Multilin 的 750-P5-G1-S1-HI-A20-GE 实现了两种不同的安全功能，以减少对设定点配置的未授权访问；键盘编辑设定点所需的硬件跳线和键盘和 EnerVista 750 设定点编辑所需的八字符字母数字密码。

继电器的出厂默认密码“0”对限制设定点管理没有实际作用，所以用户要想安全功能正常运行就必须调整密码。

GE Multilin 的 1601-0120-AE 手册为继电器的成功运行提供了一些警告。首先，继电器的后部在通电时非常危险，因为高压会导致死亡或重伤。此外，出于类似原因，带电 CT 的二次回路不应断开。

最后，逻辑输入湿触点应连接到低于 300 V DC 的电压，以免发生系统损坏。

Multilin's 750-P5-G1-S1-HI-A20-GE implements two different security features to reduce unauthorized access to setpoint configurations; Hardware jumpers and keyboards required for keyboard editing set points and eight-character alphanumeric passwords required for EnerVista 750 set point editing.

The factory default "0" password of the relay has no practical effect on limiting set point management, so the user must adjust the password for the security feature to function properly.

GE Multilin's 1601-0120-AE manual provides a number of warnings for the successful operation of relays. First, the back of the relay is very dangerous when energized, as high pressure can cause death or serious injury. In addition, for similar reasons, the secondary circuit of a live CT should not be disconnected.

Finally, the logic input wet contact should be connected to a voltage below 300 V DC to avoid system damage.
