the type plate. If it is necessary to change the fuse, it is
imperative that it is only replaced by one of same value and
physical dimensions as the original supplied fuse.
The unit must be disconnected from the mains whilst
replacing the fuse.
Grounding
The unit may only be operated using a proper ly wired and
grounded mains plug as the grounding of the unit leads
via the earth line of the power cable. This safety feature
must not be disabled by using an extension cable without
a ground lead.
Cooling
It is important that the air circulation remains unimpeded
at all times.
ATTENTION!
The unit generates hazardous voltages. It must not
be operated by untrained personnel and not with
open cover!
Overtemperature protection (OT)
If the unit is overheated (e.g. fan defective, ventilation in-
and outlets dirty etc.), it will automatically switch off and
the LED "OT" will light on. After cooling down the unit will
switch on automatically.
The OT LED also indicates that the LOCK signal on the
analog interface (rear side of device) is not bridged.
Ambient conditions
During operation, at full load or constant operation, the
ambient temperature may lie between 0...50°C. The storage
temperature can be between -40°C and +70°C. The relative
humidity should not exceed 90%, non-condensing.
