原文估计是电文,没加标点,句读如下
this standby letter of credit will expire on the abovementioned date
这份备用信用证,将于上述提到的日期到期
our liability under this letter of credit will cease
到期后,我方责任就会终止
and will be off no further effect whether this instrument is to be returned to us or not
无论设备是否归还我方,对我方不会产生进一步影响
补充之后,就是对于这个到期日,有个after which 的定语从句的说明,无所谓了,意思还是这个意思
就是说,信用证到期之后,我方对于设备怎么样（合同规定我不管）,你都不能对我有进一步的约束力

你的原文有问题，自己去搞清楚再来。没有办法翻译啊
